ODT is a non-symbolic debugger and implements similar functionality to Advanced Debugger (adb) on Unix systems.

A debugger is a computer program that is used to debug (and sometimes test or optimize) other programs. GNU Debugger (GDB) is an example of a debugger used in open-source software development. This debugger offers remote debugging, what makes it especially applicable to open-source software development. A memory leak tool or memory debugger is a programming tool for finding memory leaks and buffer overflows.

3, the Xcode suite used the GNU Debugger (GDB) as the back-end for the IDE's debugger. Starting with Xcode 4.3, the LLDB debugger was also provided; starting with Xcode 4.5 LLDB replaced GDB as the default back-end for the IDE's debugger. Starting with Xcode 5.0, GDB was no longer supplied.

When debugging with the Renesas E8 debugger or E8a debugger, UART 1 cannot be used. The debug interface uses only four wires: Vcc, GND, Reset and Mode.

Turbo Debugger (TD) is a machine-level debugger for DOS executables, intended mainly for debugging Borland Turbo Pascal, and later Turbo C programs, sold by Borland. It is a full-screen debugger displaying both Turbo Pascal or Turbo C source and corresponding assembly-language instructions, with powerful capabilities for setting breakpoints, watching the execution of instructions, monitoring machine registers, etc. Turbo Debugger can be used for programs not generated by Borland compilers, but without showing source statements; it is by no means the only debugger available for non-Borland executables, and not a significant general-purpose debugger. Although Borland's Turbo Pascal has useful single-stepping and conditional breakpoint facilities, the need for a more powerful debugger became apparent when Turbo Pascal started to be used for serious development.

The Jasik Debugger (or more correctly, The Debugger from Jasik Designs), was a debugger tool for the classic Mac OS. Pitched as a much more powerful alternative to Macsbug, it was the debugger of choice among professional Mac developers until the advent of more advanced source-level debuggers such as that built into Metrowerks Codewarrior. While Jasik's debugger featured a graphical user interface, it was laid out in a very arbitrary and peculiar way, with buttons seemingly randomly sized and positioned. This gave it a reputation as difficult to use.

Common DeBugGer Protocol as used by Xdebug and potentially other implementations. DBGp is a simple protocol for use with language tools and engines for the purpose of debugging applications. The protocol provides a means of communication between a debugger engine (scripting engine, Virtual Machine, etc.) and a debugger IDE.

A machine language debugger. It was initially included with MAC/65, but the cartridge-based version of the assembler added its own debugger, DDT. BUG/65 was later added to DOS XL.

The GNU Debugger and GNU Emacs were also notable successes.

The initial version was written by Stephen R. Bourne. ADB is the standard debugger on Solaris and the Solaris kernel debugger kadb that was introduced with SunOS-3.5 (1986) is a minor variant of adb. A version of ADB was integrated into the BSD kernel as a kernel debugger. On Solaris, ADB was replaced by the Modular Debugger mdb with Solaris 8 (2000) and the ADB command-line interface now is emulated by mdb when it is called as adb.

Initially, a separate company, TurboPower Software, produced a debugger, T-Debug, and also their Turbo Analyst and Overlay Manager for Turbo Pascal for versions 1 to 3. TurboPower released T-Debug Plus 4.0 for Turbo Pascal 4.0 in 1988, but by then Borland's Turbo Debugger had been announced. The original Turbo Debugger was sold as a stand-alone product introduced in 1989, along with Turbo Assembler and the second version of Turbo C. To use Turbo Debugger with source display, programs, or relevant parts of programs, must be compiled with Turbo Pascal or Turbo C with a conditional directive set to add debugging information to the compiled executable, with related source statements and corresponding machine code. The debugger can then be started (Turbo Debugger does not debug within the development IDE).

The GNU Debugger (GDB) is a portable debugger that runs on many Unix-like systems and works for many programming languages, including Ada, C, C++, Objective-C, Free Pascal, Fortran, Go, and partially others.

Slot 1 was reserved for the Tracer, a hardware debugger system.

For many years both of these products were sold even though active development stopped on them. With Borland's reorganization of their development tools as CodeGear, all references to Borland C++ and Turbo Assembler vanished from their web site. The debuggers in later products such as C++ Builder and Delphi are based on the Windows debugger introduced with the first Borland C++ and Pascal versions for Windows. The final version of Turbo Debugger came with several versions of the debugger program: TD.EXE was the basic debugger; TD286.

Radare2 has a built-in debugger, that is lower-level than the classic GDB. However, it can also interface itself with the GNU debugger, or even WineDBGGmane archive about WinDBG support in radare2 to debug Windows binaries on other systems. It is even possible to use it as a kernel-debugger with VMWare. Also there is a support for the WinDBG protocol.

The debugger, really a monitor, is entered with the `BUG` command. The `X` command returns to EDIT mode. The debugger allows the viewing and changing of registers and memory locations, code tracing, single-step and disassembly.

The debugger does not contain its own graphical user interface, and defaults to a command-line interface, although it does contain a text user interface. Several front-ends have been built for it, such as UltraGDB, Xxgdb, Data Display Debugger (DDD), Nemiver, KDbg, the Xcode debugger, GDBtk/Insight, and HP Wildebeest Debugger GUI (WDB GUI). IDEs such as Codelite, Code::Blocks, Dev-C++, Geany, GNAT Programming Studio (GPS), KDevelop, Qt Creator, Lazarus, MonoDevelop, Eclipse, NetBeans, and Visual Studio can interface with GDB. GNU Emacs has a "GUD mode" and tools for VIM exist (e.g. clewn).

Executing a program under control of a debugger can change the execution timing of the program as compared to normal execution. Time-sensitive bugs such as race conditions may not occur when the program is slowed down by single-stepping source lines in the debugger. This is particularly true when the behavior involves interaction with an entity not under the control of a debugger, such as when debugging network packet processing between two machines and only one is under debugger control. Heisenbugs can be viewed as instances of the observer effect in information technology.

It is widely used for OS development, as it removes the need for constant system restarts (to test code). BFE, described as a "Graphical Debugger Interface for the Bochs PC Emulator", is a graphical interface for the debugger within the Bochs PC emulator that makes it possible to debug software step-by-step at the instruction and register level, much like Borland's Turbo Debugger.

DDT replaced the BUG/65 debugger which shipped with the disk version of MAC/65.

In 1995, Late Night Software released what is now their main product, Script Debugger. At the time, there were several competing AppleScript and Open Scripting Architecture (OSA) language source code editors, including ScriptWizard and Main Event Software's Scripter. As of May, 2005, Script Debugger and Smile remain the only competitors to Apple Computer's freeware Script Editor application. In 2004, the company released Affrus, a Mac OS X native debugger for the Perl scripting language.

A simple (non-symbolic) machine language debugger resides in SYS5/SYS, and an extended command set for this resides in SYS9/SYS (these two files may be deleted for those users not needing the debugger).

Nemiver also provides an event-based debugger library (which currently features a GDB back-end, but others could be added in the future) that could be re-used by other projects seeking to implement a debugger as a part of an integrated development environment (IDE), for example.

Visual Studio includes a debugger that works both as a source- level debugger and as a machine-level debugger. It works with both managed code as well as native code and can be used for debugging applications written in any language supported by Visual Studio. In addition, it can also attach to running processes, monitor, and debug those processes. If source code for the running process is available, it displays the code as it is being run.

In May 2005, a new "alpha" version of the language was made available for testing. This improved second version of the language was bundled with version 4 of Script Debugger. JavaScript OSA was eventually discontinued due to lack of interest and was dropped from Script Debugger 5 in 2012.

The modular debugger (mdb) is an extensible, low-level debugger developed by Sun Microsystems for the Solaris 7 operating system.

At breakpoints, data and program memory can be read and modified using the MPLAB IDE.

SuperTalk came with a source- level debugger well ahead of HyperCard, but the SuperTalk debugger is a modal window and does not let you set breakpoints by just clicking beside a line. A special `trace` command is used to enter the debugger, where one can then view the currently executing line of code, execute commands, evaluate expressions etc. Because of that, the SuperTalk debugger has to be explicitly turned on instead of being available right away when a script error occurs. The `visual effect` command is a little stricter in its syntax, but in exchange supports numerous additional transition effects, including QuickTime transitions and special plug-in modules (stored in data fork resources of type `TRAN`).

EE Times. November 6, 2003. a feature that later also became available in the free GDB 7.0 debugger (2009).

On-line Debugging Tool (ODT) was used to describe several debugger programs developed for Digital Equipment Corporation (DEC) hardware. Various operating systems including OS/8, RT-11, RSX-11, and RSTS/E implemented ODT as did the firmware console of all of the LSI-11-family processors including the 11/03, 11/23/24, 11/53, 11/73, and 11/83/84. The debugger allowed access to memory using octal addresses and data. Within the software systems, the debugger accessed the process's address space.

The BIOS improved the coexistence of DR-DOS with Windows 9x and its support for third-party disk compression drivers such as Microsoft's DriveSpace. It introduced a diagnostics mode (activated by Scroll Lock), integrated debugger support (with DEBUG=ON and a debugger loaded before or from within CONFIG.SYS) and more flexible CONFIG.

If source code is not available, it can show the disassembly. The Visual Studio debugger can also create memory dumps as well as load them later for debugging. Multi-threaded programs are also supported. The debugger can be configured to be launched when an application running outside the Visual Studio environment crashes.

1 (2013). For Linux and OS X, Intel supports extensions to the GNU Debugger (the GDB provided with Intel Composer XE 2013 SP1 is based on GDB 7.5). Intel maintains a fork of GDB and works on its relevant bugs to get them implemented upstream. For Windows, Intel supports extensions to the Visual Studio Debugger.

The retry logic will trigger all the time because the debugger is slow enough to make the read race occur always.

VkTrace is an interactive tracefile debugger for the Vulkan API by LunarG. It was renamed on August 27, 2015 from GLAVE.

SYS driver also adds breakpoints supported in hardware by the 386 and later processors to all three debugger programs. TD386 allows some extra breakpoints that the other debuggers of the era do not (I/O access breaks, ranges greater than 16 bytes, and so on). There is also a debugger for Windows 3 (TDW.EXE). Remote debugging was supported.

A memory debugger is a debugger for finding software memory problems such as memory leaks and buffer overflows. These are due to bugs related to the allocation and deallocation of dynamic memory. Programs written in languages that have garbage collection, such as managed code, might also need memory debuggers, e.g. for memory leaks due to "living" references in collections.

Dr. Watson is an application debugger included with the Microsoft Windows operating system. It may be named `drwatson.exe`, `drwtsn32.exe` or `dwwin.

This annex is new; it provides guidance to debugger developers for features that are desired for supporting the debugging of floating-point code.

IDEs are also used for debugging, using an integrated debugger, with support for setting breakpoints in the editor, visual rendering of steps, etc.

JSwat is a graphical Java debugger front-end, written to use the Java Platform Debugger Architecture. JSwat is licensed under the Common Development and Distribution License and is freely available in both binary and source code form. In addition to the graphical interface, there is a console based version which operates very much like jdb, the debugger included with the Java Development Kit. Features include breakpoints with conditionals and monitors; colorized source code display; graphical display panels showing threads, stack frames, visible variables, and loaded classes; command interface for more advanced features; Java-like expression evaluation, including method invocation.

Some debuggers offer two modes of operation, full or partial simulation, to limit this impact. A "trap" occurs when the program cannot normally continue because of a programming bug or invalid data. For example, the program might have tried to use an instruction not available on the current version of the CPU or attempted to access unavailable or protected memory. When the program "traps" or reaches a preset condition, the debugger typically shows the location in the original code if it is a source-level debugger or symbolic debugger, commonly now seen in integrated development environments.

If a stop error is encountered while a live kernel debugger is attached to the system, Windows will halt execution and cause the debugger to break in, rather than displaying the BSoD. The debugger can then be used to examine the contents of memory and determine the source of the problem. A BSoD can also be caused by a critical boot loader error, where the operating system is unable to access the boot partition due to incorrect storage drivers, a damaged file system or similar problems. The error code in this situation is STOP 0x0000007B (INACCESSIBLE_BOOT_DEVICE).

Windows XP supports cross user session debugging, attaching the debugger to a non-crashing user- mode program, dumping the process memory space using the dump command, and then detaching the debugger without terminating it. Debugging can be done over a FireWire port and on a local system. The debug heap can be disabled and the standard heap be used when debugging.

Other letters are reserved so that customers may write their own commands. TPF implements debugging in a distributed client-server mode; which is necessary because of the system's headless, multi-processing nature: pausing the entire system in order to trap a single task would be highly counter-productive. Debugger packages have been developed by 3rd party vendors who took very different approaches to the "break/continue" operations required at the TPF host, implementing unique communications protocols used in traffic between the human developer running the debugger client & server-side debug controller, as well as the form and function of debugger program operations at the client side. Two examples of 3rd party debugger packages are Step by Step Trace from Bedford Associates and CMSTPF, TPF/GI, & zTPFGI from TPF Software, Inc.. Neither package is wholly compatible with the other, nor with IBM's own offering.

EXE runs in protected mode, and TD386.EXE is a virtual debugger which uses the TDH386.SYS device driver to communicate with TD.EXE. The TDH386.

Addresses in the ODT debugger are 16 bit addresses in the mode in which ODT is operating, not the physical addresses used with console ODT.

"Leadership Team." Datalight. Retrieved 2010-08-23. Datalight's initial products were two DOS applications: the Datalight Small-C compiler and the Datalight C-Bug debugger.

DAVE (Digital Application Virtual Engineer) is an Eclipse-based software platform designed especially to reduce the software development effort and development time required for this. DAVE includes a GNU - compiler, a Debugger, and a visualization utility for graphic presentation of data. Other standard compiler and debugger can be added to the development environment. With pre-defined, tested applications, DAVE also supports automatic code generation.

After debugging the program can be recompiled without debugging information to reduce its size. Later Turbo Debugger, the stand-alone Turbo Assembler (TASM), and Turbo Profiler were included with the compilers in the professional Borland Pascal and Borland C++ versions of the more restricted Turbo Pascal and Turbo C++ suites for DOS. After the popularity of Microsoft Windows ended the era of DOS software development, Turbo Debugger was bundled with TASM for low-level software development. For many years after the end of the DOS era, Borland supplied Turbo Debugger with the last console-mode Borland C++ application development environment, version 5, and with Turbo Assembler 5.0.

The Intel Debugger (IDB) was developed by Intel and provides support (at various levels depending on compiler product) for debugging programs written in C, C++, and Fortran (77, 90 and 95). It provided a choice of command-line and Java-based graphical user interface (GUI) on the Linux Eclipse platform. The Intel Debugger was a component of a number of Intel software products, such as Intel Parallel Studio and their C++ and Fortran compiler products; it supported parallel architectures including MPI, OpenMP, and Pthreads. Support for the Intel Debugger has been deprecated — in the Intel Fortran Composer 2013 product — with the last released version being 13.0.

Next, if a kernel debugger is connected and active when the bug check occurs, the system will break into the debugger where the cause of the crash can be investigated. If no debugger is attached, then a blue text screen is displayed that contains information about why the error occurred, which is commonly known as a blue screen or bug check screen. The user will only see the blue screen if the system is not configured to Automatically Restart (which became the default setting in Windows XP SP2). Otherwise, it appears as though the system simply rebooted (though a blue screen may be visible briefly).

Visual Studio includes a code editor supporting IntelliSense (the code completion component) as well as code refactoring. The integrated debugger works both as a source-level debugger and a machine-level debugger. Other built-in tools include a code profiler, designer for building GUI applications, web designer, class designer, and database schema designer. It accepts plug-ins that expand the functionality at almost every level—including adding support for source control systems (like Subversion and Git) and adding new toolsets like editors and visual designers for domain- specific languages or toolsets for other aspects of the software development lifecycle (like the Azure DevOps client: Team Explorer).

SHAZAM Professional Edition (SHAZAMP) adds menu and wizard driven facilities for executing SHAZAM techniques, a data connector with SQL editor as well as an integrated debugger.

As discussed by Gait,J. Gait (1985). A debugger for concurrent programs. Software-Practice And Experience, 15(6) when an object is monitored, its behavior is changed.

Box-drawing characters made the production of rudimentary graphics practical for early PC game titles, including BBS door games or titles such as Castle Adventure Another use for the MDA was as a secondary display for debugging. Applications like SoftICE and the Windows debugger permitted the simultaneous use of an MDA and another graphics card, with the MDA displaying a debugger interface while the other card was showing the primary display.

This speeds up testing by avoiding running unnecessary test cases. Visual Studio Ultimate 2010 also includes a historical debugger for managed code called IntelliTrace. Unlike a traditional debugger that records only the currently active stack, IntelliTrace records all events, such as prior function calls, method parameters, events and exceptions. This allows the code execution to be rewound in case a breakpoint was not set where the error occurred.

The monitor serves as a debugger, allowing an entire program or individual functions to be run, memory to be displayed and modified, and program execution to be traced.

Wow6432exts is a standard Windows Debugger extension that ships with WinDBG. It is used to debug processes running inside WoW64 (32-bit processes running in 64-bit Windows).

SDB is a minimal debugger, that can only debug C programs compiled in COFF format with debug options. The later version (1988) was capable of reading DWARF debugging information.

Aggarwal and Kumar, pp. 307-312. Early microcomputers with disk-based storage often benefitted from the ability to diagnose and recover corrupted directory or registry data records, to "undelete" files marked as deleted, or to crack file password protection. Most mainstream debugging engines, such as gdb and dbx, provide console-based command line interfaces. Debugger front- ends are popular extensions to debugger engines that provide IDE integration, program animation, and visualization features.

The VMS Debugger supports all DEC compilers and many third party languages. It allows breakpoints, watchpoints and interactive runtime program debugging either using a command line or graphical user interface.

The GCC Summit has been replaced by the GNU Tools Cauldron, a conference held by GNU mainly focused on GNU Compiler Collection (GCC), but also GNU Debugger, GNU Binutils, and others.

OVPsim comes with a GDB RSP (Remote Serial Protocol) interface to allow applications running on simulated processors to be debugged with any standard debugger that supports this GDB RSP interface. OVPsim comes with the Imperas iGui Graphical Debugger and also an Eclipse IDE and CDT interface. OVPsim can be encapsulated and called from within other simulation environments and comes as standard with interface files for C, C++, and SystemC. OVPsim includes native SystemC TLM2.0 interface files.

Stallman popularized the concept of copyleft, a legal mechanism to protect the modification and redistribution rights for free software. It was first implemented in the GNU Emacs General Public License, and in 1989 the first program-independent GNU General Public License (GPL) was released. By then, much of the GNU system had been completed. Stallman was responsible for contributing many necessary tools, including a text editor (Emacs), compiler (GCC), debugger (GNU Debugger), and a build automator (GNU make).

Also, code can be run through a debugger and its data inspected. Dotfuscator can make all of these things more difficult. Dotfuscator was developed by PreEmptive Solutions. A free version of the .

The LPC3100 series are based on the ARM926EJ-S processor core.LPC3100 Series; NXP Semiconductors. The LPC3154 is used by NXP to implement the LPC-Link debugger on all LPCXpresso boards.LPC3152/LPC3154 Datasheet; NXP.

The core of the Holos Server was a business intelligence (BI) virtual machine. The Holos Language (HL), used to drive server-side applications, was compiled into a soft instruction code and executed in this virtual machine (similar in concept to Java in more modern systems). The virtual machine was fully fault- tolerant, using structured exception handling internally, and provided a debugger interface. The debugger was virtual-machine-level until quite late on, after which it also supported source-level access.

SoftICE is a kernel mode debugger for DOS and Windows up to Windows XP. Crucially, it is designed to run underneath Windows such that the operating system is unaware of its presence. Unlike an application debugger, SoftICE is capable of suspending all operations in Windows when instructed. For driver debugging this is critical due to how hardware is accessed and the kernel of the operating system functions. Because of its low-level capabilities, SoftICE is also popular as a software cracking tool.

Micro Focus UFT uses VBScript as its scripting language. VBScript supports classes but not polymorphism and inheritance. Compared with Visual Basic for Applications (VBA), VBScript lacks the ability to use some Visual Basic keywords, does not come with an integrated debugger, lacks an event handler, and does not have a forms editor. HP added a debugger, but the functionality is more limited when compared with testing tools that integrate a full-featured IDE, such as those provided with VBA, Java, or VB.NET.

Its designers considered a non-preemptive multitasking model, but later chose a preemptive (run until blocked) system based on monitors. Pilot included a debugger, Co-Pilot, that could debug a frozen snapshot of the operating system, written to disk. A typical Pilot workstation ran 3 operating systems at once on 3 different disk volumes : Co-Co-Pilot (a backup debugger in case the main operating system crashed), Co-Pilot (the main operating system, running under Co-Co-Pilot and used to compile and bind programs) and an inferior copy of Pilot running in a 3rd disk volume, that could be booted to run test programs (that might crash the main development environment). The debugger was written to read and write variables for a program stored on a separate disk volume.

Stephen Bourne subsequently reused ALGOL 68's `_if_ ~ _then_ ~ _else_ ~ _fi_`, `_case_ ~ _in_ ~ _out_ ~ _esac_` and `_for_ ~ _while_ ~ _do_ ~ _od_` clauses in the common Unix Bourne shell, but with `_in_`'s syntax changed, `_out_` removed, and `_od_` replaced with `_done_` (to avoid conflict with the od utility). After Cambridge, Bourne spent nine years at Bell Labs with the Version 7 Unix (Seventh Edition Unix) team. As well as developing the Bourne shell, he ported ALGOL 68C to Unix on the DEC PDP-11-45 and included a special option in his Unix debugger Advanced Debugger (adb) to obtain a stack backtrace for programs written in ALGOL 68C. Here is an extract from the Unix 7th edition manual pages: NAME adb - debugger SYNOPSIS adb [-w] [ objfil [ corfil ] ] [...] COMMANDS [...] $modifier Miscellaneous commands.

The free software GNU tools (GNU Compiler Collection (GCC), GNU Debugger (GDB), and GNU make) are available on many platforms, including Windows."Use Emacs with Microsoft Visual C++ ... use Emacs as an IDE" The pervasive Unix philosophy of "everything is a text stream" enables developers who favor command-line oriented tools to use editors with support for many of the standard Unix and GNU build tools, building an IDE with programs like Emacs"Emacs: the Free Software IDE""Using Emacs as a Lisp IDE""Emacs as a Perl IDE" or Vim. Data Display Debugger is intended to be an advanced graphical front-end for many text-based debugger standard tools. Some programmers prefer managing makefiles and their derivatives to the similar code building tools included in a full IDE.

Dr. Memory is an open-source memory debugger built on DynamoRIO and released under an LGPL license.Dr. Memory: Memory Debugger for Windows and Linux Dr. Memory monitors memory allocations and memory accesses using shadow memory. It detects memory-related programming errors such as accesses of uninitialized memory, accesses to freed memory, heap overflow and underflow, and memory leaks. Its feature set is similar to that of the Valgrind-based Memcheck tool, though it operates on Windows as well as Linux and is twice as fast as Memcheck.

Some of the most capable and popular debuggers implement only a simple command line interface (CLI)—often to maximize portability and minimize resource consumption. Developers typically consider debugging via a graphical user interface (GUI) easier and more productive. This is the reason for visual front-ends, that allow users to monitor and control subservient CLI-only debuggers via graphical user interface. Some GUI debugger front-ends are designed to be compatible with a variety of CLI-only debuggers, while others are targeted at one specific debugger.

WinDbg is a multipurpose debugger for the Microsoft Windows computer operating system, distributed by Microsoft. Debugging is the process of finding and resolving errors in a system; in computing it also includes exploring the internal operation of software as a help to development. It can be used to debug user mode applications, device drivers, and the operating system itself in kernel mode. Like the better-known Visual Studio Debugger it has a graphical user interface (GUI), but is more powerful and has little else in common.

The mdb project was started in 1997 by Mike Shapiro and others when the Solaris operating system was adding support for 64-bit architectures. Up until that point, Solaris was using the aging adb debugger developed by Steve Bourne (initially for the AT&T; SVR4 Unix distribution). It was very difficult to simply port adb from a 32-bit architecture to a 64-bit architecture, so Sun engineers decided to make a new debugger that would feature enhanced debugging capabilities, while being backward compatible with adb.

There is a preliminary specification for RISC-V's hardware-assisted debugger. The debugger will use a transport system such as Joint Test Action Group (JTAG) or Universal Serial Bus (USB) to access debug registers. A standard hardware debug interface may support either a standardized abstract interface or instruction feeding. , the exact form of the abstract interface remains undefined, but proposals include a memory mapped system with standardized addresses for the registers of debug devices or a command register and a data register accessible to the communication system.

The term debugger can also refer to the person who is doing the debugging. Generally, high-level programming languages, such as Java, make debugging easier, because they have features such as exception handling and type checking that make real sources of erratic behaviour easier to spot. In programming languages such as C or assembly, bugs may cause silent problems such as memory corruption, and it is often difficult to see where the initial problem happened. In those cases, memory debugger tools may be needed.

Virtual Pascal is a free 32-bit Pascal compiler, IDE, and debugger for OS/2 and Microsoft Windows, with some limited Linux support. Virtual Pascal was developed by Vitaly Miryanov and later maintained by Allan Mertner.

Retrieved on 17 September 2015. Built using open-spirce Apache Cordova"Apache Cordova Tools List". Retrieved on 16 October2015. (formerly known as PhoneGap), it provides resources including Cloud IDE, local development tools, a debugger, and backend support.

Because all 8000+ machines in the Xerox corporate Intranet ran the Wildflower architecture (designed by Butler Lampson), there was a remote-debug protocol for microcode. Basically, a peek and poke function could halt and manipulate the microcode state of a C-series or D-series machine, anywhere on earth, and then restart the machine. Also, there was a remote debug protocol for the world-swap debugger. This protocol could, via the debugger "nub", freeze a workstation and then peek and poke various parts of memory, change variables, and continue execution.

The resulting memory dump file may be debugged later, using a kernel debugger. For Windows WinDBG or KD debuggers from Debugging Tools for Windows are used. A debugger is necessary to obtain a stack trace, and may be required to ascertain the true cause of the problem; as the information on-screen is limited and thus possibly misleading, it may hide the true source of the error. By default, Windows XP is configured to save only a 64kB minidump when it encounters a stop error, and to then automatically reboot the computer.

A third-party debugger can also be used in place of Dr. Watson. The Watcom C Compiler includes a similar crash-analysis tool named "Dr. Watcom". Beginning with Windows XP, Dr. Watson (drwtsn32.exe) was extended with (dwwin.

FusionDebug an interactive step debugger for CFML, compatible with Adobe ColdFusion, Railo and Lucee. It enables developers to step through code line- by-line, step into, over or out of code to better understand how code is running.

Also, Digital Research's SID86, the symbolic instruction debugger that shipped with DR DOS 3.xx and provided dedicated functions to debug GEM applications (see `?Y` GEM-specific help under SID86 or GEMSID), could be used for ViewMAX as well.

PragmaDev Specifier embeds an SDL simulator that behaves like a model debugger. It is possible to set breakpoints graphically, to view variables, and pending timers. During execution a live trace is generated based on the Message Sequence Chart ITU-T standard.

On macOS, the following command launches the command "prog" with the shared library from file "test.dylib" linked into it at the launchtime: DYLD_INSERT_LIBRARIES="./test.dylib" DYLD_FORCE_FLAT_NAMESPACE=1 prog It is also possible to use debugger-based techniques on Unix-like systems.

The MPLAB ICD 3 The MPLAB ICD 3 is an in-circuit debugger and programmer by Microchip, and is the latest in the ICD series.MPLAB ICD 3 In-Circuit Debugger, Microchip The ICD 3 connects to the engineer's PC via USB, and connects to the device via ICSP. The ICD 3 is entirely USB-bus-powered, and is 15x faster than the ICD 2 for programming devices. The ICD 3 supports all current PIC and dsPIC devices within the PIC10, PIC12, PIC16, PIC18, dsPIC, rfPIC and PIC32 families, and supports full speed execution, or single step interactive debugging.

This can also provide a serial console through which the in-kernel debugger can be dropped to in case of kernel panics, in which case the local monitor and keyboard may not be usable anymore (the GUI reserves those resources and dropping to the debugger in the case of a panic won't free them). Another context where these cables can be useful is when administering "headless" devices providing a serial administration console (i.e. managed switches, rackmount server units, and various embedded systems). An example of embedded systems that widely use null modems for remote monitoring include RTUs, device controllers, and smart sensing devices.

For cases where the relatively simple debugging facilities of the IDE were insufficient, Turbopower Software produced a more powerful debugger, T-Debug. The same company produced Turbo Analyst and Overlay Manager for Turbo Pascal. T-Debug was later updated for Turbo Pascal 4, but discontinued with the release of Borland's Turbo Debugger (TD), which also allowed some hardware intervention on computers equipped with the new 80386 processor. TD was usually supplied in conjunction with the Turbo Assembler and the Turbo Profiler, a code profiler that reported on the time spent in each part of the program to assist program optimisation by finding bottlenecks.

Early versions of Digital Research's CP/M and CP/M-86 kept the DEC name DDT (and DDT-86 and DDT-68K) for their debugger, however, now meaning "Dynamic Debugging Tool". The CP/M DDT was later superseded by the Symbolic Instruction Debugger (SID, ZSID, SID86, and GEMSID) in DR DOS and GEM. In addition to its normal function as a debugger, DDT was also used as a top- level command shell for the Massachusetts Institute of Technology (MIT) Incompatible Timesharing System (ITS) operating system; on some more recent ITS systems, it is replaced with a "PWORD" which implements a restricted subset of DDT's functionality. DDT could run and debug up to eight processes (called "jobs" on ITS) at a time, such as several sessions of TECO, and DDT could be run recursively - that is, some or all of those jobs could themselves be DDTs (which could then run another eight jobs, and so on).

The Maxine VM is characterized internally by aggressive use of advanced language features in Java 1.5 and 1.6, by modular subsystems coordinated through Java interfaces, by the absence of an interpreter, and by a tightly coupled debugger and visualization tool for VM development.

IPIs are given an IRQL of 29.

There are many inherent limitations to this method. It applies only to C++, and cannot catch memory leaks by C functions like malloc. However, it can be very simple to use and also very fast, when compared to some more complete memory debugger solutions.

Xcode 1.0 was released in fall 2003. Xcode 1.0 was based on Project Builder, but had an updated user interface (UI), ZeroLink, Fix & Continue, distributed build support, and Code Sense indexing. The next significant release, Xcode 1.5, had better code completion and an improved debugger.

Kodos is a FLOSS (GNU GPL) regular expression debugger written in Python, developed by Phil Schwartz. Because Python conforms to the Perl Compatible Regular Expressions standard for its regular expressions, Kodos can be used for debugging regular expressions for any other language that conforms.

It can either step into functions to debug inside it, or step over it, i.e., the execution of the function body isn't available for manual inspection. The debugger supports Edit and Continue, i.e., it allows code to be edited as it is being debugged.

The player is assisted by a fellow debugger named Leon who provides information and weapons and is also said player's buddy. The game featured a minimal ability to look up and down. Selecting a higher difficulty generated a blobby monster that moved on the ceiling.

For embedded computers, it may be impractical to support debugging on the computer itself, so analysis of a dump may take place on a different computer. Some operating systems such as early versions of Unix did not support attaching debuggers to running processes, so core dumps were necessary to run a debugger on a process's memory contents. Core dumps can be used to capture data freed during dynamic memory allocation and may thus be used to retrieve information from a program that is no longer running. In the absence of an interactive debugger, the core dump may be used by an assiduous programmer to determine the error from direct examination.

This eases the burden of debugging problems that have various versions of binaries installed on the debugging target by eliminating the need for finding and installing specific symbols version on the debug host. Microsoft has a public symbol server that has most of the public symbols for Windows 2000 and later versions of Windows (including service packs). Recent versions of WinDbg have been and are being distributed as part of the free Debugging Tools for Windows suite, which shares a common debugging back-end between WinDbg and command line debugger front-ends like KD, CDB, and NTSD. Most commands can be used as is with all the included debugger front-ends.

The set of core tools has continued to expand, now including a REPL, package manager, time-traveling debugger, and installers for macOS and Windows. Elm also has an ecosystem of community created libraries and an advanced online editor that allows saved work and inclusion of community libraries.

The JVMTI replaces the JVMPI (Java Virtual Machine Profiling Interface) and the JVMDI (Java Virtual Machine Debug Interface). The JVMPI and the JVMDI are declared as being deprecated in J2SE 5.0 and were removed in Java SE6. JVMTI is the lowest level of the Java Platform Debugger Architecture.

Extensible programming systems must support the debugging of programs using the constructs of the original source language regardless of the extensions or transformation the program has undergone in order to make it executable. Most notably, it cannot be assumed that the only way to display runtime data is in structures or arrays. The debugger, or more correctly 'program inspector', must permit the display of runtime data in forms suitable to the source language. For example, if the language supports a data structure for a business process or work flow, it must be possible for the debugger to display that data structure as a fishbone chart or other form provided by a plugin.

A complete implementation of the Java platform also needs a compiler that translates Java source code into bytecodes, a program that manages JAR files, a debugger, and an applet viewer and web browser plugin, to name a few. Harmony has the compiler, appletviewer, jarsigner, javah, javap, keytool, policytool, and unpack200.

It also contains a secure command line FTP Client program called sysaxftp.exe that is a secure drop-in replacement for the ftp.

Some debuggers operate on a single specific language while others can handle multiple languages transparently. For example, if the main target program is written in COBOL but calls assembly language subroutines and PL/1 subroutines, the debugger may have to dynamically switch modes to accommodate the changes in language as they occur.

Firebug's script tab enables users to set breakpoints and step through lines of code. Additionally, Firebug can navigate directly to a line of JavaScript code, watch expressions, call stacks, and launch the debugger in the event an error occurs during execution. Firebug can also log errors. Logging uses a Firebug JavaScript API.

PurifyPlus is a memory debugger program used by software developers to detect memory access errors in programs, especially those written in C or C++. It was originally written by Reed Hastings of Pure Software.Purify: fast detection of memory leaks and access errors. by Reed Hastings and Bob Joyce, Usenix Winter 1992 technical conference.

Record and replay debugging is the process of recording the execution of a software program so that it may be played back within a debugger to help diagnose and resolve defects. The concept is analogous to the use of a flight data recorder to diagnose the cause of an airplane flight malfunction.

In the define-by-run approach, you can just suspend the calculation with the language's built-in debugger and inspect the data that flows on your code of the network. Define-by-run has gained popularity since the introduction by Chainer and is now implemented in many other frameworks, including PyTorch and TensorFlow.

In some cases, variants may instead modify the registry to install the malicious payload as a debugger for the benign system file ctfmon.exe so that ctfmon.exe executes on system startup, which leads to the execution of the malware. In most cases, Slenfbot will attempt to delete the original copy of the worm.

The Small Device C Compiler (SDCC) is a free-software, partially retargetableRainer Leupers, Peter Marwedel: "Retargetable Compiler Technology for Embedded Systems: Tools and Applications", page 126. Springer, 2001 C compiler for 8-bit microcontrollers. It is distributed under the GNU General Public License. The package also contains a linker, assembler, simulator and debugger.

Programs known as debuggers help programmers locate bugs by executing code line by line, watching variable values, and other features to observe program behavior. Without a debugger, code may be added so that messages or values may be written to a console or to a window or log file to trace program execution or show values. However, even with the aid of a debugger, locating bugs is something of an art. It is not uncommon for a bug in one section of a program to cause failures in a completely different section, thus making it especially difficult to track (for example, an error in a graphics rendering routine causing a file I/O routine to fail), in an apparently unrelated part of the system.

In 1987 Kardakov worked as an engineer-debugger of CSESS (Kyiv). In 1990 he cofounded Information Computer Systems (ICS) where worked as CTO. The company develops software and automation hardware in the electronics industry. Kardakov subsequently became a CEO of ICS in 1996, and in 2019 he founded ICS- Megatrade and Best Power Ukraine.

QBasic has limited support for user-defined data types (structures), and several primitive types used to contain strings of text or numeric data. It supports various inbuilt functions. For its time, QBasic provided a state-of-the-art IDE, including a debugger with features such as on-the-fly expression evaluation and code modification.

The debugger can compute the value of a variable in the source program from the state of the concrete machine by using information stored by the compiler. Memory debuggers can directly point out questionable or outright wrong memory accesses of running programs which may otherwise remain undetected and are a common source of program failures.

Digitized voices were used for the game's opening credits and victory screen. According to the game's end credits: > This game was written in 100% assembly and takes up more than 35,000 lines. > The game contains approximately 20,000 3D objects. It was developed using > Turbo Assembler and Turbo Debugger with all debugging being done remotely.

Watson also influenced the creation of other fictional narrators, such as Bunny Manders (the sidekick of gentleman thief A. J. Raffles, created by E. W. Hornung in 1898) and the American character Archie Goodwin (the assistant of detective Nero Wolfe, created by Rex Stout in 1934). Microsoft named the debugger in Microsoft Windows "Dr. Watson".

BASIC/WS ran stand-alone. It provided operating system (OS), integrated development environment (editor and debugger), and the language interpreter. Later, HP implemented RMB on top of the HP-UX operating system, and called it "BASIC/UX". BASIC/UX 300 ran on series 300 hardware and BASIC/UX 700 ran on series 700 hardware.

For performance reasons, in 1992 and 1993 SK8 was re-implemented from the ground up. Working at Apple's Cambridge Research Center, the Macintosh Common Lisp object store was isolated and directly hooked into SK8's store. The SK8Script debugger was re- implemented at the assembler language level (previously in Lisp) and the compiler and runtime performance improved.

Central to the SN Systems product line is the ProDG suite, comprising a compiler and integration with Microsoft Visual Studio, together with a debugger and additional build tools. SN Systems now may include its own SNC compiler with ProDG, rather than a derivative of the compiler provided by the console manufacturer (frequently a variant of GNU Compiler Collection).

GDB was first written by Richard Stallman in 1986 as part of his GNU system, after his GNU Emacs was "reasonably stable". GDB is free software released under the GNU General Public License (GPL). It was modeled after the DBX debugger, which came with Berkeley Unix distributions. From 1990 to 1993 it was maintained by John Gilmore.

The Sx-Key is produced by Parallax and used to program the SX microcontroller and then debug it. There is also a cheaper version called the SX-Blitz that does not contain a debugger. Do note that there are two Sx-key products, one is an actual hardware device the other is the software, they share the same name.

The jdbgmgr.exe virus hoax involved an e-mail spam in 2002 that advised computer users to delete a file named jdbgmgr.exe because it was a computer virus. jdbgmgr.exe, which had a little teddy bear like icon (The Microsoft Bear), was actually a valid Microsoft Windows file, the Debugger Registrar for Java (also known as Java Debug Manager, hence jdbgmgr).

Microsoft Visual InterDev, part of Microsoft Visual Studio 97 and 6.0, is an IDE used to create web applications using Microsoft Active Server Pages (ASP) technologies.

The extensive InterDev IDE is shared with Microsoft Visual J++, and is the precursor to the Visual Studio .NET IDE.

The Silicon Labs Integrated Development Environment (IDE) is a complete, stand-alone software program that includes a project manager, source editor, source-level debugger and other utilities. The IDE interfaces to third party development tool chains to provide system designers a complete embedded software development environment. The IDE supports the entire 8-bit microcontroller (MCU) portfolio.

Another strategy, when suspecting a small set of classes, is to temporarily make all their member functions virtual: after the class instance has been destructed/freed, its pointer to the Virtual Method Table is set to `NULL`, and any call to a member function will crash the program and it will show the guilty code in the debugger.

Researchers Daniel Jackson and Joseph Near developed a data debugger they called "Space" that can analyze the data access of a Rails program and determine if the program properly adheres to rules regarding access restrictions. On April 15, 2016, Near reported that an analysis of 50 popular Web applications using Space uncovered 23 previously unknown security flaws.

SDB is a symbolic debugger for C programs. It may be used to examine their files and to provide a controlled environment for their execution. SDB was first introduced in UNIX/32V. The authors(s) of the original version are unknown, but a second version was created from scratch in 1988 by Brian Russell and David Weatherford.

NET Reflector 6 along with a commercial Pro edition that enabled users to step into decompiled code in the Visual Studio debugger as if it were their own source code. On 10 January 2011 Red Gate announced that .NET Reflector 7 would incorporate Jason Haley's PowerCommands add-in. On 1 February 2011 Red Gate announced that .

Serial Wire Debug (SWD) is an alternative 2-pin electrical interface that uses the same protocol. It uses the existing GND connection. SWD uses an ARM CPU standard bi-directional wire protocol, defined in the ARM Debug Interface v5. This enables the debugger to become another AMBA bus master for access to system memory and peripheral or debug registers.

Rhino converts JavaScript scripts into classes. Rhino works in both compiled and interpreted mode. It is intended to be used in desktop or server-side applications, hence there is no built-in support for the Web browser objects that are commonly associated with JavaScript. Rhino can be used as a debugger by using the Rhino shell.

Visual Studio supports 36 different programming languages and allows the code editor and debugger to support (to varying degrees) nearly any programming language, provided a language-specific service exists. Built-in languages include C, C++, C++/CLI, Visual Basic .NET, C#, F#, JavaScript, TypeScript, XML, XSLT, HTML, and CSS. Support for other languages such as Python, Ruby, Node.

The debugger allows setting breakpoints (which allow execution to be stopped temporarily at a certain position) and watches (which monitor the values of variables as the execution progresses). Breakpoints can be conditional, meaning they get triggered when the condition is met. Code can be stepped over, i.e., run one line (of source code) at a time.

When debugging, if the mouse pointer hovers over any variable, its current value is displayed in a tooltip ("data tooltips"), where it can also be modified if desired. During coding, the Visual Studio debugger lets certain functions be invoked manually from the `Immediate` tool window. The parameters to the method are supplied at the Immediate window.

The MTS job program is always executing one of several command language subsystems or CLSs. Many of the MTS commands are built into MTS and execute as part of the MTS CLS. User programs execute as the USER CLS. The USER CLS has a special relationship to the Symbolic Debugging System (SDS CLS) when the debugger is active.

DenyHosts is a log-based intrusion-prevention security tool for SSH servers written in Python. It is intended to prevent brute-force attacks on SSH servers by monitoring invalid login attempts in the authentication log and blocking the originating IP addresses. DenyHosts is developed by Phil Schwartz, who is also the developer of Kodos Python Regular Expression Debugger.

Many of the BSDL definitions are sets of single long string constants. Note that registers not involved in boundary scan are often not defined. Instructions that are not publicly defined are included in the INSTRUCTION_PRIVATE section. Microprocessor register descriptions in BSDL typically do not include enough information to aid in building a 1149.1 based emulator or debugger.

Once the bug is reproducible, the programmer may use a debugger or other tool while reproducing the error to find the point at which the program went astray. Some bugs are revealed by inputs that may be difficult for the programmer to re-create. One cause of the Therac-25 radiation machine deaths was a bug (specifically, a race condition) that occurred only when the machine operator very rapidly entered a treatment plan; it took days of practice to become able to do this, so the bug did not manifest in testing or when the manufacturer attempted to duplicate it. Other bugs may stop occurring whenever the setup is augmented to help find the bug, such as running the program with a debugger; these are called heisenbugs (humorously named after the Heisenberg uncertainty principle).

Concurrent applications should execute correctly on every possible thread schedule in the underlying operating system. However, traditional testing methods detect few bugs, chiefly because of the Heisenbugs problem. A Heisenbug is an error that changes or disappears when an attempt is made to isolate and probe them via debugger, by adding some constructs such as synchronization requests or delay statements.

Logtalk features on-line help, a documenting tool (that can generate PDF and HTML files), an entity diagram generator tool, a built-in debugger (based on an extended version of the traditional Procedure Box model found on most Prolog compilers), a unit test framework with code coverage analysis, and is also compatible with selected back-end Prolog profilers and graphical tracers.

MAC/65 is 6502 editor/assembler originally released on disk in 1982, then on a bank-switched "supercartridge" in 1983 which included an integrated debugger (DDT).

Heisenbugs occur because common attempts to debug a program, such as inserting output statements or running it with a debugger, usually have the side-effect of altering the behavior of the program in subtle ways, such as changing the memory addresses of variables and the timing of its execution. One common example of a heisenbug is a bug that appears when the program is compiled with an optimizing compiler, but not when the same program is compiled without optimization (as is often done for the purpose of examining it with a debugger). While debugging, values that an optimized program would normally keep in registers are often pushed to main memory. This may affect, for instance, the result of floating-point comparisons, since the value in memory may have smaller range and accuracy than the value in the register.

Xcode 4.3.1 was released on March 7, 2012 to add support for iOS 5.1.

Smile is free, and primarily designed for AppleScript development. SmileLab is commercial software with extensive additions for numerical analysis, graphing, machine automation and web production.

A race condition can be difficult to reproduce and debug because the end result is nondeterministic and depends on the relative timing between interfering threads. Problems of this nature can therefore disappear when running in debug mode, adding extra logging, or attaching a debugger. Bugs that disappear like this during debugging attempts are often referred to as a "Heisenbug". It is therefore better to avoid race conditions by careful software design.

The system contained a number of enhancements, notably tools to access DOS files directly on a DOS/FAT-partition, and an updated ADB debugger. The system came in two flavors: a 2-user version priced at $800, and an 8-user version at $1,000. There were no technical differences between the two. Confusingly, Venix 2.0 for the DEC PRO-380 microcomputer (Venix/PRO) was based "essentially" on System III.

There are many techniques that can be utilized to verify a model. These include, but are not limited to, having the model checked by an expert, making logic flow diagrams that include each logically possible action, examining the model output for reasonableness under a variety of settings of the input parameters, and using an interactive debugger. Many software engineering techniques used for software verification are applicable to simulation model verification.

The debug status register permits the debugger to determine which debug conditions have occurred. When the processor detects an enabled debug exception, it sets the low-order bits of this register (0,1,2,3) before entering the debug exception handler. Note that the bits of DR6 are never cleared by the processor. To avoid any confusion in identifying the next debug exception, the debug handler should move zeros to DR6 immediately before returning.

As a relatively new operating system, rapid progress is being made in its development. Some of its features currently include an integrated development environment, a visual debugger, a web browser with a JavaScript engine, and a graphically oriented desktop shell.

In SMM mode, the RSM instruction is used to load a full CPU state from a memory area. The layout of this memory area is similar to one used by the LOADALL instruction. 386-style LOADALL instruction can be executed on 486 too, but only in SMM mode. In later processors, RSM instruction, with a different encoding, took its role. Microsoft's Codeview 3.0 and Borland's Turbo Debugger 2.0 correctly decode 286 and 386 LOADALL instructions.

Brackets integrates Theseus, an open-source JavaScript debugger that enables developers to set break points, step through code, and inspect the value of variables in real time. Theseus can be used to debug any extension in Brackets and is easily installed using the built-in extension manager. Theseus also works in conjunction with Live Preview through a proxy server that records a function and its associated values every time the function is called.

A major advantage of the GraalVM ecosystem is language-agnostic, fully dynamic instrumentation support built-in directly into the VM runtime. Execution events can be captured by API clients with overhead that is extremely low in fully optimized code. The core GraalVM installation provides a language- agnostic debugger, profiler, heap viewer, and others based on instrumentation and other VM support. GraalVM also includes a backend implementation of the Chrome Inspector remote debugging protocol.

Anjuta is an IDE for C and C++ programming in the GNOME desktop environment. An integrated development environment (IDE) is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of at least a source code editor, build automation tools and a debugger. Some IDEs, such as NetBeans and Eclipse, contain the necessary compiler, interpreter, or both; others, such as SharpDevelop and Lazarus, do not.

The Atari Macro Assembler was offered by Atari to provide better performance and more powerful features, such as macros, but it was disk-based, copy-protected, and did not include an editor or debugger. Despite the recommendation, commercial software was written using the Assembler Editor, such as the games Eastern Front (1941) and Galahad and the Holy Grail. The source code to the original Assembler Editor was licensed to Optimized Systems Software who shipped EASMD based on it.

Quanta Plus, originally called Quanta, is a web Integrated development environment (IDE) for HTML, XHTML, CSS, XML, PHP and any other XML-based languages or scripting languages. Quanta was licensed under GPL before the release of version 2.0 final. Quanta is capable of both WYSIWYG design and handcoding. It features tag completion on the fly, tag editing through a dialog interface, script language variable auto-completion, project management, live preview, PHP debugger, CVS support, Subversion support (through external plugin).

Memory allocation routines fill guard bytes with values that are not supposed to be used by the programmer's algorithms. This is, however, not predictable. When the algorithm uses those values and overwrites the guard bytes with them (only the last write before deallocation is relevant), the overflow can not be detected, because the bytes have not actually changed. Instead, the memory breakpoint option can be used, set on a condition of access to those bytes in a debugger.

This was first applied to system time counter updating. Each time interrupt updates the time of the day; there may be many readers of the time for operating system internal use and applications, but writes are relatively infrequent and only occur one at a time. The BSD timecounter code for instance appears to use a similar technique. One subtle issue of using seqlocks for a time counter is that it is impossible to step through it with a debugger.

A simple Filemaker script that flags duplicate entries in a list of names. FileMaker Pro and FileMaker Pro Advanced include scripting capabilities and a variety of built-in functions for automation of common tasks and complex calculations. Numerous steps are available for navigation, conditional execution of script steps, editing records, and other utilities. FileMaker Pro Advanced provides a script debugger which allows the developer to set break points, monitor data values and step through script lines.

It can create both 2D and 3D games by providing function libraries that enable a game to be programmed with considerably less code than with a language such as C++, especially without such dedicated libraries. The software consists of an IDE, debugger and interpreter, and an engine built on DirectX 7. The compiler emits Bytecode that is appended to an interpreter to create a stand-alone executable. Star Wraith is an example game made with DarkBASIC.

The Intel compiler provides debugging information that is standard for the common debuggers (DWARF 2 on Linux, similar to gdb, and COFF for Windows). The flags to compile with debugging information are `/Zi` on Windows and `-g` on Linux. Debugging is done on Windows using the Visual Studio debugger and, on Linux, using gdb. While the Intel compiler can generate a gprof compatible profiling output, Intel also provides a kernel level, system-wide statistical profiler called Intel VTune Profiler.

OllyDbg is often used for reverse engineering of programs. It is often used by crackers to crack software made by other developers. For cracking and reverse engineering, it is often the primary tool because of its ease of use and availability; any 32-bit executable can be used by the debugger and edited in bitcode/assembly in realtime. It is also useful for programmers to ensure that their program is running as intended, and for malware analysis purposes.

ARMulator allows runtime debugging using either armsd (ARM Symbolic Debugger), or either of the graphical debuggers that were shipped in SDT and the later ADS products. ARMulator suffered from being an invisible tool with a text file configuration (armul.conf) that many found complex to configure. ARMulator II formed the basis for the high accuracy, cycle callable co-verification models of ARM processors, these CoVs models (see Cycle Accurate Simulator) were the basis of many CoVerification systems for ARM processors.

Following his PhD in 1998, he joined the Computer Science Department at the University of Chicago, and received a National Science Foundation CAREER Awards to investigate the development of mixed-language software tools. He won the Best Paper Award at PyCon 2001 for developing the Wrapped Application Debugger (WAD), which converts fatal exception errors into Python exceptions. In 2005, he left the University to start a consulting company, Dabeaz LLC, to focus on developing Python tools and learning resources.

This was an unorthodox integrated development environment incorporating an editor, compiler, linker and (post-mortem) debugger. The TDS was a transputer application written in occam. The TDS text editor was notable in that it was a folding editor, allowing blocks of code to be hidden and revealed, to make the structure of the code more apparent. Unfortunately, the combination of an unfamiliar programming language and equally unfamiliar development environment did nothing for the early popularity of the transputer.

CodeView is a standalone debugger created by David Norris at Microsoft in 1985 as part of its development toolset. It originally shipped with Microsoft C 4.0 and later. It also shipped with Visual Basic for MS-DOS, Microsoft BASIC PDS, and a number of other Microsoft language products. It was one of the first debuggers on the DOS platform that was full-screen oriented, rather than line- oriented (as Microsoft's predecessors DEBUG and SYMDEB or Digital Research's SID).

According to Kotok, the project was, "digital recording more than 20 years ahead of its time." In 1984, when Jack Dennis asked if they could recognize Beethoven, Computer Museum meeting minutes record the authors as saying, "It wasn't bad, considering." Digital audio pioneer Thomas Stockham worked with Dennis and like Kotok helped develop a contemporary debugger. Whether he was first influenced by Expensive Tape Recorder or more by the work of Kenneth N. Stevens is unknown.

Larry Tesler oversaw the project, which began very early in 1985 and became a product in 1986. An Object Pascal extension was also implemented in the Think Pascal IDE. The IDE includes the compiler and an editor with syntax highlighting and checking, a powerful debugger, and a class library. Many developers preferred Think Pascal over Apple's implementation of Object Pascal because Think Pascal offered a much faster compile–link–debug cycle, and tight integration of its tools.

Phoenix developed customized versions of 86-DOS (or sometimes called PDOS for Phoenix DOS) for various microprocessor platforms. Phoenix also provided PMate as a replacement for Edlin as the DOS file editor. Phoenix also developed C language libraries, called PForCe, along with Plink-86/Plink-86plus, overlay linkers, and Pfix-86, a windowed Debugger for DOS. These products only provided a small revenue stream to Phoenix during the early 1980s and the company did not significantly expand in size.

The SysV Application Binary Interface includes a specification for the format of debug symbols. This allows any compatible compiler or assembler to create debug symbols in a standardized format, and for any debugger, such as GDB, to gain access and display these symbols. For example, part of the important debug information includes the line of code in the source file which defines that symbol (a function or global variable), as well as symbols associated with exception frames.

Microsoft compilers generate a file called a PDB file containing debug symbols. Some companies ship the PDB on their CD/DVD to enable troubleshooting and other companies (like Microsoft, and the Mozilla Corporation) allow downloading debug symbols from the Internet. The WinDBG debugger and the Visual Studio IDE can be configured to automatically download debug symbols for Windows DLLs on demand. The PDB debug symbols that Microsoft distributes include only public functions, global variables and their data types.

Now, LLVM is a brand that applies to the LLVM umbrella project, the LLVM intermediate representation (IR), the LLVM debugger, the LLVM implementation of the C++ Standard Library (with full support of C++11 and C++14), etc. LLVM is administered by the LLVM Foundation. Its president is compiler engineer Tanya Lattner. "For designing and implementing LLVM", the Association for Computing Machinery presented Vikram Adve, Chris Lattner, and Evan Cheng with the 2012 ACM Software System Award.

"Self-awareness", as noted above, is sometimes used by science fiction writers as a name for the essential human property that makes a character fully human. Turing strips away all other properties of human beings and reduces the question to "can a machine be the subject of its own thought?" Can it think about itself? Viewed in this way, a program can be written that can report on its own internal states, such as a debugger.

Cheat Engine (CE) is a free and open-source memory scanner/debugger created by Eric Heijnen ("Dark Byte") for the Windows operating system. Cheat Engine is mostly used for cheating in computer games and is sometimes modified and recompiled to evade detection. The program resembles L. Spiro's Memory Hacking Software, TSearch, and ArtMoney. It searches for values input by the user with a wide variety of options that allow the user to find and sort through the computer's memory.

Examples of commercial solutions come from Green Hills Software, Lauterbach GmbH and Microchip's MPLAB-ICD (for in-circuit debugger). Two examples of research prototype tools are Aveksha and Flocklab. They all leverage a functionality available on low-cost embedded processors, an On-Chip Debug Module (OCDM), whose signals are exposed through a standard JTAG interface. They are benchmarked based on how much change to the application is needed and the rate of events that they can keep up with.

Winpdb debugging itself A debugger or debugging tool is a computer program used to test and debug other programs (the "target" program). The main use of a debugger is to run the target program under controlled conditions that permit the programmer to track its operations in progress and monitor changes in computer resources (most often memory areas used by the target program or the computer's operating system) that may indicate malfunctioning code. Typical debugging facilities include the ability to run or halt the target program at specific points, display the contents of memory, CPU registers or storage devices (such as disk drives), and modify memory or register contents in order to enter selected test data that might be a cause of faulty program execution. The code to be examined might alternatively be running on an instruction set simulator (ISS), a technique that allows great power in its ability to halt when specific conditions are encountered, but which will typically be somewhat slower than executing the code directly on the appropriate (or the same) processor.

The Intel compiler provides debugging information that is standard for the common debuggers (DWARF 2 on Linux, similar to gdb, and COFF for Windows). The flags to compile with debugging information are `/Zi` on Windows and `-g` on Linux. Debugging is done on Windows using the Visual Studio debugger, and on Linux using gdb. While the Intel compiler can generate a gprof-compatible profiling output, Intel also provides a kernel-level, system-wide statistical profiler as a separate product called VTune.

When a program error occurs in Windows, the system searches for a program error handler. A program error handler deals with errors as they arise during the running of a program. If the system does not find a program error handler, the system verifies that the program is not currently being debugged and considers the error to be unhandled. The system then processes unhandled errors by looking in the registry for a program error debugger for which Dr. Watson is the default.

Version 2.0 (late 1988) featured the first "blue screen" version, which would be typical of all future Borland releases for MS-DOS. It was also available bundled with Turbo Assembler and Turbo Debugger. Turbo C 2.0 was also released (in Germany only) for the Atari ST; the program was not maintained by Borland, but sold and renamed PureC. With the release of Turbo C++ 1.0 (in 1990), the two products were folded into one and the name "Turbo C" was discontinued.

Scorpion (), was a very widespread ZX Spectrum clone produced in St. Petersburg, Russia by Sergey Zonov. It had a Z80 processor and from 256 to 1024 KB memory, the Shadow Service Monitor (debugger) in the basic ROM activated by pressing the Magic Button (NMI), a ProfROM with additional included ZX-Word editor, a clock, HDD utilities and more. Various extensions were produced, including SMUC — adapter of IDE and ISA slots, which allowed the use of IBM PC compatible hard drives and extension cards.

The line-oriented debugger `DEBUG` is an external command in operating systems such as DOS, OS/2 and Windows (only in 16-bit/32-bit versions). DEBUG can act as an assembler, disassembler, or hex dump program allowing users to interactively examine memory contents (in assembly language, hexadecimal or ASCII), make changes, and selectively execute COM, EXE and other file types. It also has several subcommands which are used to access specific disk sectors, I/O ports and memory addresses.

ProDG for PSP® was released in 2004, using SNC technology licensed from Apogee. It included the v2.0 debugger, SNC C/C++ Compiler and Tuner as standard. The majority of North American launch titles for Sony Computer Entertainment's PSP® (PlayStation®Portable) were developed using the ProDG suite of tools. From a line-up of 24 game titles listed in the North American launch window for PSP, 20 were developed using SN Systems' ProDG for PSP® development tools.

Powered by the GNU toolchain (GNU Compiler Collection, GNU Debugger), the SDK enables programmers to write, compile, and debug C/C++ applications for their embedded system. Xilinx's tools provides the possibility of running software in simulation, or using a suitable FPGA-board to download and execute on the actual system. Purchasers of Vivado are granted a perpetual license to use MicroBlaze in Xilinx FPGAs with no recurring royalties. The license does not grant the right to use MicroBlaze outside of Xilinx's devices.

In 1967 Knight wrote the original kernel for the ITS operating system, as well as the combination of command processor and debugger that was used as its top-level user interface. ITS was the dominant operating system for first Project MAC and later the MIT Artificial Intelligence Laboratory and MIT Laboratory for Computer Science. ITS ran on PDP-6 and, later, PDP-10 computers. In 1968, Knight designed and supervised the construction of the first PDP-10 ARPANET interfaces with Bob Metcalfe.

WinDbg allows the loading of extension DLLs that can augment the debugger's supported commands and allow for help in debugging specific scenarios: for example, displaying an MSXML document given an IXMLDOMDocument, or debugging the Common Language Runtime (CLR). These extensions are a large part of what makes WinDbg such a powerful debugger. WinDbg is used by the Microsoft Windows product team to build Windows, and everything needed to debug Windows is included in these extension DLLs. Extension commands are always prefixed with !.

A year later, Unknown Worlds released Decoda as a commercial debugger for the Lua programming language. This application was created to aid with development of Natural Selection 2, whose game code was largely being written in Lua. Later on in development of Natural Selection 2, the studio announced it had changed engine from the Source engine to their own proprietary engine developed in-house. After consulting their fanbase on a possible name for their new engine, it was finally named the Evolution engine.

The call stack can sometimes be inspected as the program is running. Depending on how the program is written and compiled, the information on the stack can be used to determine intermediate values and function call traces. This has been used to generate fine-grained automated tests, and in cases like Ruby and Smalltalk, to implement first-class continuations. As an example, the GNU Debugger (GDB) implements interactive inspection of the call stack of a running, but paused, C program.

SWI-Prolog is a free implementation of the programming language Prolog, commonly used for teaching and semantic web applications. It has a rich set of features, libraries for constraint logic programming, multithreading, unit testing, GUI, interfacing to Java, ODBC and others, literate programming, a web server, SGML, RDF, RDFS, developer tools (including an IDE with a GUI debugger and GUI profiler), and extensive documentation. SWI-Prolog runs on Unix, Windows, Macintosh and Linux platforms. SWI-Prolog has been under continuous development since 1987.

In May 2008, a Debian developer discovered that the OpenSSL package distributed with Debian and derivatives such as Ubuntu made a variety of security keys vulnerable to a random number generator attack, since only 32,767 different keys were generated. The security weakness was caused by changes made in 2006 by another Debian developer in response to memory debugger warnings. The complete resolution procedure was cumbersome because patching the security hole was not enough; it involved regenerating all affected keys and certificates.

PurifyPlus also includes other functionality, such as high-performance watchpoints, which are of general use while using a debugger on one's code. It is worth noting that using PurifyPlus makes the most sense in programming languages that leave memory management to the programmer. Hence, in Java, Lisp, or Visual Basic, for example, automatic memory management reduces occurrence of any memory leaks. These languages can however still have leaks; unnecessary references to objects will prevent the memory from being re-allocated.

It is pretty difficult for a data scientist to actually debug an unexpected result. The massive scale and unstructured nature of data, the complexity of these analytics pipelines, and long runtimes pose significant manageability and debugging challenges. Even a single error in these analytics can be extremely difficult to identify and remove. While one may debug them by re-running the entire analytics through a debugger for step-wise debugging, this can be expensive due to the amount of time and resources needed.

Since it features a disassembler and a low-level debugger, radare2 can be useful to developers of exploits. The software has features which assist in exploit development, such as a ROP gadget search engine and mitigation detection. Because of the software's flexibility and support for many file formats, it is often used by capture the flag teamsDragon SectorLSE and other security-oriented personnel.Phrack - manual binary mangling with radare Radare2 can also assist in creating shellcodes with its 'ragg2' tool, similar to metasploit.

In debugging mode, in the Threads window, which lists all the threads, hovering over a thread displays the stack trace of that thread in tooltips. The threads can directly be named and flagged for easier identification from that window itself. In addition, in the code window, along with indicating the location of the currently executing instruction in the current thread, the currently executing instructions in other threads are also pointed out. The Visual Studio debugger supports integrated debugging of the .

Graceful exits are not always desired. In many cases, an outright crash can give the software developer the opportunity to attach a debugger or collect important information, such as a core dump or stack trace, to diagnose the root cause of the error. In a language that supports formal exception handling, a graceful exit may be the final step in the handling of an exception. In other languages graceful exits can be implemented with additional statements at the locations of possible errors.

However, this was ineffective as it was still limited by the native AmigaOS scheduler and it did create extra difficulties synchronising with the 68k side (particularly for sound). In version 15 WarpOS introduced a concept called atomic tasks. Atomic tasks are non-interruptible, and scheduling does not take place unless the task explicitly allows to do so. WarpOS also had an inbuilt debugger which could be sent to dump information on any crashed tasks to either console window on screen or to serial, depending on environment variables.

Bytecode weavers can be deployed during the build process or, if the weave model is per-class, during class loading. AspectJ started with source-level weaving in 2001, delivered a per-class bytecode weaver in 2002, and offered advanced load-time support after the integration of AspectWerkz in 2005. Any solution that combines programs at runtime has to provide views that segregate them properly to maintain the programmer's segregated model. Java's bytecode support for multiple source files enables any debugger to step through a properly woven .

Richard Stallman founded the GNU Project in September 1983 with an aim to create a free GNU operating system. Initially the components required for kernel development were written: editors, shell, compiler, debugger etc. By 1989, the GNU GPL came into being and the only major component missing was the kernel. Development on the Hurd began in 1990 after an abandoned kernel attempt in 1986, based on the research TRIX operating system developed by Professor Steve Ward and his group at MIT's Laboratory for Computer Science (LCS).

In late 1989, Kevin Calhoun, then a HyperCard engineer at Apple, led an effort to upgrade the program. This resulted in HyperCard 2.0, released in 1990. The new version included an on-the-fly compiler that greatly increased performance of computationally intensive code, a new debugger and many improvements to the underlying HyperTalk language. At the same time HyperCard 2.0 was being developed, a separate group within Apple developed and in 1991 released HyperCard IIGS, a version of HyperCard for the Apple IIGS system.

Cheating in video games involves a video game player using various methods to create an advantage beyond normal gameplay, in order to make the game easier. Cheats may be activated from within the game itself (a cheat code implemented by the original game developers), or created by third-party software (a game trainer or debugger) or hardware (a cheat cartridge). They can also be realized by exploiting software bugs; this may or may not be considered cheating based on whether the bug is considered common knowledge.

Key differences are in the memory interface and services, also the instruction decode is done differently. The GNU ARMulator is available as part of the GDB debugger in the ARM GNU Tools. ARMulator II formed the basis for the high accuracy, cycle callable co-verification models of ARM processors, these CoVs models (see Cycle Accurate Simulator) were the basis of many CoVerification systems for ARM processors. Mentor Graphic's Seamless have the market leading CoVs system that supports many ARM cores, and many other CPUs.

Atari's 8-bit line used a button for this same purpose. Debugging NMIs have appeared in a number of forms, including the Apple Macintosh's "programmers' button", and certain key combinations on Sun workstations. With the introduction of Windows 2000, Microsoft allowed the use of an NMI to cause a system to either break into a debugger, or dump the contents of memory to disk and reboot. Debugging NMIs have also been used by devices that allow leisure users and gamers to manipulate running programs.

A separate package, called the Embedded Design Suite (EDS), manages the software development. Based on the Eclipse IDE, the EDS includes a C/C++ compiler (based on the GNU toolchain), debugger, and an instruction-set simulator. EDS allows programmers to test their application in simulation, or download and run their compiled application on the actual FPGA host. Because the C/C++ development-chain is based on GCC, the vast majority of open source software for Linux compiles and runs with minimal or no modification.

MPW supported a source-level debugger called SADE (Symbolic Application Debugging Environment). SADE was not an MPW Tool, but ran as a separate application with a user interface similar to MPW. Apple's compilers had some features that were not common on other platforms--for example, the Pascal compiler was object-oriented, while the C and C++ compilers included support for length-prefixed strings (needed for Pascal-oriented APIs). Pascal was Apple's original preferred language for Macintosh software development, and MPW was initially released with only Pascal support.

PurifyPlus allows dynamic verification, a process by which a program discovers errors that occur when the program runs, much like a debugger. Static verification or static code analysis, by contrast, involves detecting errors in the source code without ever compiling or running it, just by discovering logical inconsistencies. The type checking by a C compiler is an example of static verification. When a program is linked with PurifyPlus, corrected verification code is automatically inserted into the executable by parsing and adding to the object code, including libraries.

Pure, successor to the equational language Q, is a dynamically typed, functional programming language based on term rewriting. It has facilities for user-defined operator syntax, macros, arbitrary-precision arithmetic (multiple-precision numbers), and compiling to native code through the LLVM. Pure is free and open-source software distributed (mostly) under the GNU Lesser General Public License version 3 or later. Pure comes with an interpreter and debugger, provides automatic memory management, has powerful functional and symbolic programming abilities, and interfaces to libraries in C (e.g.

Image taken at the first Amiga show in Cologne (1989, Köln). Front row from left to right, and Fred Fish (November 4, 1952 - April 20, 2007) was a computer programmer notable for work on the GNU Debugger and his series of Fish disks of freeware for the Amiga. He was a pioneering spirit pervasive in the Amiga community. The Fish Disks (term coined by Perry Kivolowitz at a Jersey Amiga User Group meeting) became the first national rallying point, a sort of early postal system.

The Intellecs have resident monitors stored in ROMs. They also included an assembler, linker, and debugger, as well as the ability to act as an in-circuit emulator. Additionally, a PL/M compiler, cross-assembler and simulator were available, which allowed writing programs in a higher-level language than assembly. FORTRAN compilers were also available. The Intellec 8 supported a Teletype operating at 110 baud, a high speed punched paper tape readerIntel Microcomputer Peripherals: imm8-90 Intellec 8 High Speed Paper Tape Reader Google Docs.

The GNU compiler is currently declined in three versions: (MSPGCC) (MSPGCC Uniarch) TI consulted with RedHat to provide official support for the MSP430 architecture to the GNU Compiler Collection C/C++ compiler. This msp430-elf-gcc compiler is supported by TI's Code Composer Studio version 6.0 and higher. There is a very early llvm-msp430 project, which may eventually provide better support for MSP430 in LLVM. Other commercial development tool sets, which include editor, compiler, linker, assembler, debugger and in some cases code wizards, are available.

Shellcode cannot be executed directly. In order to analyze what a shellcode attempts to do it must be loaded into another process. One common analysis technique is to write a small C program which holds the shellcode as a byte buffer, and then use a function pointer or use inline assembler to transfer execution to it. Another technique is to use an online tool, such as shellcode_2_exe, to embed the shellcode into a pre-made executable husk which can then be analyzed in a standard debugger.

Working with Henry Baker, Parker had previously developed Micro-SPL, a systems programming language for the Xerox Alto. Action! was largely a port of Micro-SPL concepts to the Atari with the necessary changes to more directly handle the underlying MOS 6502 processor and add an editor and debugger. Action! was used to develop at least two commercial products—the HomePak productivity suite and Games Computers Play client program—and numerous programs in ANALOG Computing and Antic magazines. The editor portion was also used as the basis for the PaperClip word processor.

This architecture was unique because it allowed the developer to single-step even operating system code with semaphore locks, stored on an inferior disk volume. However, as the memory and source code of the D-series Xerox processors grew, the time to checkpoint and restore the operating system (known as a "world swap") grew very high. It could take 60-120 seconds to run just one line of code in the inferior operating system environment. Eventually, a co-resident debugger was developed to take the place of Co-Pilot.

Another mode is the so-called Daemon mode for distributed test execution. A specific integration with many test management tools like HP Quality Center / HP ALM, QMetry, TestLink, SQS-TEST/Professional Suite, Rational Quality Manager, Scapa TPP and Imbus TestBench is available, also some integrated pragmatic small-scale test management (including various reports). There is a test debugger (enabling arbitrary stepping and editing variables at run time) and a fully automated dependency management that takes care of pre- and postconditions and helps isolating test cases. Data-driven testing without the need for scripting is possible.

It was first released by the developers at the Massachusetts Institute of Technology (MIT), in 1986, as free software even before the Free Software Foundation, GNU, and the GPL existed. It is now part of the GNU Project.} It features a rich runtime software library, a powerful source code level debugger, a native code compiler and a built-in Emacs-like editor named Edwin. The books Structure and Interpretation of Computer Programs and Structure and Interpretation of Classical Mechanics include software that can be run on MIT/GNU Scheme.

Turbo Assembler (TASM) is a computer assembler (software for program development) developed by Borland which runs on and produces code for 16- or 32-bit x86 DOS or Microsoft Windows. It can be used with Borland's high-level language compilers, such as Turbo Pascal, Turbo Basic, Turbo C and Turbo C++. The Turbo Assembler package is bundled with the Turbo Linker, and is interoperable with the Turbo Debugger. TASM can assemble Microsoft Macro Assembler (MASM) source using its MASM mode and has an ideal mode with a few enhancements.

Microsoft needed a debugging program that could run in protected mode, so it hired Murray Sargent, a physics professor from the University of Arizona whose own debugging program could emulate applications in protected mode. Windows 3.0 originated in 1988 as an independent project by Weise and Sargent, who used the latter's debugger to find problems with Windows. They cobbled together a rough prototype that contained three applications: Microsoft Word, Microsoft Excel, and PowerPoint. They then presented it to company executives, who were impressed enough to approve it as an official project.

GeoWorks attempted to get third-party developers but was unable to get much support due to expense of the developer kit — which ran $1,000 just for the manuals — and the difficult programming environment, which required a second PC networked via serial port in order to run the debugger. Even though PC/GEOS is referred to as an "operating system", it still requires DOS in order to load. GEOS and its applications were written in a mix of 8086 assembly (Espire) and C (GOC), both with non-standard language extensions to support the object-oriented design.

Cygnus Solutions, originally Cygnus Support, was founded in 1989 by John Gilmore, Michael Tiemann and David Henkel-Wallace to provide commercial support for free software. Its tagline was: Making free software affordable. For years, employees of Cygnus Solutions were the maintainers of several key GNU software products, including the GNU Debugger and GNU Binutils (which included the GNU Assembler and Linker). It was also a major contributor to the GCC project and drove the change in the project's management from having a single gatekeeper to having an independent committee.

GPU PerfStudio is AMD's performance and debugging tool for graphics applications. It was initially developed to support Direct3D and OpenGL on Microsoft Windows only and was ported to Linux during 2013 and is available for Linux since the end of Q1 2014. The suite of tools is considered useful when developing games for Steam Linux and especially useful when optimizing games for AMD GPUs. GPU PerfStudio has an integrated Frame Profiles, Frame Debugger and API Trace with CPU timing information. GPU PerfStudio supports Direct3D 10, Direct3D 10.1, Direct3D 11 and OpenGL 4.2.

Whitehead together with Miller, Crane and Kaplan co-founded Activision, the first third-party video game developer, in October 1979. There, with others, he created a VCS development system with an integrated debugger and minicomputer-hosted assembler. It was used for most of Activision's VCS titles. He also developed a "venetian blinds" animation technique: an algorithm that horizontally reused and vertically interlaced sprites several times while rendering each frame, to give the illusion that the system had more than the maximum number of sprites allowed by the hardware.

ProDG (pronounced “prodigy”) by SN Systems is a suite of development tools produced for PlayStation 3, PlayStation 2, PSP, Nintendo DS, GameCube, and Game Boy Advance. The phrase PRO-DG was originally registered as a UK trademark, but the hyphen was never used for a released version and the suite has subsequently been known as ProDG. The suite consisted of console hardware- specific assemblers, a C/C++ compiler, ELF/DLL linkers, and a source-level debugger. The build tools could be controlled either from the command line or integrated with Microsoft Visual Studio.

There is no doubt developing Visual Studio packages is the most powerful way to add functionality to Visual Studio. The clear evidence for this is the fact that the whole Visual Studio functionality is built from packages integrated into the shell. All the languages, editors, the debugger, the project system and many more components are packages. From the developer point of view it actually means that adding a new package to Visual Studio is just like adding core functionality to the Visual Studio IDE as if it were developed by Microsoft.

Xen, a virtual machine monitor, can run in HVM (hardware virtual machine) mode, using Intel VT-x or AMD-V hardware x86 virtualization extensions and ARM Cortex-A7 and Cortex-A15 virtualization extension. This means that instead of paravirtualized devices, a real set of virtual hardware is exposed to the domU to use real device drivers to talk to. QEMU includes several components: CPU emulators, emulated devices, generic devices, machine descriptions, user interface, and a debugger. The emulated devices and generic devices in QEMU make up its device models for I/O virtualization.

Adobe Flash Builder (previously known as Adobe Flex Builder) is an integrated development environment (IDE) built on the Eclipse platform that speeds development of rich Internet applications (RIAs) and cross-platform desktop applications, particularly for the Adobe AIR platform. Adobe Flash Builder 4 is available in two editions: Standard and Premium. Adobe Flash Builder offers built-in code editors for MXML and ActionScript and a WYSIWYG editor for modifying MXML applications. Adobe Flash Builder includes an interactive debugger, allowing developers to step through code execution while inspecting variables and watching expressions.

A trap usually results in a switch to kernel mode, wherein the operating system performs some action before returning control to the originating process. A trap in a kernel process is more serious than a trap in a user process, and in some systems is fatal. In some usages, the term trap refers specifically to an interrupt intended to initiate a context switch to a monitor program or debugger. Deriving from this original usage, trap is sometimes used for the mechanism of intercepting normal control flow in some domains.

Some debuggers have the ability to modify program state while it is running. It may also be possible to continue execution at a different location in the program to bypass a crash or logical error. The same functionality which makes a debugger useful for correcting bugs allows it to be used as a software cracking tool to evade copy protection, digital rights management, and other software protection features. It often also makes it useful as a general verification tool, fault coverage, and performance analyzer, especially if instruction path lengths are shown.

A 2005 study found that using TDD meant writing more tests and, in turn, programmers who wrote more tests tended to be more productive. Hypotheses relating to code quality and a more direct correlation between TDD and productivity were inconclusive. Programmers using pure TDD on new ("greenfield") projects reported they only rarely felt the need to invoke a debugger. Used in conjunction with a version control system, when tests fail unexpectedly, reverting the code to the last version that passed all tests may often be more productive than debugging.

Major additions included reflection, a collections framework, Java IDL (an interface description language implementation for CORBA interoperability), and the integration of the Swing graphical API into the core classes. A Java Plug-in was released, and Sun's JVM was equipped with a JIT compiler for the first time. J2SE 1.3 (May 8, 2000) – Codename Kestrel. Notable changes included the bundling of the HotSpot JVM (the HotSpot JVM was first released in April, 1999 for the J2SE 1.2 JVM), JavaSound, Java Naming and Directory Interface (JNDI) and Java Platform Debugger Architecture (JPDA).

The script editor, SED, is a plain text editor with a compiler and debugger. However, key words like "function", "alpha", variable types, or numbers are highlighted in different colors for ease of identification, line numbers help to find syntax errors given by the engine faster, a code jumper allows jumping to different functions, actions and objects, and other functions further assist in programming and organizing projects. The script editor is used to program in Lite-c or C-Script (a scripting language somewhat similar to C used in previous generations but supported for compatibility's sake).

Software exception handling developed in Lisp in the 1960s and 1970s. This originated in LISP 1.5 (1962), where exceptions were caught by the `ERRSET` keyword, which returned `NIL` in case of an error, instead of terminating the program or entering the debugger. Error raising was introduced in MacLisp in the late 1960s via the `ERR` keyword. This was rapidly used not only for error raising, but for non- local control flow, and thus was augmented by two new keywords, `CATCH` and `THROW` (MacLisp June 1972), reserving `ERRSET` and `ERR` for error handling.

Microsoft does not routinely make available an IDE (Integrated Development Environment) for VBScript, although the Microsoft Script Editor has been bundled with certain versions of Microsoft Office. For debugging purposes the Microsoft Script Debugger can still be used in current Windows versions, even though the tool has not been updated in years. It allows the user to set break points in the VBScript code but the user interface is more than clumsy. There are VBScript debuggers available from third-party sources, and many text editors offer syntax highlighting for the language.

The Jade Software Corporation logo JADE is a proprietary object-oriented software development and deployment platform product from the New Zealand- based Jade Software Corporation, first released in 1996. It consists of the JADE programming language, Integrated development environment and debugger, integrated application server and object database management system. Designed as an end-to-end development environment to allow systems to be coded in one language from the database server down to the clients, it also provides APIs for other languages, including .NET Framework, Java, C/C++ and Web services.

Symbolic debuggers have existed since the mainframe era, almost since the first introduction of suitable computer displays on which to display the symbolic debugging information (and even earlier with symbolic dumps on paper). They were not restricted to high level compiled languages and were available also for Assembly language programs. For the IBM/360, these produced object code (on request) that included "SYM cards". These were usually ignored by the program loader but were useful to a symbolic debugger as they were kept on the same program library as the executable logic code.

Delphi is a software product that uses the Object Pascal programming language and provides an integrated development environment (IDE) for rapid application development of desktop, mobile, web, and console software, currently developed and maintained by Embarcadero Technologies. Delphi's compilers generate native code for Microsoft Windows, macOS, iOS, Android and Linux (x64). Delphi includes a code editor, a visual designer, an integrated debugger, a source code control component, and support for third-party plugins. The code editor features Code Insight (code completion), Error Insight (real-time error- checking), and refactoring.

It also has a gdt command (game debugging technique, a reference to the DDT debugger) which enables the player to move any object (including the player) to any room. Use of gdt requires answering a random question requiring deep knowledge of the game. The game's response to a wrong answer ("A booming voice says 'Wrong, cretin!' and you notice that you have turned into a pile of dust") appears in many "fortune cookie" databases. The Fortran version was also included in the distribution media for some Data General operating systems.

Daisy chained parallel port copy protection dongles. Efforts to introduce dongle copy-protection in the mainstream software market have met stiff resistance from users. Such copy-protection is more typically used with very expensive packages and vertical market software such as CAD/CAM software, cellphone flasher/JTAG debugger software, MICROS Systems hospitality and special retail software, Digital Audio Workstation applications, and some translation memory packages. In cases such as prepress and printing software, the dongle is encoded with a specific, per-user license key, which enables particular features in the target application.

Radio Shack offered simple graphics animation programs Micro Movie and Micro Marquee, and Micro Music. Radio Shack offered a number of programming utilities, including an advanced debugger, a subroutine package, and a cross reference builder. Probably the most popular utility package was Super Utility written by Kim Watt of Breeze Computing. Other utility software such as Stewart Software's Toolkit offered the first sorted directory, decoding or reset of passwords, and the ability to eliminate parts of TRSDOS that were not needed in order to free up floppy disk space.

SPI's RapiDev Tools Suite leverages the predictability of stream processing to provide a fast path to optimized results using C programming. Starting with C reference code, the Fast Functional Debugger (FFD) library plugs into standard tools, such as Microsoft Visual Studio and GNU, and simulates the DPU to support re- structuring code to kernels and streams. Because kernels are statically scheduled and data movement is explicit, DPU cycle-accuracy can be obtained even at this functional high level. This is one source of the predictability of the architecture.

When debugging the problem in a GUI, the programmer can try to skip some user interaction from the original problem description and check if remaining actions are sufficient for bugs to appear. After the test case is sufficiently simplified, a programmer can use a debugger tool to examine program states (values of variables, plus the call stack) and track down the origin of the . Alternatively, tracing can be used. In simple cases, tracing is just a few print statements, which output the values of variables at certain points of program execution.

OCaml ( , formerly Objective Caml) is a general-purpose, multi-paradigm programming language which extends the Caml dialect of ML with object-oriented features. OCaml was created in 1996 by Xavier Leroy, Jérôme Vouillon, Damien Doligez, Didier Rémy, Ascánder Suárez, and others. The OCaml toolchain includes an interactive top-level interpreter, a bytecode compiler, an optimizing native code compiler, a reversible debugger, and a package manager (OPAM). OCaml was initially developed in the context of automated theorem proving, and has an outsize presence in static analysis and formal methods software.

An integrated environment is the integration of the command-line interface with editors (typically multiple documents), help system and possibly debugging and other tools. Take Command Console (TCC) comes with an integrated environment with command line pane, file explorer, editor, batch debugger and more. PowerShell ISE includes a command line pane with support for integrated command line, copy-paste, multiple document editors, source-level debugging, help pane, command explorer pane and scripting interface allowing scripts/modules to manipulate menus, add-ons etc. The ISE (menus, windows, shortcuts, addons) are customizable through scripts.

In computing, CLISP is an implementation of the programming language Common Lisp originally developed by Bruno Haible and Michael Stoll for the Atari ST. Today it supports the Unix and Microsoft Windows operating systems. CLISP includes an interpreter, a bytecode compiler, debugger, socket interface, high-level foreign language interface, strong internationalization support, and two object systems: Common Lisp Object System (CLOS) and metaobject protocol (MOP). It is written in C and Common Lisp. It is now part of the GNU Project and is free software, available under the terms of the GNU General Public License (GPL).

The Atari 8-bit computer port of Donkey Kong contains one of the longest-undiscovered Easter eggs in a video game. Programmer Landon Dyer had his initials appear if the player died under certain conditions, then returned to the title screen. This remained undiscovered for 26 years until Dyer revealed it on his blog, stating "there's an easter egg, but it's totally not worth it, and I don't remember how to bring it up anyway." The steps required to trigger it were later discovered by Don Hodges, who used an emulator and a debugger to trace through the game's code.

When Alpha Micro released their MC68000 based microcomputer, Absoft expanded their offerings to Motorola and the Macintosh. The availability of MD68000-based machines made 32-bit Unix viable on small machines, and Absoft offered Fortran compilers for Unix machines by Data General, HP, Sun Microsystems, Tektronix, and others. In 1985 Microsoft licensed MacFortran, which consisted of a native ANSI FORTRAN 77 compiler and graphical debugger. Shortly thereafter, Microsoft contracted with Absoft to develop Microsoft Fortran for Macintosh, and a Microsoft BASIC compiler that was 100% syntax compatible with the existing Microsoft BASIC interpreter on the Macintosh.

This debugger supports not only the command line version but also the web server implementation allowing full interactive debugging of CGI applications in BASIC. The architecture of the interpreter internally is object oriented and provides a clean and well documented interface to embed the interpreter into any application written in C or C++. The whole source code is extensively documented and commented, which is an outstanding feature compared to other embeddable script language implementations. Slides in HTML format with English narration in RealAudio format are also available to get a jump start learning the architecture and module, preprocessor and embedding developments.

The ARM architectures used in smartphones, PDAs and other mobile devices range from ARMv5 to ARMv7-A, used in low-end and midrange devices, to ARMv8-A used in current high-end devices. In 2009, some manufacturers introduced netbooks based on ARM architecture CPUs, in direct competition with netbooks based on Intel Atom. Arm Holdings offers a variety of licensing terms, varying in cost and deliverables. Arm Holdings provides to all licensees an integratable hardware description of the ARM core as well as complete software development toolset (compiler, debugger, software development kit) and the right to sell manufactured silicon containing the ARM CPU.

As an addition to HPHPc, Facebook engineers also created a "developer mode" of HipHop (interpreted version of a PHP execution engine, known as HPHPi) and the HipHop debugger (known as HPHPd). These additions allow developers to run PHP code through the same logic provided by HPHPc while making it possible to interactively debug PHP code by defining watches, breakpoints, etc. Running the code through HPHPi yields lower performance when compared to HPHPc, but the developer benefits were, at the time, worth having to maintain these two execution engines for production and development. HPHPi and HPHPd were also open sourced in 2010.

The system's basic components include the GNU Compiler Collection (GCC), the GNU C library (glibc), and GNU Core Utilities (coreutils), but also the GNU Debugger (GDB), GNU Binary Utilities (binutils), the GNU Bash shell. GNU developers have contributed to Linux ports of GNU applications and utilities, which are now also widely used on other operating systems such as BSD variants, Solaris and macOS. Many GNU programs have been ported to other operating systems, including proprietary platforms such as Microsoft Windows and macOS. GNU programs have been shown to be more reliable than their proprietary Unix counterparts.

After graduating from Tokyo Zokei University, Ito joined Square in 1987. He initially worked on Final Fantasy and Final Fantasy II as a debugger but first became genuinely involved with game development while creating sound effects for Final Fantasy III. His next major role was as the designer of the Active Time Battle system for Final Fantasy IV. Square filed a Japanese patent application related to the ATB system on 16 July 1991 and a corresponding US application on 16 March 1992. One Japanese patent (JP2794230) and two US patents (US5390937 and US5649862) were granted based on these applications.

The assembler was very advanced, with a Lisp-like pattern- matching macro facility unmatched by almost any other assembler before or since. There was an always-resident debugger. Most of the system programs were written in PL/M, an ALGOL-like language from Intel which compiled directly to object code without a runtime library. The word processor was one of the first screen-oriented editors with many high-powered features, such as multiple views of the same file, cut/copy/paste, unlimited undo/redo, no typing lost after a crash or power failure, user-selectable fonts, and much more.

A programming tool or software development tool is a computer program that software developers use to create, debug, maintain, or otherwise support other programs and applications. The term usually refers to relatively simple programs, that can be combined together to accomplish a task, much as one might use multiple hand tools to fix a physical object. The most basic tools are a source code editor and a compiler or interpreter, which are used ubiquitously and continuously. Other tools are used more or less depending on the language, development methodology, and individual engineer,often used for a discrete task, like a debugger or profiler.

Original software titles were games, programming languages (BASIC, Pascal, a monitor/debugger, Assembler), text and graphics editors, etc. Due to the versatility and wide hardware capabilities Vector can be used for education, work and entertainment. As a gaming system it surpassed most of the other Soviet PC thanks to its unique multi-color palette and reasonably fast graphics, smooth hardware vertical scrolling, capabilities of the hardware overlay up to 4 image plans, 3-voices sound chip, a fairly large amount of RAM. It was created hundreds of games in assembler and thousands in Basic for Vector.

However, it has remained AutoCAD's main user customizing language. Vital-LISP, a considerably enhanced version of AutoLISP including an integrated development environment (IDE), debugger, compiler, and ActiveX support, was developed and sold by third party developer Basis Software. Vital LISP was a superset of the existing AutoLISP language that added VBA-like access to the AutoCAD object model, reactors (event handling for AutoCAD objects), general ActiveX support, and some other general Lisp functions. Autodesk purchased this, renamed it Visual LISP, and briefly sold it as an add-on to AutoCAD release 14 released in May 1997.

Borland Power Pack for DOS: Used to create 16- and 32-bit protected mode DOS applications, which can access a limited scope of the Windows API and call functions in any Windows DLL. Borland Code Guard: Once installed and integrated within the IDE, Code Guard can insert instrumentation code in the final executable that can be used to monitor: pointer usage, API calls, how many times some function is called, and other features. If some error is found, a pop-up window appears, the debugger can stop, or a log is written to disk. Delivered for 16- and 32-bit applications.

Gebelli was also responsible for creating what is considered to be the first RPG minigame, a sliding puzzle, which he added into the game despite it not being part of the original game design. Among the other developers were graphic designer Kazuko Shibuya, programmers Kiyoshi Yoshii and Ken Narita, as well as debugger Hiroyuki Ito. When the project started to show promise, designer Hiromichi Tanaka and his "B-Team" joined to aid development. The lack of faith in Sakaguchi's team, as well as its unpopularity within the company, motivated the staff members to give their best.

One can set code breakpoints, both for code in RAM (often using a special machine instruction) and in ROM/flash. Data breakpoints are often available, as is bulk data download to RAM. Most designs have "halt mode debugging", but some allow debuggers to access registers and data buses without needing to halt the core being debugged. Some toolchains can use ARM Embedded Trace Macrocell (ETM) modules, or equivalent implementations in other architectures to trigger debugger (or tracing) activity on complex hardware events, like a logic analyzer programmed to ignore the first seven accesses to a register from one particular subroutine.

After the debugger performs those operations, the state may be restored and execution continued using the RESTART instruction. Debug mode is also entered asynchronously by the debug module triggering a watchpoint or breakpoint, or by issuing a BKPT (breakpoint) instruction from the software being debugged. When it is not being used for instruction tracing, the ETM can also trigger entry to debug mode; it supports complex triggers sensitive to state and history, as well as the simple address comparisons exposed by the debug module. Asynchronous transitions to debug mode are detected by polling the DSCR register.

Komodo plug-ins are based on Mozilla Add-ons and extensions can be searched for, downloaded, configured, installed and updated from within the application. Available extensions include a Document Object Model (DOM) inspector, pipe features, additional language support and user interface enhancements. Komodo IDE has features such as integrated debugger support, DOM viewer, interactive shells, source code control integration, and the ability to select the engine used to run regular expressions, to ensure compatibility with the final deployment target. The commercial version also adds code browsing, a database explorer, collaboration, support for many popular source code control systems, and more.

A debug symbol is a special kind of symbol that attaches additional information to the symbol table of an object file, such as a shared library or an executable. This information allows a symbolic debugger to gain access to information from the source code of the binary, such as the names of identifiers, including variables and routines. The symbolic information may be compiled together with the module's binary file, or distributed in a separate file, or simply discarded during the compilation and/or linking. This information can be helpful while trying to investigate and fix a crashing application or any other fault.

It includes a new compiler run-time type information (RTTI) system, support for Windows 7 Direct2D, touch screen and gestures, a source code formatter, debugger visualizers and the option to also have the old style component palette in the IDE. The new RTTI system makes larger executables than previous versions. Delphi Prism 2010 (Version 3.0) which is the last Visual Studio 2008 only based one was also released in August 2009. ;Embarcadero Delphi XE Delphi XE (aka Delphi 2011, code named Fulcrum), was released on August 30, 2010 with Delphi support for Amazon EC2, Microsoft Azure were bundled.

Texas Instruments provides various hardware experimenter boards that support large (approximately two centimeters square) and small (approximately one millimeter square) MSP430 chips. TI also provides software development tools, both directly, and in conjunction with partners (see the full list of compilers, assemblers, and IDEs). One such toolchain is the IAR C/C++ compiler and Integrated development environment, or IDE. A Kickstart edition can be downloaded for free from TI or IAR; it is limited to 8 KB of C/C++ code in the compiler and debugger (assembly language programs of any size can be developed and debugged with this free toolchain).

Due to this, GLBasic can easily access third-party dynamic libraries on all platforms. The GLBasic SDK comes with an IDE, debugger, and a graphics engine built on OpenGL (or OpenGL ES) for the platforms Windows, Linux, Mac OS X, iOS, and WebOS. For handheld devices (Windows Mobile, GP2X, and GP2X Wiz), GLBasic uses its own close-to-hardware routines for fast graphics. To compile for the iPhone or iPad, you will need an i Mac (on which to compile the generated code - to comply with Apple's requirements) and the latest version of Xcode, which is a free download from the Apple website.

It also minimizes changes in the CPU, and adapts to many types of CPU. This was said to be especially apt for RISC-V because it is designed explicitly for many types of computers. The data-passing register allows a debugger to write a data-movement loop to RAM, and then execute the loop to move data into or out of the computer at a speed near the maximum speed of the debug system's data channel. Correspondents say that similar systems are used by MIPS Technologies MIPS, Intel Quark, Tensilica's Xtensa, and for Freescale Power ISA CPUs' background debug mode interface (BDM).

Although development of the emulator is still a work-in-progress, since 2004 it has been stable enough to let various unmodified guest operating systems run as if they were running on real hardware. Currently emulated processor architectures include ARM, MIPS, M88K, PowerPC, and SuperH. Guest operating systems that have been verified to work inside the emulator are NetBSD, OpenBSD, Linux, HelenOS, Ultrix, and Sprite. Apart from running entire guest operating systems, the emulator can also be used for experiments on a smaller scale, such as hobby operating system development, or it can be used as a general debugger.

The down side of this technique was that the firmware needed to be in a loop monitoring the level on the SID pin to receive data from the terminal. If the processor was doing some other task when the user pressed a key on the terminal, that data would be lost. In addition to having a reset button on the front of the computer, the Explorer 85 had an interrupt button. This allow the user to interrupt a locked up program and return to the debugger, without resetting the computer and losing all of their work.

The Oracle implementation is packaged into two different distributions: The Java Runtime Environment (JRE) which contains the parts of the Java SE platform required to run Java programs and is intended for end users, and the Java Development Kit (JDK), which is intended for software developers and includes development tools such as the Java compiler, Javadoc, Jar, and a debugger. Oracle has also released GraalVM, a high performance Java dynamic compiler and interpreter. OpenJDK is another notable Java SE implementation that is licensed under the GNU GPL. The implementation started when Sun began releasing the Java source code under the GPL.

CD-ROM of the LGX Yggdrasil Linux distribution release "Fall 1993" Yggdrasil announced their ‘bootable Linux/GNU/X-based UNIX(R) clone for PC compatibles’ on 24 November 1992 and made the first release on 8 December 1992. This alpha release contained the 0.98.1 version of the Linux kernel, the v11r5 version of the X Window System supporting up to 1024x768 with 256 colours, various GNU utilities such as their C/C++ compiler, the GNU debugger, bison, flex, and make, TeX, groff, Ghostscript, the elvis and Emacs editors, and various other software. Yggdrasil's alpha release required a 386 computer with 8 MB RAM and 100 MB hard disk.

Mingw-w64 is a free and open source software development environment to create Microsoft Windows applications. It was forked in 2005–2008 from MinGW (Minimalist GNU for Windows). Mingw-w64 includes a port of the GNU Compiler Collection (GCC), GNU Binutils for Windows (assembler, linker, archive manager), a set of freely distributable Windows specific header files and static import libraries which enable the use of the Windows API, a Windows native build of the GNU Project's GNU Debugger, and miscellaneous utilities. Mingw-w64 can be run either on the native Microsoft Windows platform, cross- hosted on Linux (or other Unix), or "cross-native" on MSYS2 or Cygwin.

The major features of the Apple Media Tool were a graphical authoring tool (AMT itself) and an associated programming environment - the Apple Media Tool Programming Environment (AMTPE) which was a compiler and debugger for the underlying Apple Media Language (AML - also known as the Key language). AMT was notable as one of the first authoring systems to support embedding Apple's pioneering QTVR movie format. AML is an object-oriented programming language based on Eiffel but specialized for multimedia programming. Although the AMT did not require any programming experience to use, it produced complete AML programs which were then compiled into byte code and interpreted by a runtime interpreter.

In its history, Stratus has offered hardware platforms based on the Motorola 68000 microprocessor family ("FT" and "XA" series), the Intel i860 microprocessor family ("XA/R" series), the HP PA-RISC processor family ("Continuum" series), and the Intel Xeon x86 processor family ("V Series"). All versions of VOS offer compilers targeted at the native instruction set, and some versions of VOS offer cross-compilers. Stratus added support for the POSIX API in VOS Release 14.3 (on Continuum), and added support for the GNU C/C++ compiler, GNU gdb debugger, and many POSIX commands in VOS Release 14.4. Each additional release of VOS has added more POSIX.

The Relax Kit and the Relax Lite Kit are low budget evaluation boards for the XMC4000 microcontroller family. The board contains the XMC4500 microcontroller (XMC4500-F100F1024 AA, Package: PG-LQFP-100), an ARM Cortex-M4F CPU running at 120 MHz, 1 MB Flash and 160 kB RAM. Besides that the Relax and Relax Lite Kit have a detachable on-board debugger so developers can download and validate the code without additional hardware. The Relax Kit and the Relax Lite Kit offer a complete set of on-board devices and plugs to run USB-based applications and to develop human machine interfaces with buttons and LEDs.

The first version of Embedded Wizard was released in 2003 by TARA Systems GmbH, an embedded software development company located in Munich, Germany. It was intended as a successor of previous GUI tools from TARA Systems GmbH, like M2-Builder. In contrast to former tools, Embedded Wizard enabled platform-independent development, introduced an own programming language Chora and was designed to support object oriented programming and resource-constrained devices (MCU). Since the first version, the tool has been extended with new features like an integrated debugger, a memory footprint analysis of RAM and flash consumption or support for effects and animations with a 3D perception and vector graphics.

Although BFD was originally designed to be a generic library usable by a wide variety of tools, the frequent need to tinker with the API to accommodate new systems' capabilities has tended to limit its use; BFD's main clients are the GNU Assembler (GAS), GNU Linker (GLD), and other GNU Binary Utilities ("binutils") tools, and the GNU Debugger (GDB). As a result, BFD is not distributed separately, but is always included with releases of binutils and GDB. Nevertheless, BFD is a critical component in the use of GNU tools for embedded systems development. The BFD library can be used to read the structured data out of a core dump.

Tools may be discrete programs, executed separately – often from the command line – or may be parts of a single large program, called an integrated development environment (IDE). In many cases, particularly for simpler use, simple ad hoc techniques are used instead of a tool, such as print debugging instead of using a debugger, manual timing (of overall program or section of code) instead of a profiler, or tracking bugs in a text file or spreadsheet instead of a bug tracking system. The distinction between tools and applications is murky. For example, developers use simple databases (such as a file containing a list of important values) all the time as tools.

Because of the high complexity of software, it is not possible to understand most programs at a single glance even for the most experienced software developer. The abstractions provided by high-level programming languages also make it harder to understand the connection between the source code written by a programmer and the actual program's behaviour. In order to find bugs in programs and to prevent creating new bugs when extending a program, a software developer uses some programming tools to visualize all kinds of information about programs. For example, a debugger allows a programmer to extract information about a running program in terms of the source language used to program it.

While on the one hand most simulators will be limited from being unable to simulate much other hardware in a system, they can exercise conditions that may otherwise be hard to reproduce at will in the physical implementation, and can be the quickest way to debug and analyze problems. Recent microcontrollers are often integrated with on-chip debug circuitry that when accessed by an in- circuit emulator (ICE) via JTAG, allow debugging of the firmware with a debugger. A real-time ICE may allow viewing and/or manipulating of internal states while running. A tracing ICE can record executed program and MCU states before/after a trigger point.

The department has five laboratories with a total area of about 2,400 Sq. Ft. The department has modernised Micro- Controller and Micro-Processor laboratories at a cost of Rs.15.5 lakhs with AICTE grants under MODROB scheme. The laboratories are equipped with Pentium IV Computer systems, PICSTART plus programmer (Target board 16F877 microchip), In-Circuit Debugger, PICKER-II Starter Kit, PIC Micro Controller Kit, PIC Micro Programmer, 8051 Micro Controller Kit, 16F877 Micro-Controller Chips, Micro Processor Kits, and Interface Modules. Modernized Digital Signal Processing laboratories, new Power Electronics, Data Acquisition and Control System laboratories have been set up. The Project Laboratory has excellent facilities for in-house student project works.

The $5,000 cost discouraged many from developing software for the ST. Later, the Atari Developer's Kit consisted of software and manuals (but no hardware) for $300. Included with the kit were a resource kit, C compiler (first Alcyon C, then Mark Williams C), debugger, and 68000 assembler (plus the non-disclosure agreement). The third-party Megamax C development package reduced the cost of entry to $200. Other development tools include 68000 assemblers (MadMac from Atari, HiSoft Systems's Devpac, TurboAss, GFA-Assembler), Pascal (OSS Personal Pascal, Maxon Pascal, PurePascal), Modula-2, C compilers (Lattice C, Megamax C, GNU C, Aztec C, AHCC), LISP, Prolog, and others.

Source-code editors have features specifically designed to simplify and speed up typing of source code, such as syntax highlighting, indentation, autocomplete and brace matching functionality. These editors also provide a convenient way to run a compiler, interpreter, debugger, or other program relevant for the software-development process. So, while many text editors like Notepad can be used to edit source code, if they don't enhance, automate or ease the editing of code, they are not source-code editors. Structure editors are a different form of source-code editor, where instead of editing raw text, one manipulates the code's structure, generally the abstract syntax tree.

A kernel debugger can usually break the storm by unloading the faulty driver, allowing the driver "underneath" the faulty one to clear the interrupt, if user input is still possible. As drivers are most often implemented by a 3rd party, most operating systems also have a polling mode that queries for pending interrupts at fixed intervals or in a round-robin fashion. This mode can be set globally, on a per-driver, per-interrupt basis, or dynamically if the OS detects a fault condition or excessive interrupt generation. A polling mode may be enabled dynamically when the number of interrupts or the resource use caused by an interrupt, passes certain thresholds.

June 8, 2001 Stylus Studio 3.0 was released. At the time it was primarily an XSLT IDE and the very first to feature an XSLT two-way editor and visual XML to XML mapping tool. June 2002 Stylus Studio 2004 released a two way visual schema designer for XML Schema 1.0 and the first IDE to feature postmortem stack trace for XSLT with back mapping to the XSLT source. At that time it was the only XSLT debugger supporting cross-debugging between XSLT and Java extension functions. September 2, 2003, Stylus Studio 5.0 introduced the very first XQuery two-way editor and visual XML to XML mapping tool.

On December 13, 2013, Valve released SteamOS, a gaming oriented OS based on Debian, for beta testing, and has plans to ship Steam Machines as a gaming and entertainment platform. Valve has also developed VOGL, an OpenGL debugger intended to aid video game development, as well as porting its Source game engine to desktop Linux. As a result of Valve's effort, several prominent games such as DotA 2, Team Fortress 2, Portal, Portal 2 and Left 4 Dead 2 are now natively available on desktop Linux. On July 31, 2013, Nvidia released Shield as an attempt to use Android as a specialized gaming platform.

They illustrated this by recounting one of Raskin's favorite demonstrations of FLOW, where he would close his eyes and hit random keys on the terminal, building a syntactically correct, albeit meaningless, program. Another aspect of the FLOW system's approach to user interaction was its debugger. This included the command , an analog to BASIC's that delayed after executing each statement in a fashion similar to modern single-step systems. On his return to University of California, San Diego (UCSD), Raskin was able to arrange funding from UCSD and matching funds from the National Science Foundation to purchase equipment to develop the FLOW system, a total of $76,000 ().

For native and managed code interoperability, Visual C++ introduces the STL/CLR, which is a port of the C++ Standard Template Library (STL) containers and algorithms to managed code. STL/CLR defines STL-like containers, iterators and algorithms that work on C++/CLI managed objects. Visual Studio 2008 features include an XAML-based designer (codenamed Cider), workflow designer, LINQ to SQL designer (for defining the type mappings and object encapsulation for SQL Server data), XSLT debugger, JavaScript Intellisense support, JavaScript Debugging support, support for UAC manifests, a concurrent build system, among others. It ships with an enhanced set of UI widgets, both for Windows Forms and WPF.

Internal anti-tampering is used to turn an application into its own security system and is generally done with specific code within the software that will detect tampering as it happens. This type of tamper proofing defense may take the form of runtime integrity checks such as cyclic redundancy checksums, anti-debugging measures, encryption or obfuscation. Execution inside a virtual machine has become a common anti- tamper method used in recent years for commercial software; it is used for example in StarForce and SecuROM. Some anti-tamper software uses white-box cryptography, so cryptographic keys are not revealed even when cryptographic computations are being observed in complete detail in a debugger.

Because this process happens very quickly, the blue screen may be seen only for an instant or not at all. Users have sometimes noted this as a random reboot rather than a traditional stop error, and are only aware of an issue after Windows reboots and displays a notification that it has recovered from a serious error. This happens only when the computer has a function called "Auto Restart" enabled, which can be disabled in the Control Panel which in turn shows the stop error. Microsoft Windows can also be configured to send live debugging information to a kernel debugger running on a separate computer.

It supports a long term compiling listener session which gives the compiler knowledge about the state of the compiled and thus running program, including the symbol table. This, in addition to dynamic linking, allows a function to be edited, recompiled, uploaded, and inserted into a running game without having to restart. The process is similar to the edit and continue feature offered by some C++ compilers, but allows programs to replace arbitrary amounts of code (even up to entire object files), and does not interrupt the running game with the debugger. This feature was used to implement code and to level streaming in the Jak and Daxter games.

Tagged pointers have some of the same difficulties as xor linked lists, although to a lesser extent. For example, not all debuggers will be able to properly follow tagged pointers; however, this is not an issue for a debugger that is designed with tagged pointers in mind. The use of zero to represent a null pointer does not suffer from these disadvantages: it is pervasive, most programming languages treat zero as a special null value, and it has thoroughly proven its robustness. An exception is the way that zero participates in overload resolution in C++, where zero is treated as an integer rather than a pointer; for this reason the special value nullptr is preferred over the integer zero.

One of the new features of GoLive version 5 was Dynamic Link, which was a method of creating dynamic, database-driven web content without the need to know a server-side language and with full WYSIWYG support in the GoLive user interface. GoLive had a powerful set of extensibility API which could be used to add additional functionality to the product. The GoLive SDK provided interfaces which allowed developers to use a combination of XML, JavaScript and C/C++ to create plugins for the product.Adobe GoLive SDK The extensibility API allowed developers access to custom drawing and event handling using JavaScript, as well as a full JavaScript debugger and command line interpreter.

Hard coding (also hard-coding or hardcoding) is the software development practice of embedding data directly into the source code of a program or other executable object, as opposed to obtaining the data from external sources or generating it at runtime. Hard-coded data typically can only be modified by editing the source code and recompiling the executable, although it can be changed in memory or on disk using a debugger or hex editor. Data that are hard-coded usually represent unchanging pieces of information, such as physical constants, version numbers and static text elements. Softcoded data, on the other hand, encode arbitrary information like user input, HTTP server responses, or configuration files, and are determined at runtime.

A core dump represents the complete contents of the dumped regions of the address space of the dumped process. Depending on the operating system, the dump may contain few or no data structures to aid interpretation of the memory regions. In these systems, successful interpretation requires that the program or user trying to interpret the dump understands the structure of the program's memory use. A debugger can use a symbol table, if one exists, to help the programmer interpret dumps, identifying variables symbolically and displaying source code; if the symbol table is not available, less interpretation of the dump is possible, but there might still be enough possible to determine the cause of the problem.

NET and Java Virtual Machine platforms, from the Gardens Point team around John Gough at Queensland University of Technology in Australia. On 23 June 2004 Oberon microsystems announced that the BlackBox Component Builder was made available as a free download and that an open-source version was planned. The beta open-source version was initially released in December 2004 and updated to a final v1.5 release in December 2005. It includes the complete source code of the IDE, compiler, debugger, source analyser, profiler and interfacing libraries and can also be downloaded from their website. Several release candidates for v1.6 appeared in the years 2009 – 2011, the latest one (1.6rc6) appeared on Oberon microsystems web pages in 2011.

The Go programming language is also supported, although with a limited set of application programming interfaces (API). The SDK includes a comprehensive set of development tools, including a debugger, software libraries, a handset emulator based on QEMU, documentation, sample code, and tutorials. Initially, Google's supported integrated development environment (IDE) was Eclipse using the Android Development Tools (ADT) plugin; in December 2014, Google released Android Studio, based on IntelliJ IDEA, as its primary IDE for Android application development. Other development tools are available, including a native development kit (NDK) for applications or extensions in C or C++, Google App Inventor, a visual environment for novice programmers, and various cross platform mobile web applications frameworks.

DPMS registering services can be disabled or re-enabled at any time after load using the or command, however, this will only affect new drivers loaded, not those already running and using DPMS. There are basically three revisions of the DPMS specification, DPMS beta, DPMS 1.0 (original Novell DOS 7 shipment) and DPMS 1.1 (since March 1994 update). The 1.0 specification continued to support the beta specification as well, whereas the 1.1 (and higher) implementation does not. DPMS saw its debut in beta versions of DR DOS "Panther" in October 1992, which, besides others, came with DPMS-enabled versions of the Super PC-Kwik disk cache, Addstor's SuperStor disk compression, and DEBUG as "stealth" protected mode system debugger.

During the development cycle, the programmer will typically run the program with assertions enabled. When an assertion failure occurs, the programmer is immediately notified of the problem. Many assertion implementations will also halt the program's execution: this is useful, since if the program continued to run after an assertion violation occurred, it might corrupt its state and make the cause of the problem more difficult to locate. Using the information provided by the assertion failure (such as the location of the failure and perhaps a stack trace, or even the full program state if the environment supports core dumps or if the program is running in a debugger), the programmer can usually fix the problem.

One basic way to debug software is to present a single threaded model, where the debugger periodically stops execution of the program and examines its state as exposed by register contents and memory (including peripheral controller registers). When interesting program events approach, a person may want to single step instructions (or lines of source code) to watch how a particular misbehavior happens. So for example a JTAG host might HALT the core, entering Debug Mode, and then read CPU registers using ITR and DCC. After saving processor state, it could write those registers with whatever values it needs, then execute arbitrary algorithms on the CPU, accessing memory and peripherals to help characterize the system state.

The graphics-text bimodality of OPM makes it suitable to jointly model requirements by a team that involves both the customer or his domain expert on one hand, and the system architect, modelers, and designers on the other hand. ; OPM model animated simulation OPM models are not just static graphical and textual representations of the system—they are also executable. A correct OPM model constructed in OPCAT can be simulated by animating it, visually expressing how the system behaves over time to achieve its function at all detail levels. An incorrect OPM model will not execute all the way through, and will indicate where and why it is stuck, effectively serving as a visual debugger.

Shriram Krishnamurthi is a computer scientist, currently a professor of computer science at Brown University and a member of the core development group for the Racket programming languages, responsible for creation of software packages including the Debugger, the FrTime package, and the networking library. Since 2006, Krishnamurthi has been a leading contributor to the Bootstrap curriculum, a project to integrate computer science education into grades 6–12. Krishnamurthi received his Ph.D. at Rice University in 2000, under the direction of Matthias Felleisen.. His dissertation is on linguistic reuse and macro systems in the presence of first-class modules. Starting from this topic, Krishnamurthi has moved into software engineering and is working on topics such as access control, modularization of verification, web-based interactive programming, and more.

Lattner's recent work involves designing, implementing, and evangelizing the LLVM and Clang compilers, productizing and driving the debugger LLDB, and overseeing development of the low-level toolchain. As of 2016, LLVM technologies are the core of Apple's developer tools and the default toolchain on FreeBSD. In June 2010, the Association for Computing Machinery (ACM) Special Interest Group on programming languages (SIGPLAN) gave Lattner its inaugural ACM SIGPLAN Programming Languages Software Award "for his design and development of the Low Level Virtual Machine", noting that Professor Adve has stated: "Lattner’s talent as a compiler architect, together with his programming skills, technical vision, and leadership ability were crucial to the success of LLVM." In April 2013, the ACM awarded Lattner its Software System Award,ACM (2013).

As the fifth employee of Sun Microsystems and founder of Cygnus Support, he became wealthy enough to retire early and pursue other interests. He is a frequent contributor to free software, and worked on several GNU projects, including maintaining the GNU Debugger in the early 1990s, initiating GNU Radio in 1998, starting Gnash media player in December 2005 to create a free software player for Flash movies, and writing the pdtar program which became GNU tar. Outside of the GNU project he founded the FreeS/WAN project, an implementation of IPsec, to promote the encryption of Internet traffic. He sponsored the EFF's Deep Crack DES cracker, sponsored the Micropolis city building game based on SimCity, and is a proponent of opportunistic encryption.

The device will be an open system and allow sideloading of games that are not part of a season, without the need for jailbreaking. Games are created using an SDK that includes a simulator and debugger and which is compatible with both the C and Lua programming languages. Currently the SDK is only available for macOS, although Panic have confirmed a version for Windows is in development. The screen technology used is Sharp's Memory LCD, which possesses some properties of e-paper displays. Each pixel can remember its state (black/white) without needing to be refreshed, resulting in faster refreshing and lower power usage, whilst also being “viewable in any light, from edge-of-vision darkness to brightest sunlight” and having a wide 170° viewing angle.

Next the application is run, showing the Cosmos Builder Window, which presents the developer with options which determine exactly how the project is compiled. These options include how to boot the project - via emulators such as Quick Emulator (QEMU), Virtual PC, and VMWare, writing to a disk image (ISO) file that can later be written to a CD-ROM, or via Preboot Execution Environment (PXE) network booting - as well as debug options using Cosmos' built-in debugger, and other options. When the user has chosen their desired options, they press the Build button. This invokes the IL2CPU compiler which systematically scans through all of the applications CIL code (excluding the Cosmos compiler code), converting it into assembly language for the selected processor architecture.

MPW provided a command line environment and tools, including 68k and PowerPC assemblers as well as Pascal, C and C++ compilers. The shell environment is somewhat similar to Unix shells in design, but is designed around the Macintosh's character set and GUI, replacing the usual terminal environment with a "worksheet" interface, allowing the user to select and run arbitrary sections of a shell script or to redo commands with no retyping. In addition, command line tools were commonly provided with a somewhat standardized graphical interface named Commando that provided limited access to the command line capabilities of the program. The debuggers were not integrated into MPW like most IDEs of today but the language compilers supported the symbolic debugging information file format used by the debugger.

In this setting, the PDP-1 quickly replaced the TX-0 as the favorite machine among the budding hacker culture, and served as the platform for a long list of computing innovations. This list includes one of the earliest digital video games, Spacewar!, the first text editor, the first word processor, the first interactive debugger, the first credible computer chess program, one of the very earliest time-sharing systems (BBN Time-Sharing System), and some of the earliest computerized music. At the Computer History Museum TX-0 alumni reunion in 1984, Gordon Bell said DEC's products developed directly from the TX-2, the successor to the TX-0 which had been developed at what Bell thought was a bargain price at the time, about .

When Psygnosis arranged an audience for SN Systems with Sony's Japanese executives at the January 1994 CES in Las Vegas, Beveridge and Day presented their prototype of the condensed development kit, which could run on an ordinary personal computer with two extension boards. Impressed, Sony decided to abandon their plans for a workstation-based development system in favour of SN Systems', thus securing a cheaper and more efficient method for designing software. An order of over 600 systems followed, and the company supplied Sony with additional software such as an assembler, linker, and a debugger. Sony strived to make game production as streamlined and inclusive as possible – an ethos which contrasted with the relatively isolated approach of rivals Sega and Nintendo.

Version 10 (Peregrine) debuted in a first beta version on June 3, 2009 and scored 100/100 on the Acid3 test, but failed the smoothness criteria. There was also a preview build that scored 100/100, released on March 28, 2009. Among other features, it also came with speed optimizations, inline spell checking for forms, an auto update feature, HTML mail formatting, web fonts and SVG font support, alpha transparency support using the RGBA and HSLA color models, and an updated version of the Opera Dragonfly web debugger. Opera Turbo, a mode which uses Opera's servers as proxy servers with data compression, reducing volume of data transferred by up to 80% (depending upon content), and thus increasing speed, was introduced.

The BXJ instruction attempts to switch to Jazelle state, and if allowed and successful, sets the "J" bit in the CPSR; otherwise, it "falls through" and acts as a standard BX (Branch) instruction. The only time when an operating system or debugger must be fully aware of the Jazelle mode is when decoding a faulted or trapped instruction. The Java program counter (PC) pointing to the next instructions must be placed in the Link Register (R14) before executing the BXJ branch request, as regardless of hardware or software processing, the system must know where to begin decoding. Because the current state is held in the CPSR, the bytecode instruction set is automatically reselected after task- switching and processing of the current Java bytecode is restarted.

When a Guru Meditation is displayed, the options are to reboot by pressing the left mouse button, or to invoke ROMWack by pressing the right mouse button. (ROMWack is a minimalist debugger built into the operating system which is accessible by connecting a 9600 bit/s terminal to the serial port.) A simulation of the Guru Meditation error message A Guru Meditation Error in the Nintendo DS homebrew software DSOrganize The alert itself appears as a black rectangular box located in the upper portion of the screen. Its border and text are red for a normal Guru Meditation, or green/yellow for a Recoverable Alert, another kind of Guru Meditation. The screen goes black, and the power and disk-activity LEDs may blink immediately before the alert appears.

The infected victim, upon encountering a "clean" A-gate, would then feel compelled to switch the gate into debugger mode, enter a set of commands, then upload him/herself, after which the gate would execute the infected boot-loader in his/her netlink, copy it into its working set, and thus become infected in turn. When a set amount of gates in a network became infected, they would begin communicating with each other and create privileged instruction channels which could be used by shadowy controllers with the correct authentication keys to control them remotely. They could defend themselves against attack, build and direct weapons to selected targets, and netlink to any number of T-gates. Eventually, the republic crumbled under the pressure, converting into a series of isolated, heavily firewalled polities.

There are also special-purpose tools called dump analyzers to analyze dumps. One popular tool, available on many operating systems, is the GNU binutils' objdump. On modern Unix-like operating systems, administrators and programmers can read core dump files using the GNU Binutils Binary File Descriptor library (BFD), and the GNU Debugger (gdb) and objdump that use this library. This library will supply the raw data for a given address in a memory region from a core dump; it does not know anything about variables or data structures in that memory region, so the application using the library to read the core dump will have to determine the addresses of variables and determine the layout of data structures itself, for example by using the symbol table for the program undergoing debugging.

Machine code monitor in a W65C816S single-board computer, displaying code disassembly, as well as processor register and memory dumps Apple II 6502 machine code monitor A machine code monitor ( machine language monitor) is software that allows a user to enter commands to view and change memory locations on a computer, with options to load and save memory contents from/to secondary storage. Some full-featured machine code monitors provide detailed control ("single-stepping") of the execution of machine language programs (much like a debugger), and include absolute-address code assembly and disassembly capabilities. Machine code monitors became popular during the home computer era of the 1970s and 1980s and were sometimes available as resident firmware in some computers (e.g., the built-in monitors in the Commodore 128, Heathkit H89 and Zenith laptops).

Double Fine created a number of internal tools and processes to help with the development of the game, as outlined by executive producer Caroline Esmurdoc. With the focus of the game on Raz as the playable character within a platformer game, the team created the "Raz Action Status Meeting" (RASM). These were held bi-weekly with each meeting focusing on one specific movement or action that Raz had, reviewing how the character controlled and the visual feedback from that so that the overall combination of moves felt appropriate. With extensive use of the Lua scripting language, they created their own internal Lua Debugger nicknamed Dougie, after a homeless man near their offices they had befriended, that helped to normalize their debugging processes and enable third-party tools to interact with the name.

3D GameStudio or 3DGS is a pan 3D computer game development system which allows the users to create 3D games and other virtual reality applications, and publish them royalty-free. It includes a model/terrain editor, a level editor, a script editor/debugger and comes with a big collection of textures, models and artwork, as well as a game template system that allows the creation of basic shooter games or RPGs without programming. For complex games or other applications, either the integrated programming language named Lite-C or an external development language such as Visual C++ or Borland Delphi can be used. Gamestudio is marketed at users of various skill levels, providing three different levels of usage ("beginner", "advanced", and "professional") for hobbyists, artists, as well as programmers.

The debugger program MacsBug was sometimes used even by end users to provide basic (though not always reliable) error recovery, and could be used for troubleshooting purposes, much as the output of a Unix kernel panic or a Windows NT Blue Screen of Death could be. Mac OS Classic bomb boxes were often ridiculed for providing little or no useful information about the error; this was a conscious decision by the Macintosh team to eliminate any information that the end user could not make sense of. The error code was intended to be included in a bug report to the developer. In Mac OS X, the system architecture is vastly different from that in the classic Mac OS, and an application crash can not usually bring down the entire system.

The code was originally written for OS/2 and had no user interface; a symbol was placed in the device driver where the packet buffers were kept so received data could be dumped in hex from within the kernel debugger. Netmon caused a bit of a stir for Microsoft IT since networks and e-mail were not encrypted at the time. Only a few software engineers had access to hardware analyzers due to their cost, but with Netmon many engineers around the company had access to network traffic for free. At the request of Microsoft IT, two simple identification features were added - a non- cryptographic password and an identification protocol named the Bloodhound- Oriented Network Entity (BONE) (created and named by Raymond Patch as a play on the codename Bloodhound).

Stelladaptor and 2600-daptor support allows real joysticks, paddles, and driving controllers to be used, and support is also included to access a real AtariVox device plugged into a serial port (and actually generate sound from the AtariVox device). Stella does not yet support the cassette-based titles designed to work with the Coleco KidVid cassette player but does have support for titles designed to work with the Starpath Supercharger and Spectravideo Compumate. Stella includes many facilities for homebrew developers, including an extensive built-in interactive debugger and disassembler supporting breakpoints, read/write traps, etc. Other major features include Blargg TV effects, a cheatcode system, support for user- defined palette files, state loading/saving (including a TimeMachine-like unwind/rewind capability), hardware-accelerated rendering and effects, event remapping, and an extensive built-in, cross-platform user interface (including a ROM launcher frontend).

PICkit 2 The PICkit 2 — introduced in May 2005PICkit 2 User's Guide, from which the product introduction date was inferred; also contains warning against using PICkit 2 programmer for production programming — replaced the PICkit 1. The most notable difference between the two is that the PICkit 2 has a separate programmer/debugger unit which plugs into the board carrying the chip to be programmed, whereas the PICkit 1 was a single unit. This makes it possible to use the programmer with a custom circuit board via an in-circuit serial programming (ICSP) header. This feature is not intended for so-called "production" programming, however. The PICkit 2 uses an internal PIC18F2550 with FullSpeed USB. The latest PICkit 2 firmware allows the user to program and debug most of the 8 and 16 bit PICmicro and dsPIC members of the Microchip product line.

If a programmer stops the program in a debugger, they can observe the contents of these 64 registers (and a few status registers) to determine the progress of the machine. One particular processor which implements this ISA, the Alpha 21264, has 80 integer and 72 floating-point physical registers. There are, on an Alpha 21264 chip, 80 physically separate locations which can store the results of integer operations, and 72 locations which can store the results of floating point operations (In fact, there are even more locations than that, but those extra locations are not germane to the register renaming operation.) The following text describes two styles of register renaming, which are distinguished by the circuit which holds the data ready for an execution unit. In all renaming schemes, the machine converts the architectural registers referenced in the instruction stream into tags.

His group developed Intel's ProShare video-conferencing technology, the Indeo video compression technology, and Intel's Display Control Interface and VxD graphics software, later licensed to Microsoft to form the core of DirectX. His research group worked with the MIT Media Lab, Xerox PARC, and other groups, and developed early prototypes of digital video recorders (DVRs), video broadcast servers, and other technologies.Fifth International World Wide Web Conference As manager of the i960 software development tools team from 1986–1996, McGeady was an early developer and promoter of open- source software, beginning with Richard Stallman's GNU C compiler and tools. McGeady wrote the i960 target for GNU Compiler Collection (gcc) and led the team that developed a suite of tools including a globally optimizing, trace- driven optimizer for gcc and the first GNU Debugger (gdb) port to a remote, stand-alone system.

The editor also features its own interpreted language, similar to C++, which allows for relatively simple mod programming, and a script editor and debugger, enabling the level designer to control gameplay events more directly. In addition to the standard level editor, there is also a mechanism editor for physics and collision setup, an animation editor for modifying camera paths and animation of objects, a skeleton editor for configuring the skeletal structures of characters, a destruction editor, mesh editor, model editor, and font editor. One of the most significant and more distinctive features of Serious Editor 2's level editor is that it allows for real-time editing. The level design process for most games often requires the level to be modified in the editor, compiled, saved, and then loaded separately in the game where it can be tested.

Some debuggers will automatically overwrite and destroy data that has been freed, usually with a specific pattern, such as `0xDEADBEEF` (Microsoft's Visual C/C++ debugger, for example, uses `0xCC`, `0xCD` or `0xDD` depending on what has been freedVisual C++ 6.0 memory-fill patterns). This usually prevents the data from being reused by making it useless and also very prominent (the pattern serves to show the programmer that the memory has already been freed). Tools such as Polyspace, TotalView, Valgrind, Mudflap,Mudflap Pointer Debugging AddressSanitizer, or tools based on LLVMDhurjati, D. and Adve, V. Efficiently Detecting All Dangling Pointer Uses in Production Servers can also be used to detect uses of dangling pointers. Other tools (SoftBound, Insure++, and CheckPointer) instrument the source code to collect and track legitimate values for pointers ("metadata") and check each pointer access against the metadata for validity.

In the early 1990s, Nomura was hired by Square and at first worked as a debugger for Final Fantasy IV. Some time later, the company's staff was divided and he was placed in the team in charge of Final Fantasy. After he had received some training by artist Tetsuya Takahashi, Nomura designed the monsters for Final Fantasy V. At that time, each Final Fantasy developer had their own plan book as a compilation of ideas to present to the director of a game. While the others typed their plan books at the computer and then printed them out, Nomura wrote his by hand and attached many drawings which impressed director Hironobu Sakaguchi and event planner Yoshinori Kitase. Nomura then became the graphic director of Final Fantasy VI. For this game, he conceived the characters Shadow and Setzer as well as their background stories.

Bochs (pronounced "box") is a portable IA-32 and x86-64 IBM PC compatible emulator and debugger mostly written in C++ and distributed as free software under the GNU Lesser General Public License. It supports emulation of the processor(s) (including protected mode), memory, disks, display, Ethernet, BIOS and common hardware peripherals of PCs. Many guest operating systems can be run using the emulator including DOS, several versions of Microsoft Windows, BSDs, Linux, Xenix and Rhapsody (precursor of Mac OS X). Bochs runs on many host operating systems, including Android, Linux, macOS, PlayStation 2, Windows, and Windows Mobile. Bochs is mostly used for operating system development (when an emulated operating system crashes, it does not crash the host operating system, so the emulated OS can be debugged) and to run other guest operating systems inside already running host operating systems.

ScummVM is a free and open source software project to make a portable, Simple DirectMedia Layer (SDL) library-based SCUMM-engine client which allows many of the SCUMM-engine games to be played on systems where the original versions will not work or have trouble operating, including modern Windows and Macintosh systems, Linux (including portable handhelds – Android, GP2X, GP2X Wiz, Maemo, etc.), BeOS-Haiku, AmigaOS (3.x, 4.0, and its clones MorphOS and AROS), Palm OS, Windows Mobile (Pocket PC), Dreamcast, PlayStation 2, PlayStation Portable, Nintendo DS, Wii, Symbian (SeriesXX and UIQ), iOS (iPad, iPhone, iPod Touch), webOS and QNX-Playbook platforms.SCUMMVM compatibility list scvm is a SCUMM interpreter developed by the ScummC author.DotSec Repository - scummc Read Me As of April 2008, it is in a prototype state, and is meant to become a script debugger for ScummC development.

The first release of the Clarion language was a DOS product named Clarion 1.0 and was first released in April 1986. Clarion was created by Bruce Barrington, one of the founders of healthcare firm "HBO & Company" (later acquired by McKesson Corporation,) and a small team of developers. Barrington's goal was to create a language that would be compact and expressive, and would maximize the use of the memory- mapped screen of the IBM PC by creating a screen designer. Version 1 produced pseudocode; the initial release included a screen designer, an interpreter, an editor, and a debugger. Initially it supported databases composed of DAT files which was Clarion’s proprietary ISAM file format. Bruce Barrington formed Barrington Systems and released version 1.0. Clarion 1.0 required use of a dongle, at a time when industry sentiment was turning against dongles. This was offset by the ability to create royalty-free applications.

Reporting bugs for the Linux kernel Author Michelle Delio suggests that it was on LKML that Tux, the official Linux mascot, was suggested and refinedThe Story Behind Tux the PenguinInitial thread for "Linux logo", although the accuracy of her reporting in other stories has been disputed. Many companies associated with Linux kernel make announcements and proposals on LKML; for example, Novell,Novell introduces Linux kernel debugger Intel,Intel, Red Hat cure open-source hiccup, Proposed ACPI Licensing change VMware, Linux team tells VMware and Xen to get their acts together, VMI i386 Linux virtualization interface proposal and IBM. IBM announces Journaled File System v 1.0.0 , Kernel Traffic #125 for 9 July 2001 The list subscribers include all the Linux kernel maintainers as well as other known figures in Linux circles, such as Jeff V. MerkeyLinus tells Merkey, "Cry me a river" and Eric S. Raymond.

In 1993, Helix Software Company's memory manager NETROOM 3 introduced a feature very similar to Novell's DPMS: CLOAKING was used to relocate Helix's and third-party drivers into extended memory and run them at ring 0. Providing its functions as an extension to the real-mode EMS and XMS interface, its protected mode services are available under INT 2Ch. A CLOAKING developer's kit was available which included a NuMega SoftICE debugger. Cloaked driver or TSR software hooking interrupts had to leave a small 11-byte stub in conventional memory which would invoke the CLOAKING server to pass execution to the protected mode portion of the driver software. CLOAKING includes support for seamless operation under Windows 3.x and Windows 95, providing compatible INT 2Ch services to protected mode drivers via a Windows VxD, as well as seamless debugging through Windows start-up using SoftICE.

MinGW ("Minimalist GNU for Windows"), formerly mingw32, is a free and open source software development environment to create Microsoft Windows applications. The development of the MinGW project has been forked with the creation in 2005–2008 of an alternative project called Mingw-w64. MinGW includes a port of the GNU Compiler Collection (GCC), GNU Binutils for Windows (assembler, linker, archive manager), a set of freely distributable Windows specific header files and static import libraries which enable the use of the Windows API, a Windows native build of the GNU Project's GNU Debugger, and miscellaneous utilities. MinGW does not rely on third-party C runtime dynamic- link library (DLL) files, and because the runtime libraries are not distributed using the GNU General Public License (GPL), it is not necessary to distribute the source code with the programs produced, unless a GPL library is used elsewhere in the program.

Communications between the controller and target take place using repeated calls of ptrace, passing a small fixed-size block of memory between the two (necessitating two context switches per call); this is acutely inefficient when accessing large amounts of the target's memory, as this can only be done in word sized blocks (with a ptrace call for each word). For this reason the 8th edition of Unix introduced procfs, which allows permitted processes direct access to the memory of another process - 4.4BSD followed, and the use of `/proc` for debugger support was inherited by Solaris, BSD, and AIX, and mostly copied by Linux. Some, such as Solaris, have removed ptrace as a system call altogether, retaining it as a library call that reinterprets calls to ptrace in terms of the platform's procfs. Such systems use ioctls on the file descriptor of the opened `/proc` file to issue commands to the controlled process.

As a result, HHVM has certain similarities to the virtual machines used by other programming languages, including the Common Language Runtime (CLR, for the C# language) and Java virtual machine (JVM, for the Java language). HHVM brings many benefits in comparison with HPHPc, and one of them is almost complete support for the entire PHP language as defined by the official implementation of PHP version 5.4, including the HHVM's support for `create_function()` and `eval()` constructs. Furthermore, HHVM uses the same execution engine when deployed in both production and development environments, while supporting integration between the execution engine and the HPHPd debugger in both environment types; as a result, maintaining HPHPi (HipHop interpreter) separately as a development utility is no longer needed as it was the case with HPHPc. HHVM also eliminates the lengthy builds required by HPHPc to run PHP programs, resulting in much simpler development and deployment processes than it was the case with HPHPc.

Oracle Warehouse Builder was built from the ground up in Oracle, it was first released in January 2000 (release 2.0.4). The 3i release significantly enhanced the ETL mapping designer, then 9i in 2003 introduced the mapping debugger, process flow editing, integrated match/merging and name/address cleansing, multi-table insert, scripting, RAC certification to name a few. The 10gR1 release was essentially a certification of the 10g database, and the 10gR2 release (code named Paris) was a huge release incorporating a wide spectrum of functionality from dimensional modelling to data profiling and quality. The OWB 11gR1 release was a move into the database release stack, and included the server components being installed with the database and MDM connectors. The packaging as part of the Oracle Developer Suite ended in May 2006 with the release of OWB 10gR2 (10g Release 2), when the core functions were included in Oracle 10gR2 Standard Edition and Enterprise Edition.

In software, a toolchain is a set of programming tools that is used to perform a complex software development task or to create a software product, which is typically another computer program or a set of related programs. In general, the tools forming a toolchain are executed consecutively so the output or resulting environment state of each tool becomes the input or starting environment for the next one, but the term is also used when referring to a set of related tools that are not necessarily executed consecutively. A simple software development toolchain may consist of a compiler and linker (which transform the source code into an executable program), libraries (which provide interfaces to the operating system), and a debugger (which is used to test and debug created programs). A complex software product such as a video game needs tools for preparing sound effects, music, textures, 3-dimensional models and animations, together with additional tools for combining these resources into the finished product.

The primary difference from GOTO is that GOTO only depends on the local structure of the code, while COMEFROM depends on the global structure – a GOTO transfers control when it reaches a line with a GOTO statement, while COMEFROM requires scanning the entire program or scope to see if any COMEFROM statements are in scope for the line, and then verifying if a condition is hit. The effect of this is primarily to make debugging (and understanding the control flow of the program) extremely difficult, since there is no indication near the line or label in question that control will mysteriously jump to another point of the program – one must study the entire program to see if any COMEFROM statements reference that line or label. Debugger hooks can be used to implement a COMEFROM statement, as in the humorous Python goto module; see below. This also can be implemented with the gcc feature "asm goto" as used by the Linux kernel configuration option CONFIG_JUMP_LABEL.

Q-Bus board with LSI-11/2 CPU DEC "Fonz-11" (F11) Chipset DEC "Jaws-11" (J11) Chipset The LSI-11 (PDP-11/03), introduced in February 1975 is the first PDP-11 model produced using large-scale integration; the entire CPU is contained on four LSI chips made by Western Digital (the MCP-1600 chip set; a fifth chip can be added to extend the instruction set, as pictured on the right). It uses a bus which is a close variant of the Unibus called the LSI Bus or Q-Bus; it differs from the Unibus primarily in that addresses and data are multiplexed onto a shared set of wires rather than having separate sets of wires. It also differs slightly in how it addresses I/O devices and it eventually allowed a 22-bit physical address (whereas the Unibus only allows an 18-bit physical address) and block-mode operations for significantly improved bandwidth (which the Unibus does not support). The CPU microcode includes a debugger: firmware with a direct serial interface (RS-232 or current loop) to a terminal.

Signatures inside the Macintosh 128K case The original Macintosh was unusual in that it included the signatures of the Macintosh Division as of early 1982 molded on the inside of the case. The names were Peggy Alexio, Colette Askeland, Bill Atkinson, Steve Balog, Bob Belleville, Mike Boich, Bill Bull, Matt Carter, Berry Cash, Debi Coleman, George Crow, Donn Denman, Christopher Espinosa, Bill Fernandez, Martin Haeberli, Andy Hertzfeld, Joanna Hoffman, Rod Holt, Bruce Horn, Hap Horn, Brian Howard, Steve Jobs, Larry Kenyon, Patti King, Daniel Kottke, Angeline Lo, Ivan Mach, Jerrold Manock, Mary Ellen McCammon, Vicki Milledge, Mike Murray, Ron Nicholson Jr., Terry Oyama, Benjamin Pang, Jef Raskin, Ed Riddle, Brian Robertson, Dave Roots, Patricia Sharp, Burrell Smith, Bryan Stearns, Lynn Takahashi, Guy "Bud" Tribble, Randy Wigginton, Linda Wilkin, Steve Wozniak, Pamela Wyman and Laszlo Zidek. The Macintosh 128/512K models also included Easter eggs in the OS ROM. If the user went to the system debugger and typed `G 4188A4`, a graphic reading "Stolen from Apple Computers" would appear in the upper left corner of the screen.

Each Emacs window has a status bar called the "mode line" displayed by default at the bottom edge of the window. Emacs windows are available both in text-terminal and graphical modes and allow more than one buffer, or several parts of a buffer, to be displayed at once. Common applications are to display a dired buffer along with the contents of files in the current directory (there are special modes to make the file buffer follow the file highlighted in dired), to display the source code of a program in one window while another displays a shell buffer with the results of compiling the program, to run a debugger along with a shell buffer running the program, to work on code while displaying a man page or other documentation (possibly loaded over the World Wide Web using one of Emacs' built-in web browsers) or simply to display multiple files for editing at once such as a header along with its implementation file for C-based languages. In addition, there is , a minor mode that chains windows to display non-overlapping portions of a buffer.

SYS file is limited to a few kilobytes under MS-DOS/PC DOS (up to 64 KB in most recent versions), whereas the file's size is unlimited under DR-DOS. This is because the former operating systems (since DOS 3.0) will compile the file into some tokenized in-memory representation before they sort and regroup the directives to be processed in a specific order (with device drivers always being loaded before TSRs), whereas DR-DOS interprets the file and executes most directives line-by-line, thereby giving full control over the load order of drivers and TSRs via `DEVICE` and `INSTALL` (for example to solve load order conflicts or to load a program debugger before a device driver to be debugged) and allowing to adapt the user interaction and change the flow through the file based on conditions like processor types installed, any type of keys pressed, load or input errors occurring, or return codes given by loaded software. This becomes particularly useful since `INSTALL` can also be used to run non-resident software under DR- DOS, so that temporary external programs can be integrated into the CONFIG.SYS control flow.
