The debugging interface of Eclipse with a program suspended at a breakpoint. Panels with stack trace (upper left) and watched variables (upper right) can be seen. In software development, a breakpoint is an intentional stopping or pausing place in a program, put in place for debugging purposes. It is also sometimes simply referred to as a pause
A debug register may be either the source operand or destination operand. The debug registers are privileged resources; the MOV instructions that access them can only be executed at privilege level zero. An attempt to read or write the debug registers when executing at any other privilege level causes a general protection fault.
by setting a memory breakpoint on a condition of write and/or read to those bytes, or by pre-initializing the guard bytes with specific values and checking the values upon deallocation. The first way is possible only with a debugger that handles such breakpoints, but significantly increases the chance of locating the problem.
Induced interrupt This technique involves forcing a breakpoint at certain points in a program at execution time, usually by altering the machine code instruction at that point (this might be an inserted system call or deliberate invalid operation) and waiting for an interrupt. When the interrupt occurs, it is handled by the testing tool to ...
Time travel debugging or time traveling debugging is the process of stepping back in time through source code to understand what is happening during execution of a computer program. [1] Typically, debugging and debuggers , tools that assist a user with the process of debugging, allow users to pause the execution of running software and inspect ...
Winpdb debugging itself. A debugger is a computer program used to test and debug other programs (the "target" programs). Common features of debuggers include the ability to run or halt the target program using breakpoints, step through code line by line, and display or modify the contents of memory, CPU registers, and stack frames.
Breakpoints... Programs halt when a specified event, a breakpoint, has occurred. The event can be specified as a code execution address, or as a data access (read or write) to an address with a specified value. Nexus breakpoints can be set at any address, including flash or ROM memory; CPUs may also provide special breakpoint instructions.
Many video gaming mod, cheat codes, such as level cheat code, invincibility, etc. were originally introduced as debug code to allow the programmers and/or testers to skip hindrances that would prevent them from rapidly getting to parts of the game that needed to be tested; and in these cases cheat modes are often referred to as debugging mode.
