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
This led to the development of proprietary software from several independent vendors that provided similar features but deliberately restricted breakpoints and instruction stepping to particular application programs in particular address spaces and threads. The program state (as applicable to the chosen application/thread) was saved for ...
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 ...
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.
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.
The same mode is also used by KGDB for debugging a running Linux kernel on the source level with gdb. With KGDB, kernel developers can debug a kernel in much the same way as they debug application programs. It makes it possible to place breakpoints in kernel code, step through the code, and observe variables.
A breakpoint immediately after a Document.Write is ignored. Entering a Document.Write command while debugging, or refreshing a document in Internet Explorer while debugging it, can cause hangs or other unexpected behavior. Unlike in other debuggers, there is no Watch window for monitoring variables; they must be checked via manual commands.
On-chip debugging is an alternative to in-circuit emulation. It uses a different approach to address a similar goal. On-chip debugging, often loosely termed as Joint Test Action Group (JTAG), uses the provision of an additional debugging interface to the live hardware, in the production system. It provides the same features as in-circuit ...
