When you are done with the variable, you can unwatch it.from watchpoints import watch, unwatch a = 0 watch(a) a = 1 unwatch(a) a = 2 # nothing will happen Or you can unwatch everything by passing no argument to itunwatch() # unwatch everything print to different stream...
Set a breakpoint at line 45, or at myfunction. The program will pause when it reaches the breakpoint. watch x == 3 Set a watchpoint, which pauses the program when a condition changes (when x == 3 changes). Watchpoints are great for certain inputs (myPtr != NULL) without having t...

When the GPU hits a breakpoint or any other event that would normally cause the GPU to freeze, CUDA-GDB releases the GPU for use by the desktop or other applications. This enables CUDA-GDB to debug a CUDA application on the same GPU that is running the desktop GUI, and also enables ...
‣ Use the following command: set cuda software_preemption on ‣ Export the following environment variable: CUDA_DEBUGGER_SOFTWARE_PREEMPTION=1 Either of the options above will activate software preemption. These options must be set prior to running the application. When the GPU hits a break...
specified precedence rules are used to break ambiguities. You must compile the output file, y.tab.c, with a C language compiler to produce a yyparse function. This function must be loaded with the yylex lexical analyzer, as well as with the main subroutine and the yyerror error-handling subr...
Watchpoints:GDB can watch a variable and stop execution whenever it changes. This feature is useful when debugging programs where a variable is being modified unexpectedly. Backtracing:When a program crashes, GDB can show the function calls that led to the crash, known as a backtrace. This fea...
Program received signal SIGTRAP, Trace/breakpoint trap. 0x0000000004963fb4 in write () from /lib64/libc.so.6 But how is this possible? Valgrind points to line 45 of theexample.ccode, where the structure b2 is written to the file. When looking at the code, you can see that the structu...
