In computing, a stack trace (also called stack backtrace [1] or stack traceback [2]) is a report of the active stack frames at a certain point in time during the execution of a program. When a program is run, memory is often dynamically allocated in two places: the stack and the heap. Memory is continuously allocated on a stack but not on a ...
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. Thus assertions provide a very powerful tool in debugging.
A trace tree is a data structure that is used in the runtime compilation of programming code. Trace trees are used in tracing just-in-time compilation where tracing is used during code execution to look for hot spots before compilation. When those hot spots are entered again the compiled code is run instead.
Since the trace is recorded by following one concrete execution path of the loop, later executions of that trace can diverge from that path. To identify the places where that can happen, special guard instructions are inserted into the trace. One example for such a place are if statements.
Arm MAP, a performance profiler supporting Linux platforms.; AppDynamics, an application performance management solution [buzzword] for C/C++ applications via SDK.; AQtime Pro, a performance profiler and memory allocation debugger that can be integrated into Microsoft Visual Studio, and Embarcadero RAD Studio, or can run as a stand-alone application.
Free and open-source software portal; eBPF – Linux kernel tracing backend providing a set of features similar to DTrace [30] since kernel version 4.9; ftrace – a tracing framework for the Linux kernel, capable of tracing scheduling events, interrupts, memory-mapped I/O, CPU power state transitions, etc.
Depending on the architecture and operating system, the running program can not only handle the event but may extract some information about its state like getting a stack trace, processor register values, the line of the source code when it was triggered, memory address that was invalidly accessed [8] and whether the action was a read or a ...
[4] When passing a callback to a system that expects to call a C function, but one wants it to execute the method of a particular instance of a class written in C++, one uses a short trampoline to convert the C function-calling convention to the C++ method-calling convention. One way of writing such a trampoline is to use a thunk. [5]
