Function Documentation

◆ attribute()

__attribute__ ( (__no_instrument_function__, __no_profile_instrument_function__) )

Writes gmon.out dump file and stops profiling Called from atexit() handler; will dump out a gmon.out file at cwd with all collected information.

Internal timer handler.

Internal C handler for _mcount()

Parameters

frompc	pc address of caller
selfpc	pc address of current function

Called from mcount.S to make life a bit easier. __mcount is called right before a function starts. GCC generates a tiny stub at the very beginning of each compiled routine, which eventually brings the control to here.
