A special startup routine allocates memory for the histogram andeither calls profil() or sets up a clock signal handler. This routine(monstartup) can be invoked in several ways. On Linux systems, aspecial profiling startup file gcrt0.o, which invokes monstartup beforemain, is used instead...
Profiling works by changing how every function in your program iscompiled so that when it is called, it will stash away some informationabout where it was called from. From this, the profiler can figure outwhat function called it, and can count how many times it was called.This change is ...
