Greeting, Could anybody give me some advise about the kernel profiling implementation in FreeBSD. Specifically, I am confused by: 1. Is the asm code in /sys/i386/isa/prof_machdep.c the entry code plugged into each function? and it calls _MCOUNT_DECL(frompc, selfpc) in /sys/libkern/mcount.c, which to my understanding is the implementation doing real profiling?
2. How does __mcount linked by each function? I know GCC has an option -finstrument-functions and one can write __cyg_profile_func_enter() and __cyg_profile_func_exit() procedure. But what mechanism is used for mcount? Thanks a lot - Yaoping R. To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
