Hello !

I'm trying to add prof or gprof support to a port of gcc to OS/2.
I just detected that -p causes calls of a function _mcount at the beginning
of a function. How does _mcount know the name of the starting function ?
How does it remark the end of it ?

Where do I find the source of an _mcount function (if in assembler,
I would prefer 386 :-) ?

Because I did not subscribe to help-gcc, please reply to:
joerg_viola@ms.maus.de

Thanks in advance, joerg
