Does someone know where can i find some 
info about profiling with gcc (other than gcc and gprof manual ) 
?
I need info about how can i do my own profiling 
library.
Thanks Adi

You can certainly use the source code of gcc in addition to the
manual. If you find the source code answers a question that is not
answered in the manual but should, please contribute a patch to the
documentation.

You could start by telling us what source exactly you've found, and
where you found it.

gprof support is also part of gcc, by means of the 'gcc -pg'
option. So part of the gprof implementation is in gcc.

gcc source code is on gcc.gnu.org

Please have a look at the gprof manual, in particular (gprof)Details
(with subsections on implementation, the file format, internals and
debugging). For GCC, you'll find details in (gcc)Profiling. These are
all info files, which should come with your typical Linux
distribution.
