Hi Everyone-
I can't get accurate results for functions called more than 2^32-1 times in
gprof; it looks like somewhere the function call counts are limited to 32-bit
integers, even though I am compiling on a 64-bit architecture. Does anyone know
if this is a limitation of gprof or of the gcc implementation of the -pg option?
Is there a workaround? I am using binutils 2.17 and gcc 4.1.2 on Debian. Thanks
very much.
