Subject: g++ 3.4 and -fprofile-generate

Author: Frank Phillips

Date: 10:09:14 02/16/05

Has anybody got any experience with g++ 3.4 for amd64 (x86_64) - for Linux?

I have been using the profile generated optimisation option, but the code it
produces is no faster then with simple -O3.

I simply compile with -fprofile-generate
then run,
then recompile with -fprofile-use.

The relevant *.gcno, *.gcda files are produced.  Must be doing something
wrong.....
