Quite a good article! Shame it doesn't apply to us. I can't remember where I read it, but the gcc crew were talking about doing an overhaul (or at least an investigation) into -O1 -O2 and -O3. As previous informal benchmarks done by Gentooists show, with the current GCC compilers (including 3.3) -O2 can often produce faster code than -O3. This is meant to have been addressed in 3.4. On the other hand, the code for his tester can be downloaded and then modified only cover gcc33/32 optimizations. Anybody know of a few noninteractive benchmark programs that could be tested with? I'm happy to run some tests and publish results for AthlonXP using gcc33. Jason -- [EMAIL PROTECTED] mailing list
