Re: gcc300 vs gcc295.3 benchmarking?




While 3.0 shouldn't give worse results than 2.95.3, note that stack
alignment only works as well as your libraries and startup modules are
aligned.  Most installed libc's aren't, and hence, no matter how well
3.0 maintains alignment, chances are your code isn't aligned.  

To fix this you have to rebuild libc with your preferred alignment
options (although not with -malign-double!), and AFAIK, 3.0 still
won't build glibc 2.2.3.  (Anybody have an update on this?)
