Description Sammy 2007-02-09 17:05:45 UTC
Is it possible to update gcc from 4.1 branch for FC6 as well to include
the core2 support. I have a couple of core2 extremes and would like to 
see how much difference these make.

Comment 1 Jakub Jelinek 2007-02-09 17:18:06 UTC
The intrinsics are already there and so is MNI support, and while core2 support
has been added only in rawhide (so you can't use -march=core2),
-march=nocona -mmni -mtune=generic is a good enough replacement for -march=core2
and -mtune=core2 is almost identical to -mtune=generic even on GCC trunk.
FYI, rawhide gcc groks both the -mmni and -mssse3 switches, FC6 only -mmni
and GCC trunk only -mssse3.

Whenever FC6 gcc is updated, it will get these changes (they are already
on redhat/gcc-4_1-branch; so there is no point in keeping this bug open), but
there is no firm plan for it, it might take a month or three.
