I guess we can keep -march for -m32 powerpc unchanged then, -mtune will be still power6. We can default to -march=power4 for -m32 for RHEL only (already RHEL5 has power4 built shared glibc libraries). > >For the -march/-mcpu default changes, I think nothing is required from the > >koji build infrastructure (I don't think there are 31-bit mainframes > >around in koji/brew and I don't think there are 32-bit powerpcs or > >i386/i486s among the build boxes either), on the other side that decision > >has to be made almost immediately (before the world is rebuilt with gcc > >4.4.0). > > I'm going to assmue that you are wanting a mass-rebuild of all of Fedora with > gcc 4.4.

Beta freeze is March 10. Yes, I want a mass rebuild with gcc 4.4 for Fedora 11, and new gcc can land into dist-f11 during this week. > >For glibc --enable-kernel= default this requires that all koji build boxes > >and anything else that needs to run Fedora 11 binaries runs at least 2.6.29 > >kernels, but the change might be still delayed for a few weeks. > > The koji build boxes all run RHEL 5. Getting them upgraded to a not-yet- > released kernel seems unlikely. I know it is a pain, on the other hand it would really improve Fedora 11.
