As long as amd64 and i386 switch too, then I think it would be okay for
us to do the same? But I really want to hear confirmation from Robert
My own reasons for wanting gcc-4.7 would be: keep consistency with
amd64/i386; stricter checking of code, which might catch something
important for us; hopefully less memory used by the linker. And I
think this would be the last chance to do this before the freeze.
The most sensitive thing on kFreeBSD would be the kernel. Upstream
still builds kfreebsd-8 with gcc-4.4. The Debian kfreebsd packages will
ignore the system's default GCC and use gcc-4.6, so a change of default
shouldn't be an issue.
I tried anyway with gcc-4.7, and src:kfreebsd-9 successfully built a
kfreebsd-i386 kernel that seems stable for a few days now. Also the
freebsd-utils (essential stuff for kfreebsd-* arches) were okay.
I guess upstream has spent a lot of time already fixing up code for
Clang/LLVM, which might reduce the impact of switching to gcc-4.7.
