who cares about optimization like this, teh performance diff for compiling
for specific architectures is between 5-10%.
For most cases "It does not matter."
Just recompile the kernel yourself.
Uou are correct in nereal, but there are a handful of packages where
speed change is *not* 5-10%, or is needed for other reasons. openssl
comes to mind, and XFree*-GLU* is gonna need afaict as well.
Howvere, arch is not at all the right representation for these speedups,
something like
Requires: cpuinfo(cmov)
is. I.e. inventing a lot of arch names to track functionailty implicitly
is just broken each and every time, say, and x86_64 is released.
Tracking the necessary functionality explicitly and narrowly is a far better
approach, particularly if a runtime probe, rather than static content, is
attempted.
