(please CC on replies, I'm not on rpm-maint@)
The attached patch adds a 'v' near the end of the machine name if
the (ARM) system we're running on supports VFP. This allows building
and using VFP-optimised RPM packages for ARM systems that have a VFP
floating point unit.
So e.g. glibc-2.7-2.armv5tel.rpm is the regular (softfloat) glibc that
we have now, and glibc-2.7-2.armv5tevl.rpm would then be a glibc built
to use VFP instructions, installable only on systems that have HWCAP_VFP.
The idea behind this is that we want to support multiple different
flavors of the Fedora/ARM port. Right now we have just an armv5tel
softfloat flavor, but we'll probably end up with a VFP flavor soon,
and later on perhaps also an ARMv6 flavor, maybe a pure Thumb2 flavor
at some point, etc.
(I would really like not to have to parse /proc/cpuinfo, but I don't
see how to get at _dl_hwcap or AT_HWCAP -- as far as I see, ld.so uses
this info to determine its library search path but doesn't export the
info.)
Ideas?
