What about ports/sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu?
There you have non FP versions of {get,set,swap}context. I need those for e300c2
Will these be used by glibc without this patch?
I don't quite get the Implies file is seems as I just noticed this too:
ports/sysdeps/unix/sysv/linux/powerpc/powerpc32/e300c2/nofpu configure: WARNING: ports/sysdeps/unix/sysv/linux/powerpc/powerpc32/e300c2/nofpu/Implies specifies nonexistent powerpc/powerpc32/nofpu
configure: WARNING: ports/sysdeps/unix/sysv/linux/powerpc/powerpc32/e300c2/nofpu/Implies specifies nonexistent powerpc/powerpc32/soft-fp
How does it work?
