Re: PATCH: optimized expf for x86_32

Hello,

Code was replaced to sysdeps/i386/i686/multiarch. New patch is attached.

I wonder whether this shouldn't be sysdeps/i386/i686/fpu/multiarch - this is at least in agreement what we do with sparc and x86-64.

My performance data was about  { expf (which uses __ieee754_expf),
__ieee754_expf } not about  { __expf_finite, __ieee754_expf }. Sorry
for misprint in names at my previous letter.
We didn't check __expf_finite but believe it becomes faster as well.
