Subject: powerpc: add single instruction fabs, fabsf, fma, fmaf, sqrt, sqrtf
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=7c5f3bb955123ba65bbdedee0e4499ef78a5747c;p=android-x86%2Fexternal-musl-libc.git

powerpc: add single instruction fabs, fabsf, fma, fmaf, sqrt, sqrtf

These are only available on hard float target and sqrt is not available
in the base ISA, so further check is used.
