* sysdeps/x86_64/fpu/bits/mathinline.h: Add fmax and fmin optimizations
for __FINITE_MATH_ONLY__ == 1.
2011-09-15 Andreas Schwab <schwab@redhat.com>
* sysdeps/powerpc/fpu/e_hypot.c (__ieee754_hypot): Use
__ieee754_sqrt instead of sqrt.
* sysdeps/powerpc/fpu/e_hypotf.c (__ieee754_hypotf): Use
__ieee754_sqrtf instead of sqrtf.
* sysdeps/powerpc/fpu/e_rem_pio2f.c (__ieee754_rem_pio2f): Use
__floorf instead of floorf.
* sysdeps/powerpc/fpu/k_rem_pio2f.c (__fp_kernel_rem_pio2f): Use
__floorf, __truncf instead of floorf, truncf.
2011-09-14 Ulrich Drepper <drepper@gmail.com>
