2000-05-22 Andreas Jaeger <aj@suse.de> * math/Makefile: Add -D__FAST_MATH__ to CFLAGS-test-ifloat.c, CFLAGS-test-idouble.c, CFLAGS-test-ildoubl.c. * manual/math.texi (FP Function Optimizations): Document gcc -ffast-math behaviour with mathinlines. * sysdeps/i386/fpu/bits/mathinline.h: Only use save inline functions unless -ffast-math is given to gcc.
