Add AVX optimized versions for some x86-64 math functions 2011-10-26 01:34:55 +00:00			`#if defined HAVE_FMA4_SUPPORT \|\| defined HAVE_AVX_SUPPORT`
Optimize accurate 64-bit routines for FMA4 on x86-64 2011-10-25 00:19:17 +00:00			`# include <init-arch.h>`
Fix implicit __isinf declarations in exp. My recent exp patch introduced warnings about implicit __isinf declarations in exp because e_exp.c didn't include <math.h>. This patch fixes this. Because <math.h> can't be included after <math_private.h> (because of macro definitions of __nan), it was necessary to put an include in sysdeps/x86_64/fpu/multiarch/e_exp.c as well. Tested x86_64. sysdeps/ieee754/dbl-64/e_exp.c: Include <math.h>. * sysdeps/x86_64/fpu/multiarch/e_exp.c [HAVE_FMA4_SUPPORT \|\| HAVE_AVX_SUPPORT]: Likewise. 2014-03-24 22:00:32 +00:00			`# include <math.h>`
