From 5ae4fe60e68a6698afadbec00481be96096e3eb4 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Fri, 14 Nov 2014 18:53:07 +0000 Subject: Remove x86_64 __GNUC_PREREQ (4, 6) conditional. This patch removes a conditional on __GNUC_PREREQ (4, 6) in x86_64 code. Tested for x86_64 that installed shared libraries are unchanged by this patch. Committed (I think this file reasonably comes under math maintainership). * sysdeps/x86_64/fpu/dla.h [__FMA4__ && __GNUC_PREREQ (4, 6)] (DLA_FMS): Make definition conditional only on [__FMA4__]. [__FMA4__ && !__GNUC_PREREQ (4, 6)] (DLA_FMS): Remove conditional definition. --- sysdeps/x86_64/fpu/dla.h | 11 +---------- 1 file changed, 1 insertion(+), 10 deletions(-) (limited to 'sysdeps/x86_64') diff --git a/sysdeps/x86_64/fpu/dla.h b/sysdeps/x86_64/fpu/dla.h index fa2d52bbf0..688efa0f5b 100644 --- a/sysdeps/x86_64/fpu/dla.h +++ b/sysdeps/x86_64/fpu/dla.h @@ -1,17 +1,8 @@ #include #ifdef __FMA4__ -# if __GNUC_PREREQ (4, 6) -# define DLA_FMS(x,y,z) \ +# define DLA_FMS(x,y,z) \ __builtin_fma (x, y, -(z)) -# else -# define DLA_FMS(x,y,z) \ - ({ double __z; \ - asm ("vfmsubsd %3, %2, %1, %0" \ - : "=x" (__z) \ - : "x" ((double) (x)), "xm" ((double) (y)) , "x" ((double) (z))); \ - __z; }) -# endif #endif #include "sysdeps/ieee754/dbl-64/dla.h" -- cgit 1.4.1
