From 377ed004f2c5b498e0620426a0af447172351f35 Mon Sep 17 00:00:00 2001 From: Andrew Senkevich Date: Mon, 7 Dec 2015 21:58:26 +0300 Subject: Utilize x86_64 vector math functions w/o -fopenmp. This patch allows to use x86_64 vector math functions with GCC 6.* without OpenMP SIMD constructs. For additional details please visit . * sysdeps/x86/fpu/bits/math-vector.h: W/o -fopenmp declare vector math functions with GCC 6.* __attribute__ ((__simd__)). --- sysdeps/x86/fpu/bits/math-vector.h | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'sysdeps') diff --git a/sysdeps/x86/fpu/bits/math-vector.h b/sysdeps/x86/fpu/bits/math-vector.h index f3bfb86..495e895 100644 --- a/sysdeps/x86/fpu/bits/math-vector.h +++ b/sysdeps/x86/fpu/bits/math-vector.h @@ -28,6 +28,12 @@ # if defined _OPENMP && _OPENMP >= 201307 /* OpenMP case. */ # define __DECL_SIMD_x86_64 _Pragma ("omp declare simd notinbranch") +# elif __GNUC_PREREQ (6,0) +/* W/o OpenMP use GCC 6.* __attribute__ ((__simd__)). */ +# define __DECL_SIMD_x86_64 __attribute__ ((__simd__ ("notinbranch"))) +# endif + +# ifdef __DECL_SIMD_x86_64 # undef __DECL_SIMD_cos # define __DECL_SIMD_cos __DECL_SIMD_x86_64 # undef __DECL_SIMD_cosf -- cgit v1.1
