From 6af25acc7b6313fd8934c3b2f0eb3da5a1c6eb6b Mon Sep 17 00:00:00 2001 From: Andrew Senkevich Date: Wed, 17 Jun 2015 15:38:29 +0300 Subject: Vector log for x86_64 and tests. Here is implementation of vectorized log containing SSE, AVX, AVX2 and AVX512 versions according to Vector ABI . * bits/libm-simd-decl-stubs.h: Added stubs for log. * math/bits/mathcalls.h: Added log declaration with __MATHCALL_VEC. * sysdeps/unix/sysv/linux/x86_64/libmvec.abilist: New versions added. * sysdeps/x86/fpu/bits/math-vector.h: Added SIMD declaration and asm redirections for log. * sysdeps/x86_64/fpu/Makefile (libmvec-support): Added new files. * sysdeps/x86_64/fpu/Versions: New versions added. * sysdeps/x86_64/fpu/libm-test-ulps: Regenerated. * sysdeps/x86_64/fpu/multiarch/Makefile (libmvec-sysdep_routines): Added build of SSE, AVX2 and AVX512 IFUNC versions. * sysdeps/x86_64/fpu/multiarch/svml_d_log2_core.S: New file. * sysdeps/x86_64/fpu/multiarch/svml_d_log2_core_sse4.S: New file. * sysdeps/x86_64/fpu/multiarch/svml_d_log4_core.S: New file. * sysdeps/x86_64/fpu/multiarch/svml_d_log4_core_avx2.S: New file. * sysdeps/x86_64/fpu/multiarch/svml_d_log8_core.S: New file. * sysdeps/x86_64/fpu/multiarch/svml_d_log8_core_avx512.S: New file. * sysdeps/x86_64/fpu/svml_d_log2_core.S: New file. * sysdeps/x86_64/fpu/svml_d_log4_core.S: New file. * sysdeps/x86_64/fpu/svml_d_log4_core_avx.S: New file. * sysdeps/x86_64/fpu/svml_d_log8_core.S: New file. * sysdeps/x86_64/fpu/svml_d_log_data.S: New file. * sysdeps/x86_64/fpu/svml_d_log_data.h: New file. * sysdeps/x86_64/fpu/test-double-vlen2-wrappers.c: Added vector log test. * sysdeps/x86_64/fpu/test-double-vlen2.c: Likewise. * sysdeps/x86_64/fpu/test-double-vlen4-avx2-wrappers.c: Likewise. * sysdeps/x86_64/fpu/test-double-vlen4-avx2.c: Likewise. * sysdeps/x86_64/fpu/test-double-vlen4-wrappers.c: Likewise. * sysdeps/x86_64/fpu/test-double-vlen4.c: Likewise. * sysdeps/x86_64/fpu/test-double-vlen8-wrappers.c: Likewise. * sysdeps/x86_64/fpu/test-double-vlen8.c: Likewise. * NEWS: Mention addition of x86_64 vector log. --- sysdeps/x86/fpu/bits/math-vector.h | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'sysdeps/x86/fpu/bits') diff --git a/sysdeps/x86/fpu/bits/math-vector.h b/sysdeps/x86/fpu/bits/math-vector.h index 2b739c5444..ed85622560 100644 --- a/sysdeps/x86/fpu/bits/math-vector.h +++ b/sysdeps/x86/fpu/bits/math-vector.h @@ -36,5 +36,17 @@ # define __DECL_SIMD_sin __DECL_SIMD_x86_64 # undef __DECL_SIMD_sinf # define __DECL_SIMD_sinf __DECL_SIMD_x86_64 +# undef __DECL_SIMD_log +# define __DECL_SIMD_log __DECL_SIMD_x86_64 + +/* Workaround to exclude unnecessary symbol aliases in libmvec + while GCC creates the vector names based on scalar asm name. + Corresponding discussion started at + . */ +__asm__ ("_ZGVbN2v___log_finite = _ZGVbN2v_log"); +__asm__ ("_ZGVcN4v___log_finite = _ZGVcN4v_log"); +__asm__ ("_ZGVdN4v___log_finite = _ZGVdN4v_log"); +__asm__ ("_ZGVeN8v___log_finite = _ZGVeN8v_log"); + # endif #endif -- cgit 1.4.1
