From 24a2718f595bc11dc6abb31303ceb8fdcb664f2f Mon Sep 17 00:00:00 2001 From: Andrew Senkevich Date: Tue, 9 Jun 2015 14:51:52 +0300 Subject: Addition of testing infrastructure for vector math functions. We test vector math functions using scalar tests infrastructure with help of special wrappers from scalar versions to vector ones. Wrapper implemented using platform specific vector types and placed in separate file for compilation with architecture specific options, main part of test has no such options. With help of system of definitions unfolding of which is drived from test code we have wrapper called in individual testing function instead of scalar function. Also system of definitions includes generated during make check header math/libm-have-vector-test.h with series of conditional definitions which help to avoid build fails for functions having no vector versions; runtime architecture check to prevent runtime fails of test run on inappropriate hardware. * math/Makefile: Added rules for vector tests. * math/gen-libm-have-vector-test.sh: Added generation of wrapper declaration under condition. * math/test-double-vlen2.h: New file. * math/test-double-vlen4.h: New file. * math/test-double-vlen8.h: New file. * math/test-vec-loop.h: Added initialization macro. * sysdeps/x86_64/fpu/Makefile: Added variables for vector tests. * sysdeps/x86_64/fpu/libm-test-ulps: Regenarated. * sysdeps/x86_64/fpu/math-tests-arch.h: New file. * sysdeps/x86_64/fpu/test-double-vlen2-wrappers.c: New file. * sysdeps/x86_64/fpu/test-double-vlen2.c: New file. * sysdeps/x86_64/fpu/test-double-vlen4-avx2-wrappers.c: New file. * sysdeps/x86_64/fpu/test-double-vlen4-avx2.c: New file. * sysdeps/x86_64/fpu/test-double-vlen4-wrappers.c: New file. * sysdeps/x86_64/fpu/test-double-vlen4.c: New file. * sysdeps/x86_64/fpu/test-double-vlen8-wrappers.c: New file. * sysdeps/x86_64/fpu/test-double-vlen8.c: New file. --- sysdeps/x86_64/fpu/Makefile | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) (limited to 'sysdeps/x86_64/fpu/Makefile') diff --git a/sysdeps/x86_64/fpu/Makefile b/sysdeps/x86_64/fpu/Makefile index 2f16323f78..2d5fcf894c 100644 --- a/sysdeps/x86_64/fpu/Makefile +++ b/sysdeps/x86_64/fpu/Makefile @@ -3,3 +3,23 @@ libmvec-support += svml_d_cos2_core svml_d_cos4_core_avx \ svml_d_cos4_core svml_d_cos8_core \ svml_d_cos_data init-arch endif + +# Variables for libmvec tests. +ifeq ($(subdir),math) +ifeq ($(build-mathvec),yes) +libmvec-tests += double-vlen2 double-vlen4 double-vlen4-avx2 + +ifeq (yes,$(config-cflags-avx512)) +libmvec-tests += double-vlen8 +endif + +double-vlen2-arch-ext-cflags = -msse4 +double-vlen4-arch-ext-cflags = -mavx +double-vlen4-arch-ext2-cflags = -mavx2 +double-vlen8-arch-ext-cflags = -mavx512f + +CFLAGS-test-double-vlen4-avx2.c = $(libm-test-vec-cflags) +CFLAGS-test-double-vlen4-avx2-wrappers.c = $(double-vlen4-arch-ext2-cflags) + +endif +endif -- cgit 1.4.1
