Vector expf for x86_64 and tests.
Here is implementation of vectorized expf containing SSE, AVX, AVX2 and AVX512 versions according to Vector ABI <https://groups.google.com/forum/#!topic/x86-64-abi/LmppCfN1rZ4>. * sysdeps/unix/sysv/linux/x86_64/libmvec.abilist: New symbols added. * sysdeps/x86/fpu/bits/math-vector.h: Added SIMD declaration and asm redirections for expf. * 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_s_expf16_core.S: New file. * sysdeps/x86_64/fpu/multiarch/svml_s_expf16_core_avx512.S: New file. * sysdeps/x86_64/fpu/multiarch/svml_s_expf4_core.S: New file. * sysdeps/x86_64/fpu/multiarch/svml_s_expf4_core_sse4.S: New file. * sysdeps/x86_64/fpu/multiarch/svml_s_expf8_core.S: New file. * sysdeps/x86_64/fpu/multiarch/svml_s_expf8_core_avx2.S: New file. * sysdeps/x86_64/fpu/svml_s_expf16_core.S: New file. * sysdeps/x86_64/fpu/svml_s_expf4_core.S: New file. * sysdeps/x86_64/fpu/svml_s_expf8_core.S: New file. * sysdeps/x86_64/fpu/svml_s_expf8_core_avx.S: New file. * sysdeps/x86_64/fpu/svml_s_expf_data.S: New file. * sysdeps/x86_64/fpu/svml_s_expf_data.h: New file. * sysdeps/x86_64/fpu/test-float-vlen16-wrappers.c: Vector expf tests. * sysdeps/x86_64/fpu/test-float-vlen16.c: Likewise. * sysdeps/x86_64/fpu/test-float-vlen4-wrappers.c: Likewise. * sysdeps/x86_64/fpu/test-float-vlen4.c: Likewise. * sysdeps/x86_64/fpu/test-float-vlen8-avx2-wrappers.c: Likewise. * sysdeps/x86_64/fpu/test-float-vlen8-avx2.c: Likewise. * sysdeps/x86_64/fpu/test-float-vlen8-wrappers.c: Likewise. * sysdeps/x86_64/fpu/test-float-vlen8.c: Likewise. * NEWS: Mention addition of x86_64 vector expf.
