H.J. Lu 7eda65f69e i386: Replace assembly versions of e_exp2f with generic e_exp2f.c ... This patch replaces i386 assembly versions of e_exp2f with generic e_exp2f.c. For workload-spec2017.wrf, on Nehalem, it improves performance by: Before After Improvement reciprocal-throughput 112.996 40.0454 182% latency 126.581 54.4479 132% On Skylake, it improves performance by: Before After Improvement reciprocal-throughput 113.14 39.447 186% latency 136.068 55.684 144% On IvyBridge with --disable-multi-arch, it improves performance by: Before After Improvement reciprocal-throughput 132.521 40.3759 228% latency 145.791 58.4587 149% * sysdeps/i386/fpu/e_exp2f.S: Removed. * sysdeps/i386/fpu/w_exp2f.c: Likewise. * sysdeps/i386/fpu/libm-test-ulps: Updated for generic e_exp2f.c. * sysdeps/i386/i686/fpu/multiarch/libm-test-ulps: Likewise. * sysdeps/i386/i686/fpu/multiarch/Makefile (libm-sysdep_routines): Add e_exp2f-sse2. (CFLAGS-e_exp2f-sse2.c): New. * sysdeps/i386/i686/fpu/multiarch/e_exp2f-sse2.c: New file. * sysdeps/i386/i686/fpu/multiarch/e_exp2f.c: Likewise.		2017-10-22 08:00:18 -07:00
