The patch adds new input ranges for the\nbenchtests based on feedback from SPECcpu2017 usage.\n\nThe performance is similar, with some gains and some regressions. The\nx86_64-v1 shows some performance regression because the CORE-MATH\nimplementation relies on roundeven. The x86_64v2 and forward provide\na specific instruction, and x86_64 already provides an FMA ifunc variant.\n\n[1] https://gitlab.inria.fr/core-math/core-math\n\nAdhemerval Zanella (8):\n benchtest: Redefine cosf ranges\n benchtest: Redefine sinf ranges\n benchtest: Redefine sincosf ranges\n math: Use sinf from CORE-MATH\n math: Use cosf from CORE-MATH\n math: Use sincosf from CORE-MATH\n math: Consolidate common definitions for cosf/sinf/tanf/sincosf\n math: Remove unused definitions for sinf/cosf/sincosf implementation\n\n SHARED-FILES | 6 +\n benchtests/cosf-inputs | 5409 ++++++-----\n benchtests/sincosf-inputs | 8309 ++++++-----------\n benchtests/sinf-inputs | 7919 ++++++----------\n math/Makefile | 2 +\n math/auto-libm-test-in | 1 +\n math/auto-libm-test-out-sincos | 25 +\n sysdeps/ieee754/flt-32/libm-test-ulps | 36 +\n sysdeps/ieee754/flt-32/reduce_aux.h | 38 +-\n .../flt-32/reduce_aux_data.c} | 37 +-\n sysdeps/ieee754/flt-32/s_cosf.c | 160 +-\n sysdeps/ieee754/flt-32/s_sincosf.c | 191 +-\n sysdeps/ieee754/flt-32/s_sincosf.h | 95 -\n sysdeps/ieee754/flt-32/s_sincosf_common.c | 90 +\n sysdeps/ieee754/flt-32/s_sincosf_common.h | 63 +\n sysdeps/ieee754/flt-32/s_sincosf_data.c | 157 +-\n sysdeps/ieee754/flt-32/s_sincosf_data.h | 64 +\n sysdeps/ieee754/flt-32/s_sinf.c | 164 +-\n sysdeps/ieee754/flt-32/s_tanf.c | 65 +-\n sysdeps/ieee754/flt-32/sincosf_poly.h | 87 -\n sysdeps/x86/fpu/sincosf_poly.h | 111 -\n 21 files changed, 9752 insertions(+), 13277 deletions(-)\n rename sysdeps/{x86/fpu/s_sincosf_data.c => ieee754/flt-32/reduce_aux_data.c} (58%)\n delete mode 100644 sysdeps/ieee754/flt-32/s_sincosf.h\n create mode 100644 sysdeps/ieee754/flt-32/s_sincosf_common.c\n create mode 100644 sysdeps/ieee754/flt-32/s_sincosf_common.h\n create mode 100644 sysdeps/ieee754/flt-32/s_sincosf_data.h\n delete mode 100644 sysdeps/ieee754/flt-32/sincosf_poly.h\n delete mode 100644 sysdeps/x86/fpu/sincosf_poly.h" }
