Wilco Dijkstra 599cf39766 Improve performance of sinf and cosf ... The second patch improves performance of sinf and cosf using the same algorithms and polynomials. The returned values are identical to sincosf for the same input. ULP definitions for AArch64 and x64 are updated. sinf/cosf througput gains on Cortex-A72: * |x| < 0x1p-12 : 1.2x * |x| < M_PI_4 : 1.8x * |x| < 2 * M_PI: 1.7x * |x| < 120.0 : 2.3x * |x| < Inf : 3.0x * NEWS: Mention sinf, cosf, sincosf. * sysdeps/aarch64/libm-test-ulps: Update ULP for sinf, cosf, sincosf. * sysdeps/x86_64/fpu/libm-test-ulps: Update ULP for sinf and cosf. * sysdeps/x86_64/fpu/multiarch/s_sincosf-fma.c: Add definitions of constants rather than including generic sincosf.h. * sysdeps/x86_64/fpu/s_sincosf_data.c: Remove. * sysdeps/ieee754/flt-32/s_cosf.c (cosf): Rewrite. * sysdeps/ieee754/flt-32/s_sincosf.h (reduced_sin): Remove. (reduced_cos): Remove. (sinf_poly): New function. * sysdeps/ieee754/flt-32/s_sinf.c (sinf): Rewrite.		2018-08-14 10:45:59 +01:00
