Adds optimization of Skia S32A_Opaque_Blitrow blitter using SSE4.2 SIMD instruction set. Special case for when alpha is zero or opaque. Performance increase of 10%-400% compared to the existing SSE2 optimization (measured on Silvermont architecture). Noticeable in ~25 different skia bench subtests, especially in bitmap_8888_*, repeatTile_*, and morph_*. bitmap_8888_A - 100% faster bitmap_8888_A_source_transparent - 250% faster bitmap_8888_A_source_opaque - 25% faster bitmap_8888_A_scale_bicubic - 75% faster Signed-off-by: Henrik Smiding <henrik.smiding@intel.com> Committed: https://skia.googlesource.com/skia/+/e2527b147679b0c43019fae7d59cc3777d2d097e Committed: https://skia.googlesource.com/skia/+/b5c281e1e06af3be804309877de1dac6145686b9 R=reed@google.com, mtklein@google.com, tomhudson@google.com, djsollen@google.com, joakim.landberg@intel.com Author: henrik.smiding@intel.com Review URL: https://codereview.chromium.org/289473009 |
