While investigating my bug (skia:4052) I saw this TODO and figured it'd make me feel better about an otherwise unsuccessful investigation. This speeds up HardLight and Overlay (same code) by about 15% with SSE, mostly by rewriting the logic from 1 cheap comparison and 2 expensive div255() calls to 2 cheap comparisons and 1 expensive div255(). NEON speeds up by a more modest ~3%. BUG=skia: Review URL: https://codereview.chromium.org/1230663005 |
