_mm_mulhi_epu16 makes the (...*257)>>16 part simple. This seems to speed up every transfermode that uses div255(), in the 7-25% range. It even appears to obviate the need for approxMulDiv255() on SSE. I'm not sure about NEON yet, so I'll keep approxMulDiv255() for now. Should be no pixels change: https://gold.skia.org/search2?issue=1452903004&unt=true&query=source_type%3Dgm&master=false BUG=skia: CQ_EXTRA_TRYBOTS=client.skia:Test-Ubuntu-GCC-GCE-CPU-AVX2-x86_64-Release-SKNX_NO_SIMD-Trybot Review URL: https://codereview.chromium.org/1452903004 |
