* Replace SSE optimization of Color32A_D565Gravatar henrik.smiding2015-03-20
| | | | | | | | | | | | | | | | | | | | | | | Adds an SSE2 version of the Color32A_D565 function, to replace the existing SSE4 version. Also does some minor cleanup. Performance improvement in the following Skia benchmarks. Measured on Atom Silvermont: Xfermode_SrcOver - x3 luma_colorfilter_large - x4.6 luma_colorfilter_small - x2 tablebench - ~15% chart_bw - ~10% Measured on Corei7 Haswell: luma_colorfilter_large running SSE2 - x2 luma_colorfilter_large running SSE4 - x2.3 Also improves performance in WPS Office application and 2D subtest of 0xbenchmark on Android.

* SSE4 opaque blend using intrinsics instead of assembly.Gravatar mtklein2015-01-26
Since we had such a hard time with the assembly versions of this blit (to the point that we have them completely disabled everywhere), I thought I'd take a shot at writing a version of the blit using intrinsics. The key feature of SSE4 we're exploiting is that we can use ptest (_mm_test*) to skip the blend when the 16 src pixels we consider each loop are all opaque or all transparent. _mm_shuffle_epi8 from SSSE3 also lends a hand to extract all those alphas. It's worth looking to see if we can backport this type of logic to SSE2 using _mm_movemask_epi8, or up to 32 pixels at a time using AVX. My local performance testing doesn't show this to be an unambiguous win (there are probably microbenchmarks and SKPs where we'd be better off just powering through the blend rather than looking at alphas), but the potential does seem tantalizing enough to let skiaperf vet it on the bots. (< 1.0x is a win.) DM says it draws pixel perfect compare to the old code.
