* SSE 4.1 SrcOver blits: color32, blitmask.Gravatar mtklein2015-12-16
| | | | | | | | | | | | | | | | | | | | | | | | This is mainly warmup for an AVX2 version. The machine I'm typing this on just doesn't support AVX2. This strategy should translate easily down to SSSE3 and SSE2. Xfermode_SrcOver: 2.73ms -> 2.62ms (0.96x) (That's Color32.) Xfermode_SrcOver_aa: 3.48ms -> 3.09ms (0.89x) (That's BlitMask_D32_A8.) AA text blits (text_16_AA_{88,FF,WT,BK}) show speedups in the range of 5 to 20%. Unlike previous versions of this code, all the div255() are exactly (x+127)/255. This won't fix any major bugs, but it does correct our bias in the middle. There will be many diffs, all minor. I've punted for now on pmaddubsw for lerping. I do intend to try that, but I want this (relatively simple) code as my basis for comparison.

* Update SkOpts namespaces.Gravatar mtklein2015-08-18
| | | | | | | | portable -> default, and everyone gets an sk_ prefix. BUG=skia:4117 Review URL: https://codereview.chromium.org/1299013003
* Port morphology to SkOpts.Gravatar mtklein2015-08-04
| | | | | | | | | | | | Nothing too fancy. Direction enums become enum classes so they don't get all confused. An alternative is to create one single Direction enum that both blur and morphology opts use. BUG=skia:4117 Review URL: https://codereview.chromium.org/1267343004
* Reorganize to keep similar code together.Gravatar Mike Klein2015-08-04
| | | | | | | | | This organizes memset16, memset32, and rsqrt the same way as the other code. No functional change. BUG=skia:4117 R=djsollen@google.com Review URL: https://codereview.chromium.org/1264423002 .
* Port SkBlurImage opts to SkOpts.Gravatar mtklein2015-08-04
| | | | | | | | | | | | +268 -535 lines I also rearranged the code a little bit to encapsulate itself better, mostly replacing static helper functions with lambdas. This also let me merge the SSE2 and SSE4.1 code paths. BUG=skia:4117 Review URL: https://codereview.chromium.org/1264103004
