| | | | | | | | | | | | | | | | | | | | | General cleanup of optimization files for x86/SSEx. Renamed the opts_check_SSE2.cpp file to _x86, since it's not specific to SSE2. Commented out the ColorRect32 optimization, since it's disabled anyway, to make it more visible. Also fixed a lot of indentation, inclusion guards, spelling, copyright headers, braces, whitespace, and sorting of includes.

* ARM Skia NEON patches - 35 - First AArch64 supportGravatar commit-bot@chromium.org2014-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Aarch64 support This change contains the necessary modifications to have Skia build and run properly on an ARMv8 processor in aarch64 execution state. Here's a list of the changes: - add an arm64 target to the build system + SK_CPU_ARM64 flag - MatrixTest was failing when built in Release mode. Fused MAC instructions were generated which made some intermediate results more accurate. As the test relies on result comparison, the more precise results when compared to others led to a gap bigger than what was tolerated. As I don't know if some actual skia code relies on results being comparable, I've disabled fused MAC instruction with -ffp-contract=off for arm64. - Modify include/core/SkOnce.h to have barriers work. - SK_CPU_ARM64 implies SK_ARM_NEON_MODE_ALWAYS. - use existing Xfermode optimisations with modifications that can be removed in the future when toolchains are ready. Also save a few instructions is two Xfermodes (will apply to ARM too). - use existing SkBoxBlur and SkMorphology optimisations. - use existing SkBlitMask optimisations - use existing BitmapProcState and Convolution optimisations. Future changes will include: - Blitters (only partialy merged upstream) - SkUtils (there's little value in sending asm optimisations without having them benchmarked on real hardware).

* ARM Skia NEON patches - 20 - New improved BitmapProcState codeGravatar commit-bot@chromium.org2014-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | BitmapProcState: new factorised code This one basically factorises the clamp and repeat transformations with some performance improvements. It has the benefit of being faster, much easier to maintain (nearly three times less code for more work done :-)), and more complete (all persp transformations weren't optimised in the previous version). It also introduces the use of can_truncate_to_fixed_for_decal where useful. The effect on benchmarks ranges from a 5% penalty to a 25% gain on a Cortex-A9 and from a 5% penalty to a 100% gain on a Cortex-A15.

This gives a 3-5X speedup over the naive implementation, and also mitigates a timing-based security attack in Chrome (https://code.google.com/p/chromium/issues/detail?id=251711).
