* ARM Skia NEON patches - 23 - S32_D565_Opaque_Dither cleanup/bugfix/speedGravatar commit-bot@chromium.org2013-09-18
| | | | | | | | | | | | | | | | | | | | | | | BlitRow565: S32_D565_Opaque_Dither: cleaning / bugfix This patch brings a little code cleaning (spaces/comments) and a little speed improvement (by using post-incrementation in the asm) but more importantly it fixes a bug on Linux. The new code now supports ARGB as well as ABGR. I removed the comment as I have confirmed with benchmarks that this code bring a *massive* (3x-7x) speedup compared to the C code.

* ARM Skia NEON patches - 01 - Simple fixesGravatar commit-bot@chromium.org2013-07-15
| | | | | | | | | | | | | | | | | | | | | | | | This series contains a few fairly non-controversial fixes. Misc: remove dead references to neon 4444 functions Misc: avoid the double _neon_neon suffix in the clamp matrix functions.

This patch moves all NEON-specific code from the source src/opts/SkBlitRow_opts_arm.cpp into a new file that is built as part of the 'opts_arm_neon' static library.
