Sam Lantinga 6e35e42145 Working on bug 3921 - Add some Fastpath to BlitNtoNKey and BlitNtoNKeyCopyAlpha 
Sylvain

I did various benches. with clang 6.0.0 on linux, and ndk-r16b on android (NDK_TOOLCHAIN_VERSION=clang).

- still see a x10 speed factor.
- with duff_loops, it does not use vectorisation (but doesn't seem to be a problem).

on linux my patch is already at full speed on -O2, whereas the duff_loops need -O3 (200 ms at -03, and 300ms at -02).

I realized that on Android, I had a slight variation which fits best.
both on linux with -O2 and -O3, and on android with 02/03 and armeabi-v7a/arm64.

Here's the patch.

Ozkan Sezer 922623e1b6 SDL_blit_N.c (BlitNtoNKeyCopyAlpha): fix -Wshadow warnings by adding _ 
suffix to the temp Pixel local in the DUFFS_LOOP.
SDL_blit.h (ASSEMBLE_RGB):  add _ prefix to temp Pixel locals to avoid
  any possible shadowings.


The warnings were like the following:

    Added SDL_AUDIO_ALLOW_SAMPLES_CHANGE flag enabling users of SDL_OpenAudioDevice to get

    delta
