annotate src/video/SDL_yuv_mmx.c @ 2197:2ff40f30af31

Merged r3261:3262 from branches/SDL-1.2: MMX/YUV with __OPTIMIZE__. "Mac OS X/x86 won't build the MMX/YUV inline assembly without optimizations enabled (not enough registers), so for now, we only build it if we see the __OPTIMIZE__ #define, which GCC provides when you build at -O1 or higher."

74212992fb08 Initial revision Sam Lantinga <slouken@lokigames.com> parents: diff changeset	57 After it worked fine I have "obfuscated" the code a bit to have
74212992fb08 Initial revision Sam Lantinga <slouken@lokigames.com> parents: diff changeset	58 more parallism in the MMX units. This means I moved
74212992fb08 Initial revision Sam Lantinga <slouken@lokigames.com> parents: diff changeset	59 initilisation around and delayed other instruction.
74212992fb08 Initial revision Sam Lantinga <slouken@lokigames.com> parents: diff changeset	60 Performance measurement did not show that this brought any advantage
74212992fb08 Initial revision Sam Lantinga <slouken@lokigames.com> parents: diff changeset	61 but in theory it _should_ be faster this way.
