Subject: SDL Patch
Hio,
I saw your last call on the mailing list. Here's a patch which I
submitted about two weeks ago which hasn't made it in.
In the current sdl.m4, there's a bug where if your configure.ac, you
have AC_LANG(C++) specified, it won't properly compile and link the SDL
test program when you run the configure script. This is because only the
default CFLAGS is overriden in sdl.m4, and in the patch below, I've
fixed it so it overrides CXXFLAGS as well, allowing it to work with g++.

| 71 This MMX assembler is my first assembler/MMX program ever. | |
| 72 Thus it maybe buggy. | |
| 73 Send patches to: | |
| 74 mvogt@rhrk.uni-kl.de | |
| 75 | |
| 76 After it worked fine I have "obfuscated" the code a bit to have | |
| 77 more parallism in the MMX units. This means I moved | |
| 78 initilisation around and delayed other instruction. | |
| 79 Performance measurement did not show that this brought any advantage | |
| 80 but in theory it _should_ be faster this way. | |
| 81 | |
| 82 The overall performanve gain to the C based dither was 30%-40%. | |
| 83 The MMX routine calculates 256bit=8RGB values in each cycle | |
| 84 (4 for row1 & 4 for row2) | |
| 85 | |
| 86 The red/green/blue.. coefficents are taken from the mpeg_play | |
| 87 player. They look nice, but I dont know if you can have | |
| 88 better values, to avoid integer rounding errors. | |
| 89 | |

| 93 | |
| 94 It is a requirement that the cr/cb/lum are 8 byte aligned and | |
| 95 the out are 16byte aligned or you will/may get segfaults | |
