From: Stefan Klug
Subject: Re: [SDL] SVN doesn't compile for wince
the patch applied for Revision 4483 was seemingly not checked for side
effects.
It broke the WinCE build.
The attached patch should fix these problems. I'm not using SDL 1.2 on
CE anymore, and therefore haven't tested the patch... but at least it
compiles ;-)
Regards Stefan

| 52 This MMX assembler is my first assembler/MMX program ever. | |
| 53 Thus it maybe buggy. | |
| 54 Send patches to: | |
| 55 mvogt@rhrk.uni-kl.de | |
| 56 | |
| 57 After it worked fine I have "obfuscated" the code a bit to have | |
| 58 more parallism in the MMX units. This means I moved | |
| 59 initilisation around and delayed other instruction. | |
| 60 Performance measurement did not show that this brought any advantage | |
| 61 but in theory it _should_ be faster this way. | |
| 62 | |
| 63 The overall performanve gain to the C based dither was 30%-40%. | |
| 64 The MMX routine calculates 256bit=8RGB values in each cycle | |
| 65 (4 for row1 & 4 for row2) | |
| 66 | |
| 67 The red/green/blue.. coefficents are taken from the mpeg_play | |
| 68 player. They look nice, but I dont know if you can have | |
| 69 better values, to avoid integer rounding errors. | |
| 70 | |
| 71 | |
| 72 IMPORTANT: | |
| 73 ========== | |
| 74 | |
| 75 It is a requirement that the cr/cb/lum are 8 byte aligned and | |
| 76 the out are 16byte aligned or you will/may get segfaults | |
