From: Tyler Montbriand
Subject: [SDL] Opteron MMX patches for SDL_blit.c and SDL_blit_A.c
The inline MMX assembly in SDL_blit.c and SDL_blit_A.c compiles and runs fine
unmodified under AMD Opteron. The inline assembly in SDL_yuv_mmx.c and
SDL_blit_N.c unfortunately isn't directly compatible.
I've included diffs from SDL_blit.c and SDL_blit_A.c that allow the MMX
assembly to be compiled when USE_ASMBLIT, __x86_64__, and __GNUC__ are all
defined. All I had to modify was typedefs, the inline assembly itself wasn't
touched.

| 2 All: | |
| 3 Audio rate conversion is only implemented by multiplying or dividing | |
| 4 by a power of two. This is a side-effect of the requirement that the | |
| 5 raw audio buffer size be a power of two, and can hopefully be fixed. | |
| 6 This means 8 KHz audio converted to 22 KHz ends up being 16 KHz. :-/ | |
| 7 | |
| 8 When the implementation is writing directly to video memory the mouse | |
| 9 cursor doesn't work properly. Applications which do this should use | |
| 10 their own mouse cursor and call SDL_ShowCursor(0) to hide the system | |
| 11 cursor. | |
| 12 | |
| 13 Linux: | |
| 14 Wide UNICODE character input (Kanji, etc.) is not yet supported. | |
| 15 It requires handling of keyboard mapping events and using the XIM | |
| 16 input translation extension. I will implement it as requested. | |
| 17 Latin-1 keyboard input works fine. | |

| 0 | 21 The AAlib, GGI, and SVGAlib video drivers are not heavily tested. |
| 22 | |
| 23 Win32: | |
| 24 The MCI driver can't tell if the CD-ROM drive is paused or stopped. | |
| 25 | |
| 26 The SDL_INIT_EVENTTHREAD flag is not supported on Win32 | |
| 27 (Idea: create a separate DirectInput polling thread) | |
| 28 The main purpose of this flag is for smooth cursor motion in | |
| 29 fullscreen environments. | |
| 30 | |
| 31 Wide UNICODE character input (Kanji, etc.) is not yet supported. | |
| 32 This requires the ToUnicode() API which is only implemented on | |
| 33 Windows NT/2000, not on Windows 95/98. | |
| 34 Latin-1 keyboard input works fine. | |
| 35 | |
| 36 Joysticks are only supported under the Win32 MultiMedia API, | |
| 37 DirectInput support is not yet implemented. | |
| 38 | |
| 39 BeOS: | |
| 40 BePPC is not supported, apparently not even by Be Inc. | |
| 41 | |
| 42 SDL_WM_GrabInput() is not implemented. | |
| 43 Does anyone know how to do this? SDL_WM_GrabInput() is designed | |
| 44 to prevent the user from switching input and mouse focus away from | |
| 45 the SDL application. | |
| 46 | |
| 47 Continuous relative mouse motion is not implemented. | |
| 48 | |
| 49 Wide UNICODE character input (Kanji, etc.) has not been tested. | |
| 50 Latin-1 keyboard input works fine. | |
| 51 | |
| 52 MacOS: | |
| 53 Palette handling isn't implemented in windowed mode yet. | |
| 54 | |
| 55 Audio hasn't been extensively tested, in particular the locking | |
| 56 isn't implemented and mixer routines may not call malloc() or free() | |
| 57 because they are called at interrupt time. | |
| 58 | |
| 59 SDL_WM_GrabInput() is not implemented. | |
| 60 Does anyone know how to do this? SDL_WM_GrabInput() is designed | |
| 61 to prevent the user from switching input and mouse focus away from | |
| 62 the SDL application. | |
| 63 | |
| 64 Continuous relative mouse motion is not implemented. | |
| 65 | |
| 66 SDL_AddTimer() and SDL_RemoveTimer() haven't been implemented yet. | |
| 67 | |
| 68 Not all of the keys are properly recognized on the keyboard. | |
