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.

Wish list for the 1.3 development branch: * Use /etc/fb.modes, if available, like GGI does * Add mousewheel events (new unified event architecture?) * DirectInput joystick support needs to be implemented * Be able to enumerate and select available audio and video drivers * Fullscreen video mode support for MacOS X * Explicit vertical retrace wait (maybe separate from SDL_Flip?) * Shaped windows, windows without borders * Multiple windows, multiple display support * SDL_INIT_EVENTTHREAD on Windows and MacOS? * Add a timestamp to events * Use RDTSC for timer resolution on x86 hardware * Add audio input API * Add hardware accelerated scaled blit * Add hardware accelerated alpha blits * Redesign blitting architecture to allow blit plugins In the jump from 1.2 to 1.3, we should change the SDL_Rect members to int and evaluate all the rest of the datatypes. This is the only place we should do it though, since the 1.2 series should not break binary compatibility in this way. Requests: * PCM and CDROM volume control (deprecated, but possible)
