Date: Tue, 30 Mar 2004 21:26:47 -0600 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.
