I can now get SDL_cpuinfo.c to detect the AMD Opteron’s RDTSC, MMX, MMXEXT,
3DNOW, 3DNOWEXT, SSE, and SSE2 instruction set extensions under Linux. It
took one #ifdef’ed block of new asm code to account for the 64-bit flags
register, but the other two blocks worked fine without modification, just
needed to modify the #ifdef’s a bit.
I’ve attached the .diff between CVS.
Cheers,
Tyler Montbriand
