Proposal & patch : SDL_cpu


Recently, I’ve seen patches posted on this mailing list that needed cpu
features detection (esp mmx detection).
I’ve had this idea for some time now, and here is my try at it :
SDL_cpu. This is a small patch that adds cpu features detection to SDL
through a simple function :
SDL_CpuHasFeature(requested_feature). For example,
SDL_CpuHasFeature(SDL_CPU_X86_MMX) returns wether the cpu is mmx-capable.

If it’s accepted I’ll start integrating patches using this interface and
then submit them to this list.
