[AD] CPU Detection.

["Jose Antonio Luque" <sask_allegro@xxxxxxxxxx>]

Hi,

the cpu detection is wrong.

 

Only Pentiums X have SSE with this detection rutine, but this is wrong. Some AMD and others machines have a MMX+ extension that is equivalent to SSE. My Duron supports MMX+ and if I enable SSE (out of Allegro) they use the SSE routines. Example: masked_blit16 SSE scores 9600 and masked_blit16 MMX scores 8600, this is a great improvement and others procesors can use this feature.

 

we have to rewrite the cpu detection and why not add some extra information of CPUs as name, L1/L2 size, speed and others.

 

Another thing

    cpu_3dnow=2 is 3DNow!+ or Extended 3DNow! not 3DNow! (test.c bug)

    cpu_sse=1 is SSE/MMX+ (with new detection rutine if you like)

 

I've working in a small program to detect CPU features and can port to Allegro.

 

What do you think?

 

 

Sorry for my english.
