Ah, I'd was curious why there'd been no cvs updates in so long! It the experimental-1 branch where development occurs, then? A note about this on the website would be helpful! Is this a reason to avoid my patch? I've only done one test, the pulsar demo from xscreensavers, but the glx module was some 20% faster in software mode including asm_mmx.c. Not so bad. OTOH, you're right: I don't see a reference to it in the mesa Makefile. We were just copying the glx module Imakefile; perhaps it's out of date. > It should work once like this: > > For a x86 target, cmopile with -DUSE_X86_ASM -DUSE_MMX_ASM > -DUSE_3DNOW_ASM.

Yes, this makes more sense. We just weren't being so sophisticated. :) This is mostly a problem for people building binaries, IMO, which hasn't been our primary focus so far. We aneed to do something similar to support multiple hardware drivers in the same binary. > Please contact also Thomas Tanner, who is trying to write autoconf support > for Mesa. I'll take a look at what he's done. Sounds like we've got more running to do to keep up with you guys!
