Hello Andrew,
very nice work!
But can you please redo your patch against the real Mesa-3.5 CVS tree and not
yours?
src/X86/3dnow_xform3.S
src/X86/3dnow_xform4.S
fail.
As I "see" that you are very good x86 asm hacker and I am not (I learned asm
on 6502 and 68k) what do you think about working together on the outstanding
Glide3 3DNow! bugs?
I have Glide3 for the Voodoo5 working with 3DNow! but one (?) bug still
persists.
You can trigger it with texdown.

You can not build Glide3 with 3DNow! acceleration the "normal" way:
./chores.3dfx --clean --generate --configure=--enable-amd3d --build
'cause something in the build system (configuration) is broken. If you do it
this way you will get a much bigger lib in which one 3DNow_MMX token is
undefined.

More after the weekend 'cause I am in transition to SuSE Linux 7.3 (German
version only at the moment, sorry) of course with an updated kernel ;-)
Please forward this to the Mesa List 'cause Geocrawler sucks.
Greetings,
Dieter
