Re: subarchitectures (was Re: What to do with optimization flags ? )
Greetings! Remember this old post? Well, things are just about done
with atlas now. Problem is, potato ldso searches only ix86 and
ix86/mmx, where x is correctly chosen according to the running
processor, but mmx is the only subdirectory searched on athlon, p3,
p2, k6 ...
Any suggestions?
Thanks for your work on Debian!
