Hi,
I am working on optimizations specific for AMD processors. I am sorry that
the K6 optimization present in 3.0.0 is broken. I didn't tested that chip
for a while and didn't noticed that the problem still remain.
I've sent fixes to instruction length estimation code about year ago,
but it didn't get reviewed. I will dig these out and update.
I will try to reproduce that compiler crash reported.
Concerning Athlon optimizations, these should be stable to my best knowledge.
I've compiled quite a lot of code with them w/o problem and got improvements
over i686 and i586 tunning. I would like to hear about any problem with
that settings.
Concerning the Athlon optimizations, I am still working on them and hope to
implement more support (3dnow, etc.) for next gcc release.
