What is the current status of AMD K6 optimization in egcs/pgcc? 
Information on this subject seems virtually nonexistent.  What I have
gleaned about it amounts to this recommendation:

gcc -O6 -mamdk6 -fno-software-pipe -fno-swap-for-agi
-fno-schedule-stack-reg-insns -fno-exceptions 

I am running redhat 5.0 (glibc2) and am specifically interested in
optimizing Mesa, which is an OPENGL compatible graphics library.  It is
fpu intensive and I notice that there are some recommendations for fpu
intensive programs in the FAQ.  I have compiled the library in the past
with "-O6 -mamdk6" and found it to be slightly slower than standard gcc
2.7.*.  Does anyone have any recommendations?  

-Thank You,
