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, -Steve Bergman
