GCC 3.4/3.3 Optimization Flags
I need to optimize some CPU-Intensive Real-Time software I have running, but I have a few optimization flags missing, those would be :
I have the correct optimization flags for my Athlon-XP which are :

however I need to know the same stuff (if available) for the other processors
but I can't find any similar data for the Pentium 3 and the Pentium-MMX.
I need to know their architecture-specific optimization parametrs to tell gcc to compile with.
