Rod, The question was not whether one can optimize for Pentium but whether one can optimize for AMD and that's not an option on most commercial compilers. I think K6 and M2 are "optimized" to run normal code that compilers produce. The analysis of real-world applications went ino the design of K6 and M2. This is why they beat Pentium MMX on most real world test. It seems that Pentiums are optimized to run some obscure benchmarks well, (or to put it another way, there are some obscure benchmarks out there that are optimized for Pentium.) Joe

Rod, <even if one could optimize for the K6 you would have to support separate binaries.> Please try to understand the following: a) the separate binaries were always "supported", under different flavors like new (upgraded) DLLs and device drivers. You can install and uninstall drivers. Easily. People do this almost every time when installing new game or piece of other software. For your education, the typical "application" code is mostly a bunch of calls to theses DLLs and system drivers, nothing more. b) there is no big need in special K6 optimization. You just DO NOT need to OPTIMIZE FOR PENTIUM, to avoid special FXCH additions and other tricks. And the K6 will perform "much" better on floating side. Remember, we are talking here about plus-minus 20% in performance difference to shut down your whinning about sluggish FPU performance of K6. c) now try to think who's arguments are silly.
