AboutLinux.com: Optimizing for the Athlon (egcs under RedHat 6)

[ Thanks to Bill Henning for this link. ]

"Recently I wrote a review (at CPUReview) of Linux running on an Athlon 600 based system. While the benchmark results I obtained for that review were excellent; I could not help but feel that the scores could be higher... and egcs has all those nice optimization flags..."

"I decided to run a series of experiments; covering the spectrum from no optimization... to the equivalent of a K7-720 for memory and integer oriented code - and by following the optimization settings shown in the article, you can get up to 73% improvement on some types of code."

"EGCS developers should take note of these results; the best (overall) performing configuration did not turn in the best results for all tests; therefore examining the optimization settings show here and the code for the benchmarks can tell them what sections of the code generator and optimizer need to be tweaked to produce even better Athlon results!
