Is there a noticeable difference in speed anyway? With mcpu > I would not have the trouble I am having now... Your trouble started, when you switched to a completly different cpu... mcpu = only rearranging stuff so it might run better on the cpu specified. No instructions and features used, that are not available on all the other cpus from a family (in theory, a binary built with mcpu=athlon-xp should be able to run on a i486). march = optimizing for the specified cpu. Using all features and instructions available, building stuff not able to run on other cpus. (so a resulting binary of march=athlon-xp won't run on a i486) usually march is faster on the given cpu, mcpu is more compatible. -- [EMAIL PROTECTED] mailing list
