Oh, well, from -O0 and -O3 I really hope there's difference :D But the compilation changes are more like for cache lines and instruction reordering... Someway gcc tuned for the K7 gives bad code for emcmot... or maybe in some way the options are not correctly propagated from the main kernel to the emc build system? I don't know since it doesn't print the effective gcc line in use (I'm sure there's a switch somewhere in the makefile). Anyway, since I still have a lot of cpu to burn, I'm keeping it to pentium classic. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
