http://cgit.freedesktop.org/gstreamer/common/tree/m4/as-compiler-flag.m4 This seems to be a good example of how to check for the validity of "geode" as an -march and -mtune option. I'm just wondering what would be our correct response in case "geode" is not available? Would perhaps "-march=pentium-mmx -m3dnow" be suitable and usable on older GCC versions or should me simply not attempt to set any optimization if "geode" is not a supported option? > Regarding i686 optimizations that are incompatible with the Geode > instruction set, I'm working on this issue with AMD's GCC team.
