It would be nice to goup and set cpu features as CPU_FEATURES="mmx sse sse2".
Can you please move the USE="mmx sse sse2" and others to an expanded use?
The second idea is to implement CPU_FEATURES="native" that auto-detects the features supported by local /proc/cpuinfo.
don't know why this was bounced to me ...
i think this came up on gentoo-dev at some point. if it didn't, that would be the place to post this idea.
CPU_FEATURES="native" might require PMS support
and it has indeed been argued a couple of times. suggest you review those threads in the archives first before starting a new one so we don't waste time rehashing the same crap.
