Total System Recompile

---

So, I decided some days ago I would do something extremely crazy and completely recompile my entire system. Seems logical enough, considering I’m running Gentoo and it’s never a bad idea to emerge -e world.

…Well, except when it is.

I’m testing a goodly number of experimental and not reccommended CFLAGS for recompiling my system, and they seem to be giving me a slight amount of trouble. Particularly the flag “-mregparm=3″, which causes variables to be passed through registers, presumably speeding things up. This causes binary incompatability, resulting in segfaults and overall breakage. The other experimental flags such as -ffast-math and -m128bit-long-double (which also creates binary incompatability) aren’t helping me much here :)

I expect to earn a 5-12% increase in speed from this recompile. For the interested, my make.conf is available here.
