If using -fast as a compiler option, __frsqrte and __frsqrtes (from
ppc_intrinsics) become undefined. I'm not sure why; I'm hoping it's
NOT because they aren't supported on the G5 (would kill a bunch of my
code!)
Anybody know why, off hand? I've parred down what -fast sets to the
set I'm interested in, so it's not a big deal (i.e., I can tell you
what it's not!)
Why messing around to find out why, I noticed that there's a 3.3 and
3.3-fast folder gcc\darwin. What's the difference?
