Regardless, if OSX no longer supports whichever buggy processors it were that Jonas mentioned, it would be nice to have a compiler option that would get rid of those 'frsp's.

For that, you'll have to wait until it no longer supports the G3 nor the G4 :) It seems to be fixed in the G5 (the 970 at least, don't have a 970FX system to test), and I understood from the message I forwarded it only first appeared on the G3. I can reproduce it on my iBook/G4 1GHz.

Dang. I hate backwards compatibility.

Then again, given that G5-exclusive code is likely to become somewhat common (dedicated 64-bit code paths, etc.), such a G5-specific compiler option might still make sense, as long as there's some assurance the bug won't be reintroduced...

What other annoying processor bugs are lurking out there?
