RE: Powerpc signal handler with floating point registers



To answer my own question, apparently not.
Though for some odd reason it rings a bell. Hmmmmm. Prior release?
Do they get used for anything besides 'long long' operations?

That seems to be a rather big hammer to smash that fly.  Any other
way to make moves not use FP?  Allow floating point, but only if
the program is using floating point types.
