Hi,

building llvm-3.2 on powerpcspe [1] currently results in:

I'm attaching a patch that fixes this by excluding powerpc floating point
register save/restore asm on powerpcspe where those registers don't exist.

The patch also fixes the same issue in llvm-2.9, llvm-3.0 and llvm-3.1. Please
include it there, also. I can file separate bugs there, if necessary.

Thanks,

Roland
