recompiling with GCC to get a working llc & bugpoint to narrow it further...

Fixed, testcase here: CodeGen/Generic/fpowi-promote.ll

Patch here:
http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20070226/045469.html

BTW, you'll get much better code out of LLVM if you configure llvm-gcc to produce code for a target with
SSE2.

Thanks,

-Chris

Sorry for the noise, I had rebuilt in the wrong order.
