Summary: llvm-gcc miscompiles LLVM on powerpc-apple-darwin9
Product: new-bugs
Version: unspecified
Platform: PC
OS/Version: All
Status: NEW
Severity: normal

I recently switched the smooshlab powerpc-apple-darwin9 to do a two stage LLVM
build. The second build of LLVM (Release, using the stage one llvm-gcc) fails
to pass the tests because tblgen is crashing in the LLVMC tests:

It looks like LLVM (stage 2) is getting miscompiled.
