In addition to what John asked, can you say HOW it's failing?  Does the
program crash?  Does the register allocator crash (ie, does llc crash)?

Can you send the output of 'llc -o - foo.bc -debug -print-machineinstrs'?

No need to try all of them, just make sure the default allocator works.
If I remember right, you were having problems even with "hello world" type
of programs, so I don't think it's your code.

In any case, this is really distressing, and I would like to get this
resolved!  :)
