[LLVMdev] llc assertion failure

[Ryan M. Lefever]

I am running the following llvm-ld command to produce native code:

llvm-ld -native -o code.exe code.bc   -lm

However, I am getting the following assertion failure in llc.  The 
bytecode has been processed with opt, it passes opt bytecode 
verification.  I'm not too familiar with backend code generation.  Does 
anyone have any insight in to what the problem might be or how to go 
about debugging it?

Regards,
Ryan
