[LLVMdev] lli aborts on arm QEMU

ARM JIT was able to run the entire llvm test suite when I left it a  
few months ago. "Hello world" should definitely work. It's possible it  
has been broken. But It's equally as likely llvm itself is miscompiled.

There really isn't a way to tell unless you debug it. Can you run it  
in gdb? What happens if you run it like this:
"lli -debug-only=jit hello2.bc".

Also, try -march=arm (if the bitcode file doesn't have the right  
triplet). Also add -mattr=+v6, anything under v6 is not well tested  
(although I am pretty sure v5 works).
