[LLVMdev] problems with llvmgcc

[Xiaodong Li]

Dear Prof. Adve,

Now I can use llvmgcc to compile a .c file into .bc file. But I still have
trouble simply run the .bc code. Below is the sequence I got when I tried.
I really don't know what's going on here. Please let me know how can I fix
it.

Thanks,
xiaodong
