[llvm-dev] How to pass arbitrary arguments to runFunctionAsMain?

[Alberto Barbaro via llvm-dev]

Hi Tim,
Thanks for your answer. I'll fix the problem with envp now.

I don't know if you have seen my other question but i was doubting of that
code because I cannot get the proper value of argv at runtime using my
Interpreter. I hope this is the problem. Do you think the same?

Thanks again
