[llvm-dev] Generating completely position agnostic code

[Hayden Livingston via llvm-dev]

Because I don't think it is required. All I want to do is generate
machine code for a single function that has all its references coming
in as pointers on the stack and it's just calling functions and doing
math. I'm literally asking LLVM convert text in the form of C to x86
ASM.

Maybe I'll paste LLVM IR to make it clear what I'm asking for.
