llvm dev - Apr 2010 - [LLVMdev] Parsing (and compiling) on demand.

Hi!

I'm trying to develop JIT compiler using LLVM as its backend. I know
LLVM itself supports JIT-compiling, but I need to generate IR first.
I don't want to generate IR before function is actually needed. How
can I achieve this?
If it matters, I have prototypes for all functions I'm going to use.

Best regards,
Milovanov Victor.

Ok than, but how to insert a call to an undefined function?
