llvm dev - Nov 2012 - [LLVMdev] Emit only one function of the module to native code

Hi

I use llvm-3.1. I have a large module and i want to emit native code (or
assembly) for one function.

I tried to replace the PassManager in llc by a FunctionPassManager but I
have a crash so this is probably not the good way to do it. (cf attached my
simple test)

Is it possible to write one function from the module? What is the good way
to do it?

Thanks in advance.

Christophe

Ok thanks,
I thought there was a more direct way to do it...
