llvm dev - Mar 2007 - [LLVMdev] Address of an instruction (or a label?)

Hi everyone,

I'm developing a Java compiler with llvm and I would like to implement 
the (bytecode instruction <--> source line in Java code) feature. This 
requires to get the address of a generated instruction.

Is there a way in llvm to get the address of a generated instruction? Or 
somehow to fix the location of a label in the llvm code (something that 
may look like a basic block perhaps) and get after the compilation the 
address of this label?

Thx,
Nicolas
