[LLVMdev] LLVM languages cooperation

[Sébastien Pierre]

Hi all,

I am an LLVM newbie, thinking about using LLVM as the platform for a toy 
language.

In this respect, I was wondering if LLVM could be used to easily weave 
code written in different language. For instance, let's assume I have a 
library written in C, some components written in C++ and some components 
written in OCaml (we also assume an OCaml backend for LLVM). All this 
code gets compiled to LLVM bytecode.

Is there a way, given this bytecode, to access functions and invoke them 
uniformly ?

This may sound rather fuzzy, but thinking of .NET could help : .NET 
allows to write code in any supported language, the objects and 
functions written in these language become available to all supported 
languages. This is made possible because there is a common object model 
build on top of the .NET VM and bridged to all supported languages. I 
know LLVM does not define an object model, but maybe a common function 
call model ?

TIA,

 -- Sébastien
