For those who don't realise how exciting this could be:
LLVM has since spawned a wide variety of front ends: languages with compilers that use LLVM include Common Lisp, ActionScript, Ada, D, Fortran, OpenGL Shading Language, Go, Haskell, Java bytecode, Julia, Objective-C, Swift, Python, Ruby, Rust, Scala, and Lua.
Is the source available SainT? I can't promise anything, but I can take a look. Lots of C/68k experience here, but no LLVM I'm afraid.
