Hello, I'm trying to use Llvm_bitwriter + ocamlbuild, but it doesn't recognize its dependency on Unix, so it doesn't compile. Minimal case: (* FILE: minimal.ml *) let main () = let m = Llvm.create_module (Llvm.global_context ()) "test" in ignore (Llvm_bitwriter.output_bitcode stdout m) ;; main () (* FILE: _t...

Hi, where can I read more about this? I assume (hope) the lib provides some kind of OCaml bindings? I could not find any trace of it in the 2.1 release source so I guess it's currently SVN only? greetings, Jan On 2.

There is one thing I probably won't get around to doing myself until after the code freeze. (* Llvm_bitwriter *) val output_bitcode: out_channel -> Llvm.llmodule -> unit It would, of course, be awesome if you could get that into the 2.7 train. — j h woodyatt <jhw at conjury.org> http://jhw.vox.com/

I've pretty much finished exposing all I wanted to llvm-c and the ocaml bindings for the soon to be released 2.7. Does anyone need any other functions exposed before the code freeze on the 7th?

...jority of the bindings, so they deserve most of the praise. I believe there are techniques for walking over the CFG. You can load up code using Llvm_bitreader, use things like Llvm.iter_globals, Llvm.iter_functions, and Llvm.iter_instrs to walk over the module, and write out a new llmodule using Llvm_bitwriter. Is there something more specific you want to do?

Hi! I just took another look at the LLVM project and it has come along in leaps and bounds since I last looked. I've been working through the (awesome!) tutorial and am now really hyped about the project. I am particularly interested in using LLVM to write compilers for OCaml-like languages in OCaml-like languages. This requires some core functionality that would be generically useful:

Right. I hadn't noticed they were already installed after llvm "make install" in:...
