Hi,

have you seen that the go bindings already contain a C wrapper for the
DIBuilder class?

https://github.com/llvm-mirror/llvm/blob/master/bindings/go/llvm/DIBuilderBindings.h

It contains this comment:

// FIXME: These bindings shouldn't be Go-specific and should eventually
// move to a (somewhat) less stable collection of C APIs for use in
// creating bindings of LLVM in other languages.

I would also be interested in OCaml bindings for this.

Best,
Ulrich

Exposing DIBuilder to llvm-c properly is somewhat complicated and what
you propose was considered and rejected over two years ago. However,
there is ongoing work to bring debug information to LLVM-C and you
may watch it on http://reviews.llvm.org/D19088.

After that's merged the OCaml part is straightforward.
