I would prefer not to write the front end in c or c++ though if it can be avoided.  I read online that the ocaml bindings are distributed with llvm but are not always as up to date as the c or c++ bindings.  Is this (still) the case?  Is there anything that the c/c++ bindings can do that the ocaml ones cannot?

The C++ objects (values, instructions, modules, ...) are opaque in
OCaml. To program them, we need to use the wrapped C++ interfaces for
these objects if there were, and we cannot  'pattern-match' these
objects. For example, the current OCaml bindings can let us build a
LLVM IR (the high-level source language can be translated into LLVM IR
with these interfaces), call any existing analysis or transformations.
To design a new pass in OCaml, it might need to expose more C++
primitives, so it is more convenient to program in C++ once we can
build IR from the source language with OCaml bindings. But I don't
know if there is an better way to expose C++ to OCaml.
