OCaml bindings: formatting This commit only changes comments and documentation in OCaml bindings. The official name of the language is OCaml, and the usage is now consistent. Patch by Peter Zotov git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193836 91177308-0d34-0410-b5e6-96231b3b80d8

(*===-- llvm_bitwriter.ml - LLVM OCaml Interface ----------------*- C++ -*-===*
Adding ocaml language bindings for the vmcore and bitwriter libraries. These are built atop the C language bindings, and user programs can link with them as such: # Bytecode ocamlc -cc g++ llvm.cma llvmbitwriter.cma -o example example.ml # Native ocamlopt -cc g++ llvm.cmxa llvmbitwriter.cmxa -o example.opt example.ml The vmcore.ml test exercises most/all of the APIs thus far bound. Unfortunately, they're not yet numerous enough to write hello world.
