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. But: $ cat example.ml (* example.ml *) open Llvm open Llvm_bitwriter let _ = let filename = Sys.argv.(1) in let m = create_module filename in let v = make_int_constant i32_type 42 false in let g = define_global "hello_world" v m in if not (write_bitcode_file m filename) then exit 1; dispose_module m; $ ocamlc -cc g++ llvm.cma llvm_bitwriter.cma -o example example.ml File "example.ml", line 11, characters 6-7: Warning Y: unused variable g. $ ./example example.bc $ llvm-dis < example.bc ; ModuleID = '<stdin>' @hello_world = global i32 42 ; <i32*> [#uses=0] The ocaml test cases provide effective tests for the C interfaces. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42093 91177308-0d34-0410-b5e6-96231b3b80d8
