[PR2886] Ignore stderr from ocamlc since it prints unresolvable warnings on some platforms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57976 91177308-0d34-0410-b5e6-96231b3b80d8 2008-10-22 12:41:54 +00:00			`(* RUN: %ocamlc -warn-error A llvm.cma llvm_bitwriter.cma %s -o %t 2> /dev/null`
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 2007-09-18 12:49:39 +00:00			`* RUN: ./%t %t.bc`

Added C and Ocaml bindings for functions, basic blocks, and instruction creation. No support yet for instruction introspection. Also eliminated allocas from the Ocaml bindings for portability, and avoided unnecessary casts. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42367 91177308-0d34-0410-b5e6-96231b3b80d8 2007-09-26 20:56:12 +00:00			`ignore (Llvm.define_type_name "caml_int_ty" Llvm.i32_type m);`
