Assembly code from Ocaml

I have simple ocaml file test.ml

1 + 2;;

I compiled it. can i see assem开发者_如何转开发bly output of this code? Maybe ocaml packet has any tools for this?

Thank you.

Yes you can: see below. Everything that remains from your code is movl $7, %eax (7 is OCaml's representation for 3, which is the result of 1+2).

$ cat > t.ml
1 + 2 ;;
$ ocamlopt -S t.ml
$ cat t.s
