Original bug ID: 3206
Reporter: administrator
Status: closed (set by @mshinwell on 2016-12-06T21:11:54Z)
Resolution: not a bug
Priority: normal
Severity: feature
Category: ~DO NOT USE (was: OCaml general)

Bug description

Full_Name: David Monniaux
Version: 3.09+dev0
OS: Linux/AMD64
Submission from: massena-8-82-225-77-14.fbx.proxad.net (82.225.77.14)

let foo2 hl hr =
match ( >= ) hl (hr + 2) with
| true -> print_endline "miaou2"
| false -> print_endline "coincoin2";;

generates slightly less good code than:

let foo1 hl hr =
if hl >= hr + 2
then
print_endline "miaou1"
else
print_endline "coincoin1";;

(This is for Coq extractions.)

Flambda is about to make the code generation for this identical (if it isn't already) and I don't think we need to keep this issue open to track that.
