From 86c5e03fd7a31965c1518ea5492c7feab469bea5 Mon Sep 17 00:00:00 2001
From: Erwan Jahier <jahier@imag.fr>
Date: Wed, 18 Jun 2008 17:49:15 +0200
Subject: [PATCH] Add a New module that checks that all variables (outputs and
locals) are defined exactly once.
This algo is naive and does not work with slices of slices with
negative steps. I commit it before trying a new one to get better
non-reg test.
Fix some non-reg test in the should_work dir that this new check revealed.
