From cbf8434e44ebd6bc05022d1fbe0400267520184f Mon Sep 17 00:00:00 2001
From: Xavier Leroy <xavier.leroy@inria.fr>
Date: Fri, 20 Mar 2015 11:25:30 +0100
Subject: Improvements in the StructReturn transformation (ABI conformance for
 passing composites).

- Implement the "1/2/4/8" composite return policy, used by IA32/MacOS X and IA32/BSD.
- Move the default passing conventions from Machine.ml to compcert.ini, making it easier to test the various conventions.
- More comprehensive interoperability test in regression/interop1.c.
