From 5ce14085379d6170b466d82db34e8fc4fcc00b7f Mon Sep 17 00:00:00 2001
From: Brian Gaeke <gaeke@uiuc.edu>
Date: Fri, 16 Jul 2004 10:31:25 +0000
Subject: Do IMPLICIT_DEFs on incoming args' hard regs, to avoid confusing the
 regalloc. Support single-fp incoming args. Support single-fp outgoing args
 ('call' operands). Support double-fp return values.
