Subject: [committed] Fix PR target/56214
Date: Mon, 18 Feb 2013 05:38:44 -0000
From: John David Anglin <dave@hiauly1.hia.nrc.ca>

To: gcc-patches@gcc.gnu.org

The attached change fixes PR target/56214.  We need to reject everything
but QImode and HImode when reload is in progress and strict is specified.

Tested on hppa2.0w-hp-hpux11.11 and hppa64-hp-hpux11.11.  Committed to
trunk.

Dave
