Subject: [committed] Fix PR target/44705: Invalid MEM with LABEL_REF

To: gcc-patches@gcc.gnu.org

The enclosed change fixes PR target/44705.  This regression was exposed
by the new testcase gcc.dg/pr44674.c.  It's a bit surprising that this
was never reported before since the mistake in GO_IF_LEGITIMATE_ADDRESS
has been around for some time.

Tested on hppa2.0w-hp-hpux11.11, hppa64-hp-hpux11.11, hppa-unknown-linux-gnu.
The hpux tests were done on trunk, 4.5 and 4.3.  Committed to trunk, 4.5,
4.4 and 4.3.

Dave
