Subject: Obvious patch for IA64 cleanup
Date: Tue, 31 Jul 2007 20:32:00 -0000 [thread overview]
Message-ID: <200707311846.LAA29748@hpsje.cup.hp.com> (raw)
I will check in this small cleanup patch under the obvious rule if no
one complains. I visually checked that the U constraint was only used
in vector contexts and I also did a bootstrap and test of IA64 HP-UX and
Linux with no regressions.
