Subject: Patch to fix vector tests on IA64 HP-UX
Date: Fri, 01 Jun 2007 20:27:00 -0000	[thread overview]
Message-ID: <200706012027.NAA21688@hpsje.cup.hp.com> (raw)

A number of vect tests are failing on IA64 HP-UX because we are swapping
vector elements when we shouldn't be.  This patch removes the BIG_ENDIAN
test and does the same thing for both big and little endian platforms.

Tested on IA64 HP-UX and Linux, it caused no regressions on Linux and
on HP-UX it fixes:

	FAIL: gcc.dg/vect/no-tree-dom-vect-bug.c execution test
	FAIL: gcc.dg/vect/pr30784.c execution test
	FAIL: gcc.dg/vect/vect-14.c execution test
	FAIL: gcc.dg/vect/vect-14.c execution test
	FAIL: gcc.dg/vect/vect-iv-10.c execution test
	FAIL: gcc.dg/vect/vect-iv-10.c execution test
	FAIL: gcc.dg/vect/vect-iv-2.c execution test
	FAIL: gcc.dg/vect/vect-iv-2.c execution test
	FAIL: gcc.dg/vect/vect-iv-3.c execution test
	FAIL: gcc.dg/vect/vect-iv-3.c execution test

OK to checkin?  Maybe it is obvious.
