Subject: S/390: Require a hardware vector support for test to succeed.
X-Git-Tag: upstream/12.2.0~49099
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a1c9546419aae2a19c525eef66a6660826389305;p=platform%2Fupstream%2Fgcc.git

S/390: Require a hardware vector support for test to succeed.

The test case works on S/390 too, but only with -march=z13 or later
(i.e. if Gcc can make use of hardware vector support).  Otherwise the
optimization gets too complex.  The attached patch forces Gcc to use
-march=z13 instead of xfail'ing the test on S/390.

	test to succeed.
