PR testsuite/44325 is about the gcc.dg/vect/vect-109.c FAIL on numerous targets since the PR44284 fix in late May. This test case now also fails with 4.5 on those targets since the PR44284 backport a few days ago. Recently the test case was fixed on trunk as part of r161797, a vectorizer realignment improvement patch. This patch backports just the vect-109.c fix, which suffices to prevent the regression. Tested on {powerpc64,sparc64}-linux where it eliminated the new FAIL, and on i686-linux where it caused no change (since i686 is a vect_hw_misalign target). Ok for 4.5? (I don't have svn write access.) gcc/testsuite/ 2010-07-10 Mikael Pettersson <mikpe@it.uu.se> PR testsuite/44325 Backport from mainline 2010-07-04 Ira Rosen <irar@il.ibm.com> Revital Eres <eres@il.ibm.com> * gcc.dg/vect/vect-109.c: Expect vectorization only on targets that support misaligned stores.
