re PR tree-optimization/44861 (internal compiler error: in vectorizable_load, at tree-vect-stmts.c:3812)
2010-07-08 Richard Guenther <rguenther@suse.de>
PR tree-optimization/44861
* tree-vect-stmts.c (vectorizable_store): Preserve TBAA
information when building MEM_REFs.
(vectorizable_load): Likewise.
* tree-vect-data-refs.c (vect_setup_realignment): Likewise.
* g++.dg/vect/pr44861.cc: New testcase.
