re PR tree-optimization/70372 (ICE: in wide_int_to_tree, at tree.c:1488 with -fno-tree-fre and v2ti vectors)
2016-03-24 Richard Biener <rguenther@suse.de>
PR tree-optimization/70372
* tree-ssa-reassoc.c (eliminate_plus_minus_pair): Use
build_all_ones_cst to also handle vector types correctly.
* gcc.dg/tree-ssa/pr70372.c: New testcase.
