re PR tree-optimization/63168 (loop header copying fails - not vectorized: latch block not empty)
2014-10-16 Richard Biener <rguenther@suse.de>
PR tree-optimization/63168
* tree-cfg.c (gimple_can_merge_blocks_p): Only protect
latches if after merging they are no longer simple.
* cfghooks.c (merge_blocks): Handle merging a latch block
into another block.
* gcc.dg/tree-ssa/loop-40.c: New testcase.
