re PR tree-optimization/79725 (Sinking opportunity missed if blocked by dead stmt)
2017-04-24 Richard Biener <rguenther@suse.de>
PR tree-optimization/79725
* tree-ssa-sink.c (statement_sink_location): Return whether
failure reason was zero uses. Move that check later.
(sink_code_in_bb): Deal with zero uses by removing the stmt
if possible.
* gcc.dg/tree-ssa/ssa-sink-15.c: New testcase.
