re PR tree-optimization/71261 (Trunk GCC hangs on knl and broadwell targets)
2016-05-25 Richard Biener <rguenther@suse.de>
PR tree-optimization/71261
* tree-if-conv.c (ifcvt_split_def_stmt): Walk uses on the
interesting stmt instead of immediate uses when looking
for the use operand to replace.
* c-c++-common/torture/pr71261.c: New testcase.
