re PR tree-optimization/92751 (VN partial def support confused about clobbers)
2019-12-03 Richard Biener <rguenther@suse.de>
PR tree-optimization/92751
* tree-ssa-sccvn.c (vn_walk_cb_data::push_partial_def): Fail
when a clobber ends up in the partial-def vector.
(vn_reference_lookup_3): Let clobbers be handled by the
assignment from CTOR handling.
* g++.dg/tree-ssa/pr92751.C: New testcase.
