93e7442f0845e4ee5222a2370eb1a83d513939aa tree-optimization/118717 - store commoning vs. abnormals
When we sink common stores in cselim or the sink pass we have to
make sure to not introduce overlapping lifetimes for abnormals
used in the ref. The easiest is to avoid sinking stmts which
reference abnormals at all which is what the following does.
PR tree-optimization/118717
* tree-ssa-phiopt.cc (cond_if_else_store_replacement_1):
Do not common stores referencing abnormal SSA names.
* tree-ssa-sink.cc (sink_common_stores_to_bb): Likewise.
* gcc.dg/torture/pr118717.c: New testcase.
