re PR tree-optimization/35472 (tree DSE is broken)
2008-03-05 Richard Guenther <rguenther@suse.de>
PR tree-optimization/35472
* tree-ssa-dse.c (dse_optimize_stmt): Do not delete a store
whose single use_stmt has a overlapping set of loaded and
stored symbols as that use_stmt might be a noop assignment then.
* gcc.c-torture/execute/pr35472.c: New testcase.
