        * tree-ssa-dse.c (delete_dead_or_redundant_assignment): New param
        need_eh_cleanup with default value NULL. Gate on need_eh_cleanup
        before calling bitmap_set_bit.
        (dse_optimize_redundant_stores): Pass global need_eh_cleanup to
        delete_dead_or_redundant_assignment.
        (dse_dom_walker::dse_optimize_stmt): Likewise.
        * tree-ssa-dse.h (delete_dead_or_redundant_assignment): Adjust
prototype.

testsuite/
        * gcc.dg/tree-ssa/pr92163.c: New test.
