vrp_prop: Use dom_walker for -Warray-bounds (PR tree-optimization/83312)
gcc/ChangeLog:
PR tree-optimization/83312
* domwalk.h (dom_walker::dom_walker): Fix typo in comment.
* tree-cfg.c (find_taken_edge): Update to handle NULL_TREE for
"val" param, and to cope with arbitrary basic blocks.
(find_taken_edge_cond_expr): Add "cond_stmt" param and use it to
handle NULL_TREE for "val", dropping "bb" param.
(find_taken_edge_switch_expr): Make "switch_stmt" param const and
drop "bb" param. Handle NULL_TREE for "val".
(find_case_label_for_value): Make "switch_stmt" param const.
* tree-vrp.c (class check_array_bounds_dom_walker): New subclass
of dom_walker.
(vrp_prop::check_all_array_refs): Reimplement as...
(check_array_bounds_dom_walker::before_dom_children): ...this new
vfunc. Replace linear search through BB block list, excluding
those with non-executable in-edges via dominator walk.
gcc/testsuite/ChangeLog:
PR tree-optimization/83312
* gcc.dg/pr83312.c: New test case.
