re PR middle-end/60482 (Loop optimization regression)
PR middle-end/60482
* tree-vrp.c (register_edge_assert_for_1): Don't add assert
if there are multiple uses, but op doesn't live on E edge.
* tree-cfg.c (assert_unreachable_fallthru_edge_p): Also ignore
clobber stmts before __builtin_unreachable.
* gcc.dg/vect/pr60482.c: New test.
