/me squints -- either we added the coverage to the wrong file, or something else weird has gone wrong. Either way, in 5ce2f73b2e5e I've added another `--try-experimental-debuginfo-iterators` runline to ``CodeGen/AArch64/stack-tagging-dbg.ll, which does in fact fail if you delete the relevant lines. Apologies for the intervening bother.
