[PATCH] D89959: UBSAN: emit distinctive traps in trapping mode

[Tim Northover via Phabricator via llvm-commits]

t.p.northover updated this revision to Diff 302267.
t.p.northover marked 3 inline comments as done.
t.p.northover added a comment.

Thanks. This switches to i8 argument so there's no possibility of ignoring bits and merges the debug info as suggested.
