cherry-pick over the tests I wrote for the reachability code For the most part, the current code performs similarly, although it differs in some particulars. I'll be nice to have these tests for judging future changes, as well. 2017-03-21 13:41:41 +00:00			`#![allow(unused_variables)]`

Don't abort compilation after giving a lint error The only reason to use `abort_if_errors` is when the program is so broken that either: 1. later passes get confused and ICE 2. any diagnostics from later passes would be noise This is never the case for lints, because the compiler has to be able to deal with `allow`-ed lints. So it can continue to lint and compile even if there are lint errors. 2021-07-21 03:23:22 +00:00			`//~\| ERROR non-primitive cast`
