bors 36ecbc94eb Auto merge of #80632 - Nadrieril:fix-80501, r=varkor ... Identify unreachable subpatterns more reliably In https://github.com/rust-lang/rust/pull/80104 I used `Span`s to identify unreachable sub-patterns in the presence of or-patterns during exhaustiveness checking. In https://github.com/rust-lang/rust/issues/80501 it was revealed that `Span`s are complicated and that this was not a good idea. Instead, this PR identifies subpatterns logically: as a path in the tree of subpatterns of a given pattern. I made a struct that captures a set of such subpatterns. This is a bit complex, but thankfully self-contained; the rest of the code does not need to know anything about it. Fixes https://github.com/rust-lang/rust/issues/80501. I think I managed to keep the perf neutral. r? `@varkor`		2021-02-07 16:48:57 +00:00
