Point at enum definition when match patterns are not exhaustive ``` error[E0004]: non-exhaustive patterns: type `X` is non-empty --> file.rs:9:11 | 1 | / enum X { 2 | | A, | | - variant not covered 3 | | B, | | - variant not covered 4 | | C, | | - variant not covered 5 | | } | |_- `X` defined here ... 9 | match x { | ^ | = help: ensure that all possible cases are being handled, possibly by adding wildcards or more match arms error[E0004]: non-exhaustive patterns: `B` and `C` not covered --> file.rs:11:11 | 1 | / enum X { 2 | | A, 3 | | B, 4 | | C, | | - not covered 5 | | } | |_- `X` defined here ... 11 | match x { | ^ patterns `C` not covered ``` When a match expression doesn't have patterns covering every variant, point at the enum's definition span. On a best effort basis, point at the variant(s) that are missing. This does not handle the case when the missing pattern is due to a field's enum variants: ``` enum E1 { A, B, C, } enum E2 { A(E1), B, } fn foo() { match E2::A(E1::A) { E2::A(E1::B) => {} E2::B => {} } //~^ ERROR `E2::A(E1::A)` and `E2::A(E1::C)` not handled } ``` Unify look between match with no arms and match with some missing patterns. Fix #37518.

2019-03-03Auto merge of #58505 - schomatis:fix/nll/remove-live-var, r=matthewjasperbors-267/+179
[NLL] Remove `LiveVar` The `LiveVar` type (and related) made it harder to reason about the code. It seemed as an abstraction that didn't bring any useful concept to the reader (when transitioning from the RFC theory to the actual implementation code). It achieved a compactness in the vectors storing the def/use/drop information that was related only to the `LocalUseMap`. This PR went in the other direction and favored time over memory (but this decision can be easily reverted to the other side without reintroducing `LiveVar`). What this PR aims at is to clarify that there's no significant transformation between the MIR `Local` and the `LiveVar` (now refactored as `live_locals: Vec<Local>`): we're just filtering (not mapping) the entire group of `Local`s into a meaningful subset that we should perform the liveness analysis on. As a side note, there is no guarantee that the liveness analysis is performed only on (what the code calls) "live" variables, if the NLL facts are requested it will be performed on *any* variable so there can't be any assumptions on that regard. (Still, this PR didn't change the general naming convention to reduce the number of changes here and streamline the review process). **Acceptance criteria:** This PR attempts to do only a minor refactoring and not to change the logic so it can't have any performance impact, particularly, it can't lose any of the significant performance improvement achieved in the great work done in https://github.com/rust-lang/rust/pull/52115. r? @nikomatsakis

2019-03-03race condition in thread local storage examplebenaryorg-1/+4
The example had a potential race condition that would still pass the test. If the thread which was supposed to modify it's own thread local was slower than the instruction to modify in the main thread, then the test would pass even in case of a failure. This is would be minor if the child thread was waited for since it check using an `assert_eq` for the same thing, but vice versa. However, if the `assert_eq` failed this would trigger a panic, which is not at all caught by the example since the thread is not waited on. Signed-off-by: benaryorg <binary@benary.org>

2019-03-03Auto merge of #58464 - jethrogb:jb/std-test-panic-output, r=alexcrichtonbors-19/+41
Use the correct stderr when testing libstd When compiling the unit tests for libstd, there are two copies of `std` in existence, see [lib.rs](https://github.com/rust-lang/rust/blob/919cf42/src/libstd/lib.rs#L335-L341). This means there are two copies of everything, including thread local variable definitions. Before this PR, it's possible that libtest would configure a stderr sink in one of those copies, whereas the panic logic would inspect the sink in the other copy, resulting in libtest missing the relevant panic message. This PR makes sure that when testing, the panic logic always accesses the stderr sink from “realstd”, using the same logic that libtest uses.
