2019-10-14Rollup merge of #65415 - petrochenkov:rmtest, r=varkorTyler Mandry-16/+0
Remove an outdated test output file It was accidentally introduced during some rebase, but it's no longer necessary and `--bless` removes it, but it doesn't fail testing.
2019-10-14Rollup merge of #65410 - Centril:intersection-pat-recover, r=davidtwco,varkorTyler Mandry-0/+73
syntax: add parser recovery for intersection- / and-patterns `p1 @ p2` Fixes https://github.com/rust-lang/rust/issues/65400. The recovery comes in two flavors: 1. We know that `p2` is a binding so we can invert as `p2 @ p1`: ```rust error: pattern on wrong side of `@` --> $DIR/intersection-patterns.rs:13:9 | LL | Some(x) @ y => {} | -------^^^- | | | | | binding on the right, should be to the left | pattern on the left, should be to the right | help: switch the order: `y @ Some(x)` ``` 2. Otherwise we emit a generic diagnostic for the lack of support for intersection patterns: ```rust error: left-hand side of `@` must be a binding --> $DIR/intersection-patterns.rs:23:9 | LL | Some(x) @ Some(y) => {} | -------^^^------- | | | | | also a pattern | interpreted as a pattern, not a binding | = note: bindings are `x`, `mut x`, `ref x`, and `ref mut x` ``` For more on and-patterns, see e.g. https://docs.microsoft.com/en-us/dotnet/fsharp/language-reference/pattern-matching#and-pattern. r? @davidtwco cc @varkor @lzutao

2019-10-13Rollup merge of #65346 - RalfJung:nounwind-tests, r=nagisaMazdak Farrokhzad-25/+60
nounwind tests and cleanup This is a follow-up to @pnkfelix' https://github.com/rust-lang/rust/pull/65020. In particular it adds some tests as @nagisa asked. It also does a cleanup that the original PR omitted to reduce backporting risks. I hope I finally managed to write an uncontroversial PR in this area. ;) This should not change any behavior, just test it better.
2019-10-13Rollup merge of #65214 - Amanieu:cfg_atomic, r=alexcrichtonMazdak Farrokhzad-1/+1
Split non-CAS atomic support off into target_has_atomic_load_store This PR implements my proposed changes in https://github.com/rust-lang/rust/issues/32976#issuecomment-518542029 by removing `target_has_atomic = "cas"` and splitting `target_has_atomic` into two separate `cfg`s: * `target_has_atomic = 8/16/32/64/128`: This indicates the largest width that the target can atomically CAS (which implies support for all atomic operations). * ` target_has_atomic_load_store = 8/16/32/64/128`: This indicates the largest width that the target can support loading or storing atomically (but may not support CAS). cc #32976 r? @alexcrichton

pnkfelix:targetted-fix-for-always-marking-rust-abi-unwind-issue-64655, r=alexcrichton Always mark rust and rust-call abi's as unwind PR #63909 identified a bug that had been injected by PR #55982. As discussed on https://github.com/rust-lang/rust/issues/64655#issuecomment-537517428 , we started marking extern items as nounwind, *even* extern items that said they were using "Rust" or "rust-call" ABI. This is a more targeted variant of PR #63909 that fixes the above bug. Fix #64655 ---- I personally suspect we will want PR #63909 to land in the long-term But: * it is not certain that PR #63909 *will* land, * more importantly, PR #63909 almost certainly will not be backported to beta/stable. The identified bug was more severe than I think anyone realized (apart from perhaps @gnzlbg, as noted [here](https://github.com/rust-lang/rust/pull/63909#issuecomment-524818838)). Thus, I was motivated to write this PR, which fixes *just* the issue with extern rust/rust-call functions, and deliberately avoids injecting further deviation from current behavior (you can see further notes on this in the comments of the code added here).
2019-10-11Rollup merge of #65321 - Mark-Simulacrum:remove-linker-no-utf8-test, ↵Tyler Mandry-39/+0
r=nikomatsakis Remove painful test that is not pulling its weight Research suggests that we are not properly testing this case anyway, and even if we were, it is unlikely that we will regress here -- or, perhaps more accurately, if we do, I am uncertain that we care too much. It definitely seems like an edge case, and one that is particularly unlikely to occur as time goes on. Fixes https://github.com/rust-lang/rust/issues/63520
2019-10-11Rollup merge of #65310 - da-x:issue-56195, r=petrochenkovTyler Mandry-0/+6
deriving: avoid dummy Span on an artificial `type_ident` path The dummy Span pointed to the beginning of the source file instead to where the `#[derive]` is located. Later, it tripped the `in_derive_expansion(span)` check at `src/librustc/middle/stability.rs`, causing a span-less deprecation warning to be emitted. Fixes #56195, Fixes #55417.
