2019-07-09Rollup merge of #62520 - pnkfelix:add-test-for-42574, r=alexcrichtonMazdak Farrokhzad-0/+39
Regression test for issue 42574. Cc #42574. I'm not going to say this *closes* that issue yet, for two reasons: 1. I am still confused about some aspects of the behavior we are observing that bug 2. The "fix" to the diagnostic relies on full NLL (`#![feature(nll)]`); migration mode still has a subpar diagnostic.
2019-07-09Rollup merge of #62450 - nagisa:reclimit, r=pnkfelixMazdak Farrokhzad-28/+388
Raise the default recursion limit to 128 The previous limit of 64 is being (just) barely hit by genuine code out there, which is causing issues like https://github.com/rust-lang/rust/issues/62059 to rear their end. Ideally, we wouldn’t have such arbitrary limits at all, but while we do, it makes a lot of sense to just raise this limit whenever genuine use-cases end up hitting it. r? @pnkfelix Fixes https://github.com/rust-lang/rust/issues/62059
2019-07-09Rollup merge of #62417 - alexreg:fix-self-in-type-alias, r=pnkfelixMazdak Farrokhzad-3/+50
Fix ICEs when `Self` is used in type aliases I think it is right just to disallow this at resolution stage rather than let typeck produce a cyclic error. This is in line with previous behaviour. There was probably no need at all for the change that introduced this bug in #57428, so I've simply reversed it. Fixes #62263, #62364, #62305. r? @eddyb
2019-07-09Auto merge of #62233 - matthewjasper:exit-arm-scopes, r=pnkfelixbors-0/+21
Exit arm scopes Due to a bug in the HIR CFG construction, borrows for arm scopes were incorrectly leaking into other arms. This PR also includes some drive-by improvements to `-Zunpretty=hir,identified` that would have been helpful while investigating this. Closes #62107

Use const generics for array impls [part 1] Part 1 of #61415, following the plan in https://github.com/rust-lang/rust/issues/61415#issuecomment-497922482 Found a way that works 🙃

- uses a never-stable core::array::LengthAtMost32 to bound the impls - includes a custom error message to avoid mentioning LengthAtMost32 too often - doesn't use macros for the slice implementations to avoid #62433

2019-07-07Rollup merge of #62213 - QuietMisdreavus:cfg-doctest, r=GuillaumeGomezMazdak Farrokhzad-4/+39
rustdoc: set cfg(doctest) when collecting doctests Note: This PR builds on top of https://github.com/rust-lang/rust/pull/61199; only the last commit is specific to this PR. As discussed in https://github.com/rust-lang/rust/pull/61199, we want the ability to isolate items to only when rustdoc is collecting doctests, but we can't use `cfg(test)` because of libcore's `#![cfg(not(test))]`. This PR proposes a new cfg flag, `cfg(doctest)`, specific to this situation, rather than reusing an existing flag. I've isolated it behind a feature gate so that we can contain the effects to nightly only. (A stable workaround that can be used in lieu of `#[cfg(doctest)]` is `#[cfg(rustdoc)] #[doc(hidden)]`, at least once https://github.com/rust-lang/rust/pull/61351 lands.)

r=petrochenkov name the trait in ambiguous-associated-items fully qualified suggestion We have the trait at this point, so we can name it in the error message, rather than using "Trait" as a (potentially confusing) placeholder. Thanks to Yuki "@JohnTitor" Okushi for pointing out where to look (in the same file) for a closely related issue for ambiguous associated types (as opposed to items; that was #59225, except that one won't be quite as easy to resolve, because we actually don't have the trait `DefId` at that point). r? @petrochenkov

Now that procedural macros no longer link transitively to libsyntax, this shouldn't be needed any more! This commit is an experiment in removing all dynamic libraries from rustc except for librustc_driver itself. Let's see how far we can get with that!

[let_chains, 3/6] And then there was only Loop Here we remove `hir::ExprKind::While`. Instead, we desugar: `'label: while $cond $body` into: ```rust 'label: loop { match DropTemps($cond) { true => $body, _ => break, } } ``` Per https://github.com/rust-lang/rust/issues/53667#issuecomment-471583239. This is a follow up to https://github.com/rust-lang/rust/pull/59288 which did the same for `if` expressions. r? @matthewjasper
