2018-10-03Auto merge of #54358 - flip1995:beta, r=Manishearthbors-1/+1
[beta] Cancel warning for tool_lints For the discussion about this, see: rust-lang-nursery/rust-clippy#3159 `clippy-preview` is available on stable since 1.29. So when running `cargo +beta clippy` on a crate with `#![allow(clippy_lint)]` a warning is produced, which tells the programmer to change this to `#![allow(clippy::clippy_lint)]`. But since `tool_lints` aren't stable yet, this would require a `#![feature(tool_lints)]`. Features aren't available on stable or beta, so we cannot do this. Even wrapping `cfg_attr(clippy)` around this won't help, since Clippy can also be run from stable or beta toolchain. r? @Manishearth
2018-10-02Use full name to identify a macro in a `FileName`.Diogo Sousa-0/+26
Before this two macros with same name would be indistinguishable inside a `FileName`. This caused a bug in incremental compilation (see #53097) since two different macros would map out to the same `StableFilemapId`. Fixes #53097.

Make rustc::middle::region::Scope's fields public This PR makes the following changes to `rustc::middle::region::Scope`: - [x] Makes `region::Scope`'s fields public - [x] Removes the `impl Scope` block with constructors (as per [this comment](https://github.com/rust-lang/rust/pull/54032#discussion_r216618208)) - [x] Updates call sites throughout the compiler Closes #54122.

2018-09-15Auto merge of #54151 - ljedrz:cleanup_hir, r=michaelwoeristerbors-155/+93
A few cleanups for hir - prefer `if let` to `match` when only 1 branch matters - `chain` iterable items that are looped over in sequence - `sort_by_key` instead of `sort_by` when possible - change cloning `map`s to `cloned()` - use `unwrap_or_else` and `ok` when applicable - a few other minor readability improvements - whitespace fixes

2018-09-14Rollup merge of #54173 - phansch:suggest_valid_crate_type, r=estebankkennytm-0/+9
Suggest valid crate type if invalid crate type is found This adds a suggestion to the `invalid_crate_types` lint. The suggestion is based on the Levenshtein distance to existing crate types. If no suggestion is found it will show the lint without any suggestions. Closes #53958
2018-09-14Rollup merge of #54095 - kenta7777:kenta7777#53719, r=davidtwcokennytm-8/+8

2018-09-14Rollup merge of #53950 - michaelwoerister:more-lto-cli, r=alexcrichtonkennytm-20/+65
Allow for opting out of ThinLTO and clean up LTO related cli flag handling. It turns out that there currently is no way to explicitly disable ThinLTO (except for the nightly-only `-Zthinlto` flag). This PR extends `-C lto` to take `yes` and `no` in addition to `thin` and `fat`. It should be backwards compatible. It also cleans up how LTO mode selection is handled. Note that merging the PR in the current state would make the new values for `-C lto` available on the stable channel. I think that would be fine but maybe some team should vote on it.

2018-09-12Rollup merge of #54106 - flip1995:pub_checklintnameresult, r=Manishearthkennytm-1/+1
Reexport CheckLintNameResult Make the enum `CheckLintNameResult` public, so that lint tools (aka Clippy) can use it together with [`LintStore::check_lint_name`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc/lint/struct.LintStore.html#method.check_lint_name), to handle the case that a scoped `tool_lint` doesn't exist in the tool. This is currently not handled by the compiler: https://github.com/rust-lang/rust/blob/595345419d12c3ea860151df52f78744a31bafff/src/librustc/lint/levels.rs#L309-L314 Needed for rust-lang-nursery/rust-clippy#3161 r? @Manishearth

nikomatsakis:nll-universe-subtyping-and-pattern-ascription, r=pnkfelix support ascription for patterns in NLL This implements the strategy outlined in [this comment](https://github.com/rust-lang/rust/issues/47184#issuecomment-416669986): - We first extend the NLL subtyping code so it can handle inference variables and subtyping. - Then we extend HAIR patterns with type ascription. - Then we treat the type `T` in `let pat: T = ...` as an ascription. Before landing, a few things: - [x] Fix the WF rule bug (filed a FIXME https://github.com/rust-lang/rust/issues/54105) - [x] Fix an ICE I encountered locally around bound regions, or else file a follow-up - [x] More tests probably =) r? @pnkfelix
