2019-02-12Auto merge of #58341 - alexreg:cosmetic-2-doc-comments, r=steveklabnikbors-31/+31
Cosmetic improvements to doc comments This has been factored out from https://github.com/rust-lang/rust/pull/58036 to only include changes to documentation comments (throughout the rustc codebase). r? @steveklabnik Once you're happy with this, maybe we could get it through with r=1, so it doesn't constantly get invalidated? (I'm not sure this will be an issue, but just in case...) Anyway, thanks for your advice so far!
2019-02-12Auto merge of #58098 - oli-obk:maybe_allow_internal_unstable, r=petrochenkovbors-5/+10
Require a list of features in `#[allow_internal_unstable]` The blanket-permission slip is not great and will likely give us trouble some point down the road.

feature list while we could make this change (it's all unstable after all), there are crates.io crates that use the feature and that the compiler depends upon. We can instead roll out this feature while still supporting the old way.

2019-01-20Use is_dummy instead of comparing against DUMMY_SPEsteban Küber-2/+2
2019-01-20Remove unnecessary dummy span checksEsteban Küber-0/+10
The emitter already verifies wether a given span note or span label can be emitted to the output. If it can't, because it is a dummy span, it will be either elided for labels or emitted as an unspanned note/help when applicable.

2018-12-14Rollup merge of #56699 - nnethercote:SymbolIndex, r=oli-obkkennytm-22/+42
Use a `newtype_index!` within `Symbol`. This shrinks `Option<Symbol>` from 8 bytes to 4 bytes, which shrinks `Token` from 24 bytes to 16 bytes. This reduces instruction counts by up to 1% across a range of benchmarks. r? @oli-obk
2018-12-12Bump to 1.33.0Alex Crichton-1/+1
* Update bootstrap compiler * Update version to 1.33.0 * Remove some `#[cfg(stage0)]` annotations Actually updating the version number is blocked on updating Cargo
2018-12-12Use a `newtype_index!` within `Symbol`.Nicholas Nethercote-22/+42
This shrinks `Option<Symbol>` from 8 bytes to 4 bytes, which shrinks `Token` from 24 bytes to 16 bytes. This reduces instruction counts by up to 1% across a range of benchmarks.
2018-12-10Update Cargo submodule and its dependenciesAlex Crichton-2/+1
Hopefully just another routine update! So far this starts to enable the `std::arch` in stage0 builds of rustc. This means that we may need stage0/not(stage0) in stdsimd itself, but more and more code is starting to use `std::arch` so I think it's time to start shifting the balance of work here.

2018-12-06Auto merge of #56392 - petrochenkov:regensym, r=oli-obkbors-1/+5
Delay gensym creation for "underscore items" (`use foo as _`/`const _`) until name resolution So they cannot be cloned by macros. See https://github.com/rust-lang/rust/pull/56303 for the discussion. Mostly fix cross-crate use of underscore items by inverting the "gensyms are lost in metadata" bug as described in https://github.com/rust-lang/rust/pull/56303#issuecomment-442464695. Fix unused import warnings for single-segment imports (first commit) and `use crate_name as _` imports (as specified in https://github.com/rust-lang/rust/pull/56303#issuecomment-442274118). Prohibit accidentally implemented `static _: TYPE = EXPR;` (cc https://github.com/rust-lang/rust/pull/55983). Add more tests for `use foo as _` imports.

2018-11-29Use `Cow` in `Token::String`.Nicholas Nethercote-0/+4
`Printer::word` takes a `&str` and converts it into a `String`, which causes an allocation. But that allocation is rarely necessary, because `&str` is almost always a `&'static str` or a `String` that won't be used again. This commit changes `Token::String` so it holds a `Cow<'static, str>` instead of a `String`, which avoids a lot of allocations.

2018-09-28Auto merge of #54338 - orium:fix-macro-inc-comp, r=nrcbors-1/+1
Use full name to identify a macro in a `FileName`. 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. r? @nrc
