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

2018-12-10Update 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

2018-09-09Auto merge of #53778 - petrochenkov:shadrelax2, r=nikomatsakisbors-0/+5
resolve: Relax shadowing restrictions on macro-expanded macros Previously any macro-expanded macros weren't allowed to shadow macros from outer scopes. Now only "more macro-expanded" macros cannot shadow "less macro-expanded" macros. See comments to `fn may_appear_after` and added tests for more details and examples. The functional changes are a21f6f588fc28c97533130ae44a6957b579ab58c and 46dd365ce9ca0a6b8653849b80267763c542842a, other commits are refactorings.
