2018-12-14Rollup merge of #56699 - nnethercote:SymbolIndex, r=oli-obkkennytm-22/+39
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

2018-12-06Auto 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.

2018-12-01Rollup merge of #56336 - nnethercote:clean-up-pp, r=nikomatsakiskennytm-0/+4
Clean up and streamline the pretty-printer Some minor improvements.
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.
2018-11-27resolve: Implement edition hygiene for imports and absolute pathsVadim Petrochenkov-2/+1
Use per-span hygiene in a few other places in resolve Prefer `rust_2015`/`rust_2018` helpers to comparing editions

2018-04-25Auto merge of #49986 - zofrex:better-derived-argument-names, r=Manishearthbors-0/+4
Provide better names for builtin deriving-generated attributes First attempt at fixing #49967 Not in love with any choices here, don't be shy if you aren't happy with anything :) I've tested that this produces nicer names in documentation, and that it no longer has issues conflicting with constants with the same name. (I guess we _could_ make a test for that... unsure if that would be valuable) In all cases I took the names from the methods as declared in the relevant trait. In some cases I had to prepend the names with _ otherwise there were errors about un-used variables. I'm uneasy with the inconsistency... do they all need to be like that? Is there a way to generate an alternate impl or use a different name (`_`?) in the cases where the arguments are not used? Lastly the gensym addition to Ident I implemented largely as suggested, but I want to point out it's a little circuitous (at least, as far as I understand it). `cx.ident_of(name)` is just `Ident::from_str`, so we create an Ident then another Ident from it. `Ident::with_empty_ctxt(Symbol::gensym(string))` may or may not be equivalent, I don't know if it's important to intern it _then_ gensym it. It seems like either we could use that, or if we do want a new method to make this convenient, it could be on Ident instead (`from_str_gensymed`?)
2018-04-23Use FxHashMap in syntax_pos::symbol::Interner::intern.Nicholas Nethercote-2/+2
Because it's faster than HashMap. This change reduces the time taken for a few of the rustc-perf benchmarks, mostly the small ones, by up to 5%.
2018-04-17Rollup merge of #49699 - zesterer:master, r=joshtriplettGuillaume Gomez-14/+13
Removed 'proc' from the reserved keywords list Remove 'proc' from the reserved keywords list. 'proc' is a very useful identifier name for a lot of things. It's especially useful when dealing with processes, operating system internals, and kernel development.
