2019-10-14Remove the `Option` in `TokenStream`.Nicholas Nethercote-1/+1
It means an allocation is required to create an empty `TokenStream`, but all other operations are simpler and marginally faster due to not having to check for `None`. Overall it simplifies the code for a negligible performance effect. The commit also removes `TokenStream::empty` by implementing `Default`, which is now possible.

Refactor librustc_errors::Handler API This should be reviewed by-commit. The last commit moves all fields into an inner struct behind a single lock; this is done to prevent possible deadlocks in a multi-threaded compiler, as well as inconsistent state observation.

2019-03-29Use `SmallVec` in `TokenStreamBuilder`.Nicholas Nethercote-1/+2
This reduces by 12% the number of allocations done for a "clean incremental" of `webrender_api`, which reduces the instruction count by about 0.5%. It also reduces instruction counts by up to 1.4% across a range of rustc-perf benchmark runs.

2019-02-18Remove `LazyTokenStream`.Nicholas Nethercote-2/+2
It's present within `Token::Interpolated` as an optimization, so that if a nonterminal is converted to a `TokenStream` multiple times, the first-computed value is saved and reused. But in practice it's not needed. `interpolated_to_tokenstream()` is a cold function: it's only called a few dozen times while compiling rustc itself, and a few hundred times across the entire `rustc-perf` suite. Furthermore, when it is called, it is almost always the first conversion, so no benefit is gained from it. So this commit removes `LazyTokenStream`, along with the now-unnecessary `Token::interpolated()`. As well as a significant simplification, the removal speeds things up slightly, mostly due to not having to `drop` the `LazyTokenStream` instances.

2018-12-12Rename `TokenStream::concat` and remove `TokenStream::concat_rc_vec`.Nicholas Nethercote-1/+1
`TokenStream::new` is a better name for the former, and the latter is now just equivalent to `TokenStream::Stream`.

2017-10-30edit and fix bad spacing of inner-attribute-not-allowed noteZack M. Davis-5/+4
This multiline string literal was missing a backslash, leaving an awkward newline and 35 spaces in the middle of the message. But while we're here, the existing message seems kind of long in comparison to similar notes: to cut it down, we excise the mentions of doc comments, which seems sensible because we know that this erroneous attribute is not a doc comment (notice the `is_sugared_doc: false` at the end of the function; if it had been a doc comment, that error would get set in the `token::DocComment` match branch of `parse_outer_attributes`).

Eat open paren when parsing list in libsyntax/parse/attr.rs This PR adds a small refactoring: ```diff pub fn parse_meta_item_kind(&mut self) -> PResult<'a, ast::MetaItemKind> { Ok(if self.eat(&token::Eq) { ast::MetaItemKind::NameValue(self.parse_unsuffixed_lit()?) - } else if self.token == token::OpenDelim(token::Paren) { + } else if self.eat(&token::OpenDelim(token::Paren)) { ast::MetaItemKind::List(self.parse_meta_seq()?) } else { - self.eat(&token::OpenDelim(token::Paren)); ast::MetaItemKind::Word }) } ``` in `parse_meta_item_kind()`, the parser calls `self.eat(&token::OpenDelim(token::Paren));` before returning `ast::MetaItemKind::Word` just to add `(` to expected token. It seems more natural to eat the paren when parsing `ast::MetaItemKind::List`.
