2019-11-07Rollup merge of #65974 - Centril:matcher-friendly-gating, r=petrochenkovMazdak Farrokhzad-5/+3
A scheme for more macro-matcher friendly pre-expansion gating Pre-expansion gating will now avoid gating macro matchers that did not result in `Success(...)`. That is, the following is now OK despite `box 42` being a valid `expr` and that form being pre-expansion gated: ```rust macro_rules! m { ($e:expr) => { 0 }; // This fails on the input below due to `, foo`. (box $e:expr, foo) => { 1 }; // Successful matcher, we should get `2`. } fn main() { assert_eq!(1, m!(box 42, foo)); } ``` Closes https://github.com/rust-lang/rust/issues/65846. r? @petrochenkov cc @Mark-Simulacrum

2019-11-06Make doc comments cheaper with `AttrKind`.Nicholas Nethercote-5/+7
`AttrKind` is a new type with two variants, `Normal` and `DocComment`. It's a big performance win (over 10% in some cases) because `DocComment` lets doc comments (which are common) be represented very cheaply. `Attribute` gets some new helper methods to ease the transition: - `has_name()`: check if the attribute name matches a single `Symbol`; for `DocComment` variants it succeeds if the symbol is `sym::doc`. - `is_doc_comment()`: check if it has a `DocComment` kind. - `{get,unwrap}_normal_item()`: extract the item from a `Normal` variant; panic otherwise. Fixes #60935.

2019-10-30Reduce ammount of errors given unclosed delimiterEsteban Küber-7/+10
When in a file with a non-terminated item, catch the error and consume the block instead of trying to recover it more granularly in order to reduce the amount of unrelated errors that would be fixed after adding the missing closing brace. Also point out the possible location of the missing closing brace.
2019-10-28Use heuristics to recover parsing of missing `;`Esteban Küber-12/+12
- Detect `,` and `:` typos where `;` was intended. - When the next token could have been the start of a new statement, detect a missing semicolon.

2019-10-02Add support for 'extern const fn'Aaron Hill-19/+33
This works just as you might expect - an 'extern const fn' is a 'const fn' that is callable from foreign code. Currently, panicking is not allowed in consts. When RFC 2345 is stabilized, then panicking in an 'extern const fn' will produce a compile-time error when invoked at compile time, and an abort when invoked at runtime. Since this is extending the language (we're allowing the `const` keyword in a new context), I believe that this will need an FCP. However, it's a very minor change, so I didn't think that filing an RFC was necessary. This will allow libc (and other FFI crates) to make many functions `const`, without having to give up on making them `extern` as well.

2019-09-29Rollup merge of #64894 - Centril:fix-64682, r=petrochenkovMazdak Farrokhzad-26/+18
syntax: fix dropping of attribute on first param of non-method assocated fn Fixes #64682. The general idea is that we bake parsing of `self` into `parse_param_general` and then we just use standard list parsing. Overall, this simplifies the parsing and makes it more consistent. r? @petrochenkov cc @c410-f3r
