2020-02-18Rollup merge of #69194 - Centril:assoc-extern-fuse, r=petrochenkovMazdak Farrokhzad-2/+2
parse: fuse associated and extern items up to defaultness Language changes: - The grammar of extern `type` aliases is unified with associated ones, and becomes: ```rust TypeItem = "type" ident generics {":" bounds}? where_clause {"=" type}? ";" ; ``` Semantic restrictions (`ast_validation`) are added to forbid any parameters in `generics`, any bounds in `bounds`, and any predicates in `where_clause`, as well as the presence of a type expression (`= u8`). (Work still remains to fuse this with free `type` aliases, but this can be done later.) - The grammar of constants and static items (free, associated, and extern) now permits the absence of an expression, and becomes: ```rust GlobalItem = {"const" {ident | "_"} | "static" "mut"? ident} {"=" expr}? ";" ; ``` - A semantic restriction is added to enforce the presence of the expression (the body). - A semantic restriction is added to reject `const _` in associated contexts. Together, these changes allow us to fuse the grammar of associated items and extern items up to `default`ness which is the main goal of the PR. ----------------------- We are now very close to fully fusing the entirely of item parsing and their ASTs. To progress further, we must make a decision: should we parse e.g. `default use foo::bar;` and whatnot? Accepting that is likely easiest from a parsing perspective, as it does not require using look-ahead, but it is perhaps not too onerous to only accept it for `fn`s (and all their various qualifiers), `const`s, `static`s, and `type`s. r? @petrochenkov

2019-11-06Make doc comments cheaper with `AttrKind`.Nicholas Nethercote-2/+2
`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.

rustc: Stabilize options for pipelined compilation This commit stabilizes options in the compiler necessary for Cargo to enable "pipelined compilation" by default. The concept of pipelined compilation, how it's implemented, and what it means for rustc are documented in #60988. This PR is coupled with a PR against Cargo (rust-lang/cargo#7143) which updates Cargo's support for pipelined compliation to rustc, and also enables support by default in Cargo. (note that the Cargo PR cannot land until this one against rustc lands). The technical changes performed here were to stabilize the functionality proposed in #60419 and #60987, the underlying pieces to enable pipelined compilation support in Cargo. The issues have had some discussion during stabilization, but the newly stabilized surface area here is: * A new `--json` flag was added to the compiler. * The `--json` flag can be passed multiple times. * The value of the `--json` flag is a comma-separated list of directives. * The `--json` flag cannot be combined with `--color` * The `--json` flag must be combined with `--error-format=json` * The acceptable list of directives to `--json` are: * `diagnostic-short` - the `rendered` field of diagnostics will have a "short" rendering matching `--error-format=short` * `diagnostic-rendered-ansi` - the `rendered` field of diagnostics will be colorized with ansi color codes embedded in the string field * `artifacts` - JSON blobs will be emitted for artifacts being emitted by the compiler The unstable `-Z emit-artifact-notifications` and `--json-rendered` flags have also been removed during this commit as well. Closes #60419 Closes #60987 Closes #60988
