2019-11-07syntax: use distinct FloatTy from rustc_target.Mazdak Farrokhzad-1/+0
We also sever syntax's dependency on rustc_target as a result. This should slightly improve pipe-lining. Moreover, some cleanup is done in related code.

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.
2019-11-06Remove unnecessary `Deref` impl for `Attribute`.Nicholas Nethercote-1/+1
This kind of thing just makes the code harder to read.

2019-07-30Auto merge of #62766 - alexcrichton:stabilize-pipelined-compilation, r=oli-obkbors-1/+1
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.

The Dumper no longer has anything to do specifically with JSON, it merely represents processing into an `Analysis` output.
