2019-08-24Improve Rustdoc's handling of procedural macrosAaron Hill-7/+11
Fixes #58700 Fixes #58696 Fixes #49553 Fixes #52210 This commit removes the special rustdoc handling for proc macros, as we can now retrieve their span and attributes just like any other item. A new command-line option is added to rustdoc: `--crate-type`. This takes the same options as rustc's `--crate-type` option. However, all values other than `proc-macro` are treated the same. This allows Rustdoc to enable 'proc macro mode' when handling a proc macro crate. In compiletest, a new 'rustdoc-flags' option is added. This allows us to pass in the '--proc-macro-crate' flag in the absence of Cargo. I've opened [an additional PR to Cargo](https://github.com/rust-lang/cargo/pull/7159) to support passing in this flag. These two PRS can be merged in any order - the Cargo changes will not take effect until the 'cargo' submodule is updated in this repository.

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.

2019-07-11Only error about MSVC + PGO + unwind if we're generating codeWesley Wiser-2/+5
When `rustc` is invoked with the `--print` argument, we don't actually generate any code (unless it's the `native-static-libs` option). So we don't need to error our in this case since there's no risk of generating either LLVM assertions or corrupted binaries.

Stabilize support for Profile-guided Optimization This PR makes profile-guided optimization available via the `-C profile-generate` / `-C profile-use` pair of commandline flags and adds end-user documentation for the feature to the [rustc book](https://doc.rust-lang.org/rustc/). The PR thus ticks the last two remaining checkboxes of the [stabilization tracking issue](https://github.com/rust-lang/rust/issues/59913). From the tracking issue: > Profile-guided optimization (PGO) is a common optimization technique for ahead-of-time compilers. It works by collecting data about a program's typical execution (e.g. probability of branches taken, typical runtime values of variables, etc) and then uses this information during program optimization for things like inlining decisions, machine code layout, or indirect call promotion. If you are curious about how this can be used, there is a rendered version of the documentation this PR adds available [here]( https://github.com/michaelwoerister/rust/blob/stabilize-pgo/src/doc/rustc/src/profile-guided-optimization.md). r? @alexcrichton cc @rust-lang/compiler

2019-06-05librustc_errors: Rename AnnotateRs -> AnnotateSnippetPhilipp Hansch-5/+5
The proper name of the library is `annotate-snippet`, not `annotate-rs`, this commit should get rid of any confusing `AnnotateRs` names. 1. Renames `annotate_rs_emitter.rs` to `annotate_snippet_emitter_writer.rs` so that the difference between the `Emitter` trait and the implementers is more clear. 2. Renames `AnnotateRsEmitterWriter` to `AnnotateSnippetEmitterWriter` 3. Renames `HumanReadableErrorType::AnnotateRs` to `HumanReadableErrorType::AnnotateSnippet`

Emit error when trying to use PGO in conjunction with unwinding on Windows. This PR makes `rustc` emit an error when trying use PGO in conjunction with `-Cpanic=unwind` on Windows, isn't supported by LLVM yet. The error messages points to https://github.com/rust-lang/rust/issues/61002, which documents this known limitation.
