ExpnInfo/MacroBacktrace/DiagnosticSpanMacroExpansion We have to deal with dummy spans anyway Remove def-site span from expander interfaces. It's not used by the expansion infra, only by specific expanders, which can keep it themselves if they want it.
2019-07-07rustc: Remove `dylib` crate type from most rustc cratesAlex Crichton-2/+1
Now that procedural macros no longer link transitively to libsyntax, this shouldn't be needed any more! This commit is an experiment in removing all dynamic libraries from rustc except for librustc_driver itself. Let's see how far we can get with that!

Implement another internal lints cc #49509 This adds ~~two~~ one internal lint~~s~~: 1. LINT_PASS_IMPL_WITHOUT_MACRO: Make sure, that the `{declare,impl}_lint_pass` macro is used to implement lint passes. cc #59669 2. ~~USAGE_OF_TYCTXT_AND_SPAN_ARGS: item 2 on the list in #49509~~ ~~With 2. I wasn't sure, if this lint should be applied everywhere. That means a careful review of 0955835 would be great. Also 73fb9b4 allows this lint on some functions. Should I also apply this lint there?~~ TODO (not directly relevant for review): - [ ] https://github.com/rust-lang/rust/pull/59316#discussion_r280186517 (not sure yet, if this works or how to query for `rustc_private`, since it's not in [`Features`](https://doc.rust-lang.org/nightly/nightly-rustc/syntax/feature_gate/struct.Features.html) :thinking: cc @eddyb) - [x] https://github.com/rust-lang/rust/pull/61735#discussion_r292389870 - [x] Check explicitly for the `{declare,impl}_lint_pass!` macros r? @oli-obk

libsyntax: Fix some Clippy warnings When I was working on it before a lot of these popped up in the RLS so I figured I'll send a small patch fixing only the (hopefully) uncontroversial ones. Others that could be also fixed included also [`clippy::print_with_newline`](https://rust-lang.github.io/rust-clippy/master/index.html#print_with_newline) and [`clippy::cast_lossless`](https://rust-lang.github.io/rust-clippy/master/index.html#cast_lossless). Should I add them as well? since most of it touches libsyntax... r? @petrochenkov

2019-06-05librustc_errors: Rename AnnotateRs -> AnnotateSnippetPhilipp Hansch-13/+13
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`

2019-06-04Add new diagnostic writer using annotate-snippet libraryPhilipp Hansch-2/+216
This adds a new diagnostic writer `AnnotateRsEmitterWriter` that uses the [`annotate-snippet`][as] library to print out the human readable diagnostics. The goal is to eventually switch over to using the library instead of maintaining our own diagnostics output. This commit does *not* add all the required features to the new diagnostics writer. It is only meant as a starting point so that other people can contribute as well. [as]: https://github.com/rust-lang/annotate-snippets-rs
2019-05-28librustc_errors: Move annotation collection to own implPhilipp Hansch-167/+174
Extracted from work on #59346. This moves the annotation collection to the `FileWithAnnotatedLines` impl to allow re-use in a separate EmitterWriter.
2019-05-23Rollup merge of #61073 - phansch:remove_unused_annotation_style, r=matthewjasperMazdak Farrokhzad-2/+1
librustc_errors: Remove unused annotation style `OldSchoolNoteText` I could not find any references to it and the `snippet` module does not seem to be exported publicly, so I think it can be safely removed. This was originally removed in 17bd76a51 and I'm not sure why it is still there.

2019-05-02introduce unescape moduleAleksey Kladov-1/+1
Currently, we deal with escape sequences twice: once when we lex a string, and a second time when we unescape literals. This PR aims to remove this duplication, by introducing a new `unescape` mode as a single source of truth for character escaping rules
2019-04-30In JSON output, emit a directive after metadata is generated.Nicholas Nethercote-8/+22
To implement pipelining, Cargo needs to know when metadata generation is finished. This commit adds code to do that. Unfortunately, metadata file writing currently occurs very late during compilation, so pipelining won't produce a speed-up. Moving metadata file writing earlier will be a follow-up. The change involves splitting the existing `Emitter::emit` method in two: `Emitter::emit_diagnostic` and `Emitter::emit_directive`. The JSON directives look like this: ``` {"directive":"metadata file written: liba.rmeta"} ``` The functionality is behind the `-Z emit-directives` option, and also requires `--error-format=json`.
