2017-07-11Auto merge of #42913 - kennytm:fix-40569-ident-without-backtrack, r=jseyfriedbors-4/+70
Only match a fragment specifier the if it starts with certain tokens. When trying to match a fragment specifier, we first predict whether the current token can be matched at all. If it cannot be matched, don't bother to push the Earley item to `bb_eis`. This can fix a lot of issues which otherwise requires full backtracking (#42838). In this PR the prediction treatment is not done for `:item`, `:stmt` and `:tt`, but it could be expanded in the future. Fixes #24189. Fixes #26444. Fixes #27832. Fixes #34030. Fixes #35650. Fixes #39964. Fixes the 4th comment in #40569. Fixes the issue blocking #40984.

2017-07-06Auto merge of #42727 - alexcrichton:allocators-new, r=eddybbors-0/+6
rustc: Implement the #[global_allocator] attribute This PR is an implementation of [RFC 1974] which specifies a new method of defining a global allocator for a program. This obsoletes the old `#![allocator]` attribute and also removes support for it. [RFC 1974]: https://github.com/rust-lang/rfcs/pull/1974 The new `#[global_allocator]` attribute solves many issues encountered with the `#![allocator]` attribute such as composition and restrictions on the crate graph itself. The compiler now has much more control over the ABI of the allocator and how it's implemented, allowing much more freedom in terms of how this feature is implemented. cc #27389

trace_macro: Show both the macro call and its expansion. #42072. See #42072 for the initial motivation behind this. The change is not the minimal fix, but I want this behavior almost every time I use `trace_macros`.

2017-05-24Rollup merge of #42071 - nrc:parse-mods, r=nikomatsakisMark Simulacrum-4/+8
Add an option to the parser to avoid parsing out of line modules This is useful if parsing from stdin or a String and don't want to try and read in a module from another file. Instead we just leave a stub in the AST.

Fix #35829 (`quote!()` does not handle `br#"…"#`) Fix issue #35829 (syntax extension's `quote_expr!()` does not handle `b"…"` and proc_macro's `quote!()` does not handle `r#"…"#`) * Handles `b"…"`, `br#"…"#` and `...` for `quote_expr!()`. * Refactored the match statement to allow it to complain loudly on any unhandled token. * Similarly, proc_macro's `quote!()` did not handle `br#"…"#` or `r#"…"#`, so this PR fixes it too.

Fix some clippy warnings in libsyntax This is mostly removing stray ampersands, needless returns and lifetimes. Basically a lot of small changes.
2017-05-16Auto merge of #41907 - est31:macro_unused, r=jseyfriedbors-3/+11
Add lint for unused macros Addresses parts of #34938, to add a lint for unused macros. We now output warnings by default when we encounter a macro that we didn't use for expansion. Issues to be resolved before this PR is ready for merge: - [x] fix the NodeId issue described above - [x] remove all unused macros from rustc and the libraries or set `#[allow(unused_macros)]` next to them if they should be kept for some reason. This is needed for successful boostrap and bors to accept the PR. -> #41934 - [x] ~~implement the full extent of #34938, that means the macro match arm checking as well.~~ *let's not do this for now*

2017-05-13Support #[allow] etc logic on a per macro levelest31-3/+7
This commit extends the current unused macro linter to support directives like #[allow(unused_macros)] or #[deny(unused_macros)] directly next to the macro definition, or in one of the modules the macro is inside. Before, we only supported such directives at a per crate level, due to the crate's NodeId being passed to session.add_lint. We also had to implement handling of the macro's NodeId in the lint visitor.

2017-05-08Rollup merge of #41520 - estebank:trace-macro, r=nikomatsakisCorey Farwell-5/+19
Use diagnostics for trace_macro instead of println When using `trace_macro`, use `span_label`s instead of `println`: ```rust note: trace_macro --> $DIR/trace-macro.rs:14:5 | 14 | println!("Hello, World!"); | ^^^^^^^^^^^^^^^^^^^^^^^^^^ | = note: expands to `println! { "Hello, World!" }` = note: expands to `print! { concat !
