2015-11-26Add syntax support for attributes on expressions and all syntaxMarvin Löbel-10/+37
nodes in statement position. Extended #[cfg] folder to allow removal of statements, and of expressions in optional positions like expression lists and trailing block expressions. Extended lint checker to recognize lint levels on expressions and locals.

2015-11-23Auto merge of #29952 - petrochenkov:depr, r=brsonbors-1/+1
Part of https://github.com/rust-lang/rust/issues/29935 The deprecation lint is still called "deprecated", so people can continue using `#[allow(deprecated)]` and similar things.

2015-11-13Move the panicking parse functions out of the parserKyle Mayes-3/+52
Since these functions are only used by the AST quoting syntax extensions, they should be there instead of in the parser.
2015-11-13Auto merge of #29761 - eefriedman:rename-nopanic, r=sanxiynbors-21/+21
Just `sed s/_nopanic//g`. Hopefully makes libsyntax a bit more readable.
2015-11-12Auto merge of #29780 - KyleMayes:quote-ext, r=nrcbors-0/+63
This is my first code contribution to Rust, so I'm sure there are some issues with the changes I've made. I've added the `quote_arg!`, `quote_block!`, `quote_path!`, and `quote_meta_item!` quasiquoting macros. From my experience trying to build AST in compiler plugins, I would like to be able to build any AST piece with a quasiquoting macro (e.g., `quote_struct_field!` or `quote_variant!`) and then use those AST pieces in other quasiquoting macros, but this pull request just adds some of the low-hanging fruit. I'm not sure if these additions are desirable, and I'm sure these macros can be implemented in an external crate if not.

2015-11-09syntax: Use `let _` in #[derive(Debug)]Alex Crichton-4/+21

Closes https://github.com/rust-lang/rust/issues/29145 [breaking-change], needs a crater run.

2015-10-16Auto merge of #29014 - petrochenkov:stability, r=brsonbors-1/+1
Stricter checking of stability attributes + enforcement of their invariants at compile time (+ removed dead file librustc_front/attr.rs) I intended to enforce use of `reason` for unstable items as well (it normally presents for new items), but it turned out too intrusive, many older unstable items don't have `reason`s. r? @aturon I'm studying how stability works and do some refactoring along the way, so it's probably not the last PR.

This is a [breaking change]. @brson could you do a Crater run with this PR please? Lets not land till Crater says its OK. This was discussed at https://internals.rust-lang.org/t/does-anyone-use-the-push-pop-unsafe-macros/2702
