2015-01-24Auto merge of #21079 - huonw:chained-cmp-tweaks, r=pnkfelixbors-2/+2
First commit is mindless groundwork for the second one, to make the spans (arguably) nicer. ### before ``` require-parens-for-chained-comparison.rs:14:20: 14:22 error: Chained comparison operators require parentheses require-parens-for-chained-comparison.rs:14 false == false == false; ^~ require-parens-for-chained-comparison.rs:17:16: 17:17 error: Chained comparison operators require parentheses require-parens-for-chained-comparison.rs:17 false == 0 < 2; ^ require-parens-for-chained-comparison.rs:20:8: 20:9 error: Chained comparison operators require parentheses require-parens-for-chained-comparison.rs:20 f<X>(); ^ require-parens-for-chained-comparison.rs:20:8: 20:9 help: Use ::< instead of < if you meant to specify type arguments. require-parens-for-chained-comparison.rs:20 f<X>(); ^ ``` ### after ``` require-parens-for-chained-comparison.rs:14:11: 14:22 error: chained comparison operators require parentheses require-parens-for-chained-comparison.rs:14 false == false == false; ^~~~~~~~~~~ require-parens-for-chained-comparison.rs:17:11: 17:17 error: chained comparison operators require parentheses require-parens-for-chained-comparison.rs:17 false == 0 < 2; ^~~~~~ require-parens-for-chained-comparison.rs:20:6: 20:9 error: chained comparison operators require parentheses require-parens-for-chained-comparison.rs:20 f<X>(); ^~~ require-parens-for-chained-comparison.rs:20:6: 20:9 help: use `::<...>` instead of `<...>` if you meant to specify type arguments require-parens-for-chained-comparison.rs:20 f<X>(); ^~~ ```

2015-01-21rollup merge of #21340: pshc/libsyntax-no-more-intsAlex Crichton-108/+108
Collaboration with @rylev! I didn't change `int` in the [quasi-quoter](https://github.com/pshc/rust/blob/99ae1a30f3ca28c0f7e431620560d30e44627124/src/libsyntax/ext/quote.rs#L328), because I'm not sure if there will be adverse effects. Addresses #21095.

2015-01-15rollup merge of #21127: erickt/opt-stackAlex Crichton-174/+252
libsyntax compiled without optimization uses a lot of stack, which can cause it to run out of stack space. This PR factors out some arm handlers from `print_expr` as well as converts `advance_left` into a loop. This helps to cut down on the stack usage.

2015-01-05Change `&` pat to only work with &T, and `&mut` with &mut T.Huon Wilson-1/+4
This implements RFC 179 by making the pattern `&<pat>` require matching against a variable of type `&T`, and introducing the pattern `&mut <pat>` which only works with variables of type `&mut T`. The pattern `&mut x` currently parses as `&(mut x)` i.e. a pattern match through a `&T` or a `&mut T` that binds the variable `x` to have type `T` and to be mutable. This should be rewritten as follows, for example, for &mut x in slice.iter() { becomes for &x in slice.iter() { let mut x = x; Due to this, this is a [breaking-change] Closes #20496.

2014-12-30Remove ExprSlice by hacking the compilerNick Cameron-19/+1
[breaking-change] The `mut` in slices is now redundant. Mutability is 'inferred' from position. This means that if mutability is only obvious from the type, you will need to use explicit calls to the slicing methods.
2014-12-30Add hypothetical support for ranges with only an upper boundNick Cameron-1/+3
Note that this doesn't add the surface syntax.
2014-12-29Slash the ast::Stmt type from 104 to 24 bytes.Huon Wilson-1/+1
(on platforms with 64-bit pointers.) The StmtMac variant is rather large and also fairly rare, so let's optimise the common case.

2014-12-26Accept `?Sized` as well as `Sized?`Nick Cameron-11/+11
Includes a bit of refactoring to store `?` unbounds as bounds with a modifier, rather than in their own world, in the AST at least.
