2015-01-16syntax: Feature gate #[start] and #[main]Alex Crichton-0/+14
These two attributes are used to change the entry point into a Rust program, but for now they're being put behind feature gates until we have a chance to think about them a little more. The #[start] attribute specifically may have its signature changed. This is a breaking change to due the usage of these attributes generating errors by default now. If your crate is using these attributes, add this to your crate root: #![feature(start)] // if you're using the #[start] attribute #![feature(main)] // if you're using the #[main] attribute cc #20064
2015-01-16auto merge of #21008 : huonw/rust/trait-suggestions, r=nikomatsakisbors-0/+3
For a call like `foo.bar()` where the method `bar` can't be resolved, the compiler will search for traits that have methods with name `bar` to give a more informative error, providing a list of possibilities. Closes #7643.
2015-01-16auto merge of #21162 : apasel422/rust/issue-16530, r=huonwbors-6/+2
This fixes #16530 by hashing nullary structs [the same way as the empty tuple] (https://github.com/rust-lang/rust/blob/master/src/libcore/hash/mod.rs#L185). Other approaches are possible, but this was the simplest.

2015-01-15rollup merge of #21199: dotdash/decode_lambaAlex Crichton-4/+3
Currently, we build a closure that does nothing but pass its argument through to another function, this is rather wasteful and creates lots of unnecessary closures.

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.

2015-01-08Improvements to feature stagingBrian Anderson-1/+1
This gets rid of the 'experimental' level, removes the non-staged_api case (i.e. stability levels for out-of-tree crates), and lets the staged_api attributes use 'unstable' and 'deprecated' lints. This makes the transition period to the full feature staging design a bit nicer.
