2015-02-16Address the other cases of #22234; fix #22234.Felix S. Klock II-6/+32
The other cases: `concat_idents!`, `log_syntax!`, and `trace_macros!`, (these macros, with `asm!`, are handled (eagerly) in feature_gate.rs).

2015-02-15Rollup merge of #22277 - pnkfelix:reference-update-feature-gate-list, ↵Manish Goregaokar-0/+1
r=steveklabnik Added all active features to the list in reference.md. Added a second note about keeping the reference.md list up-to-date to the bottom of the list, since not everyone (including me) reads the big comment at the top of it. :) Ensured that the feature gate list in reference.md is kept in alphabetical order.

2015-02-13Re-tag `slicing_syntax` as `Accepted`.Felix S. Klock II-1/+1
Rollup merge (373cbab5b08d6630da58f28d2166c19afc327fa6) of PR #20723 accidentally reverted a portion of commit 8327bcc167661c26ca5c6b967309ff745d302329 which shifted `slicing_syntax` from Active to Accepted.

Switch feature-gate checker from `box_syntax` to `box_patterns` when visiting a pattern. (Having to opt into both `box_syntax` and `box_patterns` seemed unnecessary.) [breaking-change]
2015-02-09Use a crate attribute to load pluginsKeegan McAllister-5/+5
#[plugin] #[no_link] extern crate bleh; becomes a crate attribute #![plugin(bleh)] The feature gate is still required. It's almost never correct to link a plugin into the resulting library / executable, because it will bring all of libsyntax and librustc with it. However if you really want this behavior, you can get it with a separate `extern crate` item in addition to the `plugin` attribute. Fixes #21043. Fixes #20769. [breaking-change]

2015-02-06Rollup merge of #21958 - brson:stable-features, r=alexcrichtonManish Goregaokar-5/+10
.... The 'stable_features' lint helps people progress from unstable to stable Rust by telling them when they no longer need a `feature` attribute because upstream Rust has declared it stable. This compares to the existing 'unstable_features' lint, which is used to implement feature staging, and triggers on *any* use of `#[feature]`.

2015-01-20Auto merge of #21257 - alexcrichton:issue-20064, r=pnkfelixbors-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
2015-01-17Feature gate SIMD in FFI, due to unknown ABIs.Huon Wilson-0/+4
I don't know if this handling of SIMD types is correct for the C ABI on all platforms, so lets add an even finer feature gate than just the `simd` one. The `simd` one can be used with (relatively) little risk of complete nonsense, the reason for it is that it is likely that things will change. Using the types in FFI with an incorrect ABI will at best give absolute nonsense results, but possibly cause serious breakage too, so this is a step up in badness, hence a new feature gate.

2015-01-08Added `box_syntax` feature gate; added to std and rustc crates for bootstrap.Felix S. Klock II-0/+12
To avoid using the feauture, change uses of `box <expr>` to `Box::new(<expr>)` alternative, as noted by the feature gate message. (Note that box patterns have no analogous trivial replacement, at least not in general; you need to revise the code to do a partial match, deref, and then the rest of the match.) [breaking-change]

2015-01-06Implement impl reachability rules. This is a [breaking-change]. TypeNiko Matsakis-0/+10
parameters on impls must now also appear in the trait ref, self type, or some associated type declared on the impl. This ensures that they are constrianed in some way and that the semantics of the trait system are well-defined (always a good thing). There are three major ways to fix this error: 1. Convert the trait to use associated types; most often the type parameters are not constrained because they are in fact outputs of the impl. 2. Move the type parameters to methods. 3. Add an additional type parameter to the self type or trait so that the unused parameter can appear there. In some cases, it is not possible to fix the impl because the trait definition needs to be changed first (and that may be out of your control). In that case, for the time being, you can opt out of these rules by using `#[old_impl_check]` on the impl and adding a `#![feature(old_impl_check)]` to your crate declaration.
