2018-12-20Stabilize `Rc`, `Arc` and `Pin` as method receiversMichael Hewson-22/+34
This lets you write methods using `self: Rc<Self>`, `self: Arc<Self>`, `self: Pin<&mut Self>`, `self: Pin<Box<Self>`, and other combinations involving `Pin` and another stdlib receiver type, without needing the `arbitrary_self_types`. Other user-created receiver types can be used, but they still require the feature flag to use. This is implemented by introducing a new trait, `Receiver`, which the method receiver's type must implement if the `arbitrary_self_types` feature is not enabled. To keep composed receiver types such as `&Arc<Self>` unstable, the receiver type is also required to implement `Deref<Target=Self>` when the feature flag is not enabled. This lets you use `self: Rc<Self>` and `self: Arc<Self>` in stable Rust, which was not allowed previously. It was agreed that they would be stabilized in #55786. `self: Pin<&Self>` and other pinned receiver types do not require the `arbitrary_self_types` feature, but they cannot be used on stable because `Pin` still requires the `pin` feature.
2018-12-18Auto merge of #56160 - oli-obk:const_fn_let, r=nikomatsakisbors-8/+89
Fix various aspects around `let` bindings inside const functions * forbid `let` bindings in const contexts that use short circuiting operators * harden analysis code against derefs of mutable references Initially this PR was about stabilizing `let` bindings, but too many flaws were exposed that need some more testing on nightly

2018-12-14Auto merge of #56351 - davidtwco:issue-55396-stabilize-linker-flavor, r=nagisabors-28/+0
Stabilize `linker-flavor` flag. Part of #55396. This commit moves the linker-flavor flag from a debugging option to a codegen option, thus stabilizing it. There are no feature flags associated with this flag. r? @nagisa

2018-12-06Auto merge of #56392 - petrochenkov:regensym, r=oli-obkbors-15/+27
Delay gensym creation for "underscore items" (`use foo as _`/`const _`) until name resolution So they cannot be cloned by macros. See https://github.com/rust-lang/rust/pull/56303 for the discussion. Mostly fix cross-crate use of underscore items by inverting the "gensyms are lost in metadata" bug as described in https://github.com/rust-lang/rust/pull/56303#issuecomment-442464695. Fix unused import warnings for single-segment imports (first commit) and `use crate_name as _` imports (as specified in https://github.com/rust-lang/rust/pull/56303#issuecomment-442274118). Prohibit accidentally implemented `static _: TYPE = EXPR;` (cc https://github.com/rust-lang/rust/pull/55983). Add more tests for `use foo as _` imports.
2018-12-06Rollup merge of #56362 - varkor:stabilise-exhaustive-integer-patterns, ↵Pietro Albini-0/+29
r=nikomatsakis Stabilise exhaustive integer patterns This is dependent on the FCP for https://github.com/rust-lang/rfcs/pull/2591 being completed, but that should happen tomorrow, so there's little harm in opening this PR early. Closes #50907.

We take stability seriously, so we shy away from making even seemingly "trivial" features insta-stable.
2018-10-27Correct alignment of atomic types and (re)add Atomic{I,U}128Oliver Middleton-7/+43
LLVM requires that atomic loads and stores be aligned to at least the size of the type.
