2019-06-10syntax: Use `MultiItemModifier` for built-in derivesVadim Petrochenkov-25/+22

2019-06-10Don't suggest using \r in raw stringsIgor Matuszewski-1/+7
2019-06-10Stabilize underscore_const_names.Mazdak Farrokhzad-11/+3
2019-06-10Special-case literals in `parse_bottom_expr`.Nicholas Nethercote-10/+22
This makes parsing faster, particularly for code with large constants, for two reasons: - it skips all the keyword comparisons for literals; - it replaces the unnecessary `parse_literal_maybe_minus` call with `parse_lit`, avoiding an unnecessary allocation via `mk_expr`.
2019-06-09Auto merge of #61229 - Centril:stabilize-repr_align_enum, r=nagisabors-14/+3
Stabilize #![feature(repr_align_enum)] in Rust 1.37.0 On an `enum` item, you may now write: ```rust #[repr(align(X))] enum Foo { // ... } ``` This has equivalent effects to first defining: ```rust #[repr(align(X))] struct AlignX<T>(T); ``` and then using `AlignX<Foo>` in `Foo`'s stead. r? @nagisa

2019-06-08Remove redundant, commented out codeIgor Matuszewski-6/+0
It was commented out as part of https://github.com/rust-lang/rust/commit/8a8e497ae786ffc032c1e68fc23da0edcf6fa5e3. Done probably by accident, since the code in question was moved to a match arm, along with newly introduced logic to detect bare CRs in raw strings.

2019-06-08Rollup merge of #61616 - petrochenkov:parsderef, r=oli-obkMazdak Farrokhzad-262/+252
parser: Remove `Deref` impl from `Parser` Follow up to https://github.com/rust-lang/rust/pull/61541 You have to write `self.token.span` instead of `self.span` in the parser now, which is not nice, but not too bad either, I guess. Not sure. Probably still better than people using both and being confused about the definition point of `span`. r? @oli-obk @estebank

Make tuple constructors real const fns Mir construction special cases `Ctor(...)` to be lowered as `Ctor { 0: ... }`, which means this doesn't come up much in practice, but it seems inconsistent not to allow this. r? @oli-obk
