2019-10-18Rollup merge of #65552 - JohnTitor:use-bitwise-not, r=Dylan-DPCTyler Mandry-1/+1
Clarify diagnostics when using `~` as a unary op It seems we prefer `bitwise not` to `bitwise negation`. Fixes #57239 r? @estebank

nnethercote:avoid-unnecessary-TokenTree-to-TokenStream-conversions, r=petrochenkov Avoid unnecessary `TokenTree` to `TokenStream` conversions A `TokenStream` contains any number of `TokenTrees`. Therefore, a single `TokenTree` can be promoted to a `TokenStream`. But doing so costs two allocations: one for the single-element `Vec`, and one for the `Lrc`. (An `IsJoint` value also must be added; the default is `NonJoint`.) The current code converts `TokenTree`s to `TokenStream`s unnecessarily in a few places. This PR removes some of these unnecessary conversions, both simplifying the code and speeding it up. r? @petrochenkov

2019-10-14Rollup merge of #65410 - Centril:intersection-pat-recover, r=davidtwco,varkorTyler Mandry-0/+60
syntax: add parser recovery for intersection- / and-patterns `p1 @ p2` Fixes https://github.com/rust-lang/rust/issues/65400. The recovery comes in two flavors: 1. We know that `p2` is a binding so we can invert as `p2 @ p1`: ```rust error: pattern on wrong side of `@` --> $DIR/intersection-patterns.rs:13:9 | LL | Some(x) @ y => {} | -------^^^- | | | | | binding on the right, should be to the left | pattern on the left, should be to the right | help: switch the order: `y @ Some(x)` ``` 2. Otherwise we emit a generic diagnostic for the lack of support for intersection patterns: ```rust error: left-hand side of `@` must be a binding --> $DIR/intersection-patterns.rs:23:9 | LL | Some(x) @ Some(y) => {} | -------^^^------- | | | | | also a pattern | interpreted as a pattern, not a binding | = note: bindings are `x`, `mut x`, `ref x`, and `ref mut x` ``` For more on and-patterns, see e.g. https://docs.microsoft.com/en-us/dotnet/fsharp/language-reference/pattern-matching#and-pattern. r? @davidtwco cc @varkor @lzutao

Remove implicit dependencies on syntax::pprust Part of https://github.com/rust-lang/rust/pull/65324. The main goal here is to facilitate the eventual move of pprust out from libsyntax and because an AST definition typically should not depend on its pretty printer. r? @estebank
