2019-06-23Remove built-in derive macros `Send` and `Sync`Vadim Petrochenkov-10/+0
2019-06-23Fix meta-variable binding errors in macrosJulien Cretin-2/+2
The errors are either: - The meta-variable used in the right-hand side is not bound (or defined) in the left-hand side. - The meta-variable used in the right-hand side does not repeat with the same kleene operator as its binder in the left-hand side. Either it does not repeat enough, or it uses a different operator somewhere. This change should have no semantic impact.
2019-06-19Auto merge of #61172 - matthewjasper:cleanup-implied-bounds-lint, r=varkorbors-1/+0
Improve the explicit_outlives_requirements lint * Don't use Strings to compare parameters * Extend the lint to lifetime bounds * Extend the lint to enums and unions * Use the correct span for where clauses in tuple structs * Try to early-out where possible * Remove unnecessary bounds in rustc crates

syntax: Factor out common fields from `SyntaxExtension` variants And some other related cleanups. Continuation of https://github.com/rust-lang/rust/pull/61606. This will also help to unblock https://github.com/rust-lang/rust/pull/61877.

Also give them a span in the HIR

Allow attributes in formal function parameters Implements https://github.com/rust-lang/rust/issues/60406. This is my first contribution to the compiler and since this is a large and complex project, I am not fully aware of the consequences of the changes I have made. **TODO** - [x] Forbid some built-in attributes. - [x] Expand cfg/cfg_attr

Use Symbol, Span in libfmt_macros I'm not super happy with this, personally, but I think it might be a decent start -- happy to take suggestions as to how to expand this or change things further. r? @estebank Fixes #60795

2019-06-10syntax: Remove `SyntaxExtension::DeclMacro`Vadim Petrochenkov-0/+4
It's a less powerful duplicate of `SyntaxExtension::NormalTT`
2019-06-10syntax: Use `MultiItemModifier` for built-in derivesVadim Petrochenkov-4/+20
2019-06-09Introduce InnerSpan abstractionMark Rousskov-20/+20
This should be used when trying to get at subsets of a larger span, especially when the larger span is not available in the code attempting to work with those subsets (especially common in the fmt_macros crate). This is usually a good replacement for (BytePos, BytePos) and (usize, usize) tuples. This commit also removes from_inner_byte_pos, since it took usize arguments, which is error prone.

2019-06-08Rollup merge of #61616 - petrochenkov:parsderef, r=oli-obkMazdak Farrokhzad-4/+4
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
