2019-09-07Rollup merge of #64243 - petrochenkov:cmdattr, r=alexcrichtonMazdak Farrokhzad-1/+1
Move injection of attributes from command line to `libsyntax_ext` Just a tiny bit of code generation that wasn't moved into `libsyntax_ext` in https://github.com/rust-lang/rust/pull/62771.

reduce visibility
2019-09-07Rollup merge of #64192 - estebank:turbofish-madness, r=petrochenkovMazdak Farrokhzad-2/+5
Bail out when encountering likely missing turbofish in parser When encountering a likely intended turbofish without `::`, bubble up the diagnostic instead of emitting it to allow the parser to recover more gracefully and avoid uneccessary type errors that are likely to be wrong. Fix #61329.

2019-09-05or-patterns: syntax: adjust parser removing a hack.Mazdak Farrokhzad-15/+3
Fuse `parse_top_pat` and `parse_top_pat_unpack` into just `parse_top_pat`.
2019-09-03Move path parsing earlier.Nicholas Nethercote-26/+30
It's a hot enough path that moving it slightly earlier gives a tiny but easy speedup.
2019-08-30Auto merge of #63402 - estebank:strip-margin, r=oli-obkbors-25/+53
Strip code to the left and right in diagnostics for long lines Fix #62999.
2019-08-29Rollup merge of #63945 - Centril:recover-mut-pat, r=estebankMazdak Farrokhzad-55/+149
Recover `mut $pat` and other improvements - Recover on e.g. `mut Foo(x, y)` and suggest `Foo(mut x, mut y)`. Fixes https://github.com/rust-lang/rust/issues/63764. - Recover on e.g. `let mut mut x;` - Recover on e.g. `let keyword` and `let keyword(...)`. - Cleanups in `token.rs` with `fn is_non_raw_ident_where` and friends.

Propagate spans and attributes from proc macro definitions Thanks to https://github.com/rust-lang/rust/pull/63269 we now have spans and attributes from proc macro definitions available in metadata. However, that PR didn't actually put them into use! This PR finishes that work. Attributes `rustc_macro_transparency`, `allow_internal_unstable`, `allow_internal_unsafe`, `local_inner_macros`, `rustc_builtin_macro`, `stable`, `unstable`, `rustc_deprecated`, `deprecated` now have effect when applied to proc macro definition functions. From those attributes only `deprecated` is both stable and supposed to be used in new code. (`#![staged_api]` still cannot be used in proc macro crates for unrelated reasons though.) `Span::def_site` from the proc macro API now returns the correct location of the proc macro definition. Also, I made a mistake in https://github.com/rust-lang/rust/pull/63269#discussion_r312702919, loaded proc macros didn't actually use the resolver cache. This PR fixes the caching issue, now proc macros go through the `Resolver::macro_map` cache as well. (Also, the first commit turns `proc_macro::quote` into a regular built-in macro to reduce the number of places where `SyntaxExtension`s need to be manually created.)

Which is no longer dummy and is available from metadata now.
