2019-09-07Rollup merge of #63919 - matthewjasper:remove-gensymmed, r=petrochenkovMazdak Farrokhzad-0/+8
Use hygiene for AST passes AST passes are now able to have resolve consider their expansions as if they were opaque macros defined either in some module in the current crate, or a fake empty module with `#[no_implicit_prelude]`. * Add an ExpnKind for AST passes. * Remove gensyms in AST passes. * Remove gensyms in`#[test]`, `#[bench]` and `#[test_case]`. * Allow opaque macros to define tests. * Move tests for unit tests to their own directory. * Remove `Ident::{gensym, is_gensymed}` - `Ident::gensym_if_underscore` still exists. cc #60869, #61019 r? @petrochenkov

2019-08-23Remove default macro transparenciesVadim Petrochenkov-1/+0
All transparancies are passed explicitly now. Also remove `#[rustc_macro_transparency]` annotations from built-in macros, they are no longer used. `#[rustc_macro_transparency]` only makes sense for declarative macros now.
2019-08-15hygiene: `ExpnInfo` -> `ExpnData`Vadim Petrochenkov-1/+1
For naming consistency with everything else in this area

2019-07-11hygiene: Make sure each `Mark` has an associated expansion infoVadim Petrochenkov-0/+1
The root expansion was missing one. Expansions created for "derive containers" (see one of the next commits for the description) also didn't get expansion info.
2019-07-11hygiene: Reuse `MacroKind` in `ExpnKind`Vadim Petrochenkov-2/+1
Orthogonality and reuse are good.
2019-07-11Rename some things in `syntax_pos/hygiene`Vadim Petrochenkov-4/+4
More consistent with other naming: ExpnFormat -> ExpnKind ExpnKind::name -> ExpnKind::descr DesugaringKind::name -> DesugaringKind::descr Shorter, no tautology: CompilerDesugaring -> Desugaring CompilerDesugaringKind -> DesugaringKind
2019-07-11Remove `MacroKind::ProcMacroStub`Vadim Petrochenkov-1/+0
It's internal to resolve and always results in `Res::Err` outside of resolve. Instead put `DefKind::Fn`s themselves into the macro namespace, it's ok. Proc macro stubs are items placed into macro namespase for functions that define proc macros. https://github.com/rust-lang/rust/pull/52383 The rustdoc test is changed because the old test didn't actually reproduce the ICE it was supposed to reproduce.

2019-05-07Implement built-in await syntaxTaylor Cramer-0/+1
Adds support for .await under the existing async_await feature gate. Moves macro-like await! syntax to the await_macro feature gate. Removes support for `await` as a non-keyword under the `async_await` feature.

2019-01-14Remove `ThinTokenStream`.Nicholas Nethercote-1/+1
`TokenStream` is now almost identical to `ThinTokenStream`. This commit removes the latter, replacing it with the former.
2018-12-25Remove licensesMark Rousskov-10/+0
2018-12-10Remove `tokenstream::Delimited`.Nicholas Nethercote-3/+3
Because it's an extra type layer that doesn't really help; in a couple of places it actively gets in the way, and overall removing it makes the code nicer. It does, however, move `tokenstream::TokenTree` further away from the `TokenTree` in `quote.rs`. More importantly, this change reduces the size of `TokenStream` from 48 bytes to 40 bytes on x86-64, which is enough to slightly reduce instruction counts on numerous benchmarks, the best by 1.5%. Note that `open_tt` and `close_tt` have gone from being methods on `Delimited` to associated methods of `TokenTree`.

2018-12-02Remove not used `DotEq` tokenyui-knk-1/+0
Currently libproc_macro does not use `DotEq` token. https://github.com/rust-lang/rust/pull/49545 changed libproc_macro to not generate `DotEq` token.
