2019-08-23Remove default macro transparenciesVadim Petrochenkov-21/+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.
2019-08-23hygiene: Require passing transparency explicitly to `apply_mark`Vadim Petrochenkov-41/+47
2019-08-23Audit uses of `apply_mark` in built-in macrosVadim Petrochenkov-17/+25
Replace them with equivalents of `Span::{def_site,call_site}` from proc macro API. The new API is much less error prone and doesn't rely on macros having default transparency.

2019-08-21Rollup merge of #63717 - petrochenkov:eager, r=matthewjasperMazdak Farrokhzad-9/+8
Fix nested eager expansions in arguments of `format_args` Fixes https://github.com/rust-lang/rust/issues/63460 Fixes https://github.com/rust-lang/rust/issues/63685 (regression from making `format_args` opaque - https://github.com/rust-lang/rust/pull/63114) r? @matthewjasper
2019-08-21Rollup merge of #63762 - rust-lang:fix-async-date, r=Mark-SimulacrumMazdak Farrokhzad-1/+1
`async_await` was stabilized in 1.39.0, not 1.38.0. r? @Mark-Simulacrum
2019-08-21Rollup merge of #63759 - Centril:parse-default-async-fn, r=petrochenkovMazdak Farrokhzad-0/+1
Allow 'default async fn' to parse. - Parse default async fn. Fixes #63716. (`cherry-pick`ed from 3rd commit in https://github.com/rust-lang/rust/pull/63749.) r? @petrochenkov
2019-08-21Rollup merge of #63755 - Centril:simplify-prexp-gating, r=petrochenkovMazdak Farrokhzad-28/+34
Use dedicated type for spans in pre-expansion gating. - Simplify the overall pre-expansion gating "experience".
2019-08-21Rollup merge of #63721 - Mark-Simulacrum:decouple-error-index, r=matthewjasperMazdak Farrokhzad-124/+4
Do not emit JSON dumps of diagnostic codes This decouples the error index generator from libsyntax for the most part (though it still depends on librustdoc for the markdown parsing and generation). Fixes #34588
2019-08-21resolve/expand: Rename some things for clarity and add commentsVadim Petrochenkov-4/+7
2019-08-21expand: Do not do questionable span adjustment before eagerly expanding an ↵Vadim Petrochenkov-4/+1
expression Maybe it made sense when it was introduced, but now it's doing something incorrect.
2019-08-21expand: Keep the correct current expansion ID for eager expansionsVadim Petrochenkov-1/+0
Solve the problem of `ParentScope` entries for eager expansions not exising in the resolver map by creating them on demand.

2019-08-20Rollup merge of #63209 - Centril:stabilize-async-await, r=cramertjMazdak Farrokhzad-17/+2
Stabilize `async_await` in Rust 1.39.0 Here we stabilize: - free and inherent `async fn`s, - the `<expr>.await` expression form, - and the `async move? { ... }` block form. Closes https://github.com/rust-lang/rust/issues/62149. Closes https://github.com/rust-lang/rust/issues/50547.

2019-08-20Remove serialization of diagnostics to filesMark Rousskov-124/+4
This is no longer used by the index generator and was always an unstable compiler detail, so strip it out. This also leaves in RUSTC_ERROR_METADATA_DST since the stage0 compiler still needs it to be set.

Normalize newlines when loading files Fixes #62865
2019-08-18Auto merge of #61708 - dlrobertson:or-patterns-0, r=centrilbors-28/+80
Initial implementation of or-patterns An incomplete implementation of or-patterns (e.g. `Some(0 | 1)` as a pattern). This patch set aims to implement initial parsing of `or-patterns`. Related to: #54883 CC @alexreg @varkor r? @Centril

2019-08-17initial implementation of or-pattern parsingDan Robertson-40/+59
Initial implementation of parsing or-patterns e.g., `Some(Foo | Bar)`. This is a partial implementation of RFC 2535.

2019-08-17Remove SyntaxContext from {ast, hir}::{GlobalAsm, InlineAsm}Matthew Jasper-4/+2
We now store it in the `Span` of the expression or item.

2019-08-16Rollup merge of #63525 - matklad:centraliza-file-loading, r=petrochenkovMazdak Farrokhzad-8/+25
Make sure that all file loading happens via SourceMap That way, callers don't need to repeat "let's add this to sm manually for tracking dependencies" trick. It should make it easier to switch to using `FileLoader` for binary files in the future as well cc #62948 r? @petrochenkov
2019-08-15hygiene: `ExpnInfo` -> `ExpnData`Vadim Petrochenkov-28/+28
For naming consistency with everything else in this area
2019-08-15syntax_pos: Remove the duplicate global editionVadim Petrochenkov-29/+6
It was introduced to avoid going through `hygiene_data`, but now it's read only once, when `ParseSess` is created, so going through a lock is ok.
2019-08-15hygiene: Merge `ExpnInfo` and `InternalExpnData`Vadim Petrochenkov-8/+12
2019-08-15hygiene: Remove `Option`s from functions returning `ExpnInfo`Vadim Petrochenkov-24/+17
The expansion info is not optional and should always exist
2019-08-15`Ident::with_empty_ctxt` -> `Ident::with_dummy_span`Vadim Petrochenkov-13/+13
`Ident` has had a full span rather than just a `SyntaxContext` for a long time now.
2019-08-15syntax_pos: `NO_EXPANSION`/`SyntaxContext::empty()` -> `SyntaxContext::root()`Vadim Petrochenkov-24/+22
For consistency with `ExpnId::root`. Also introduce a helper `Span::with_root_ctxt` for creating spans with `SyntaxContext::root()` context
