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: Rename variants of `SyntaxExtension` for consistencyVadim Petrochenkov-8/+9
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
2019-06-07syntax: Treat error literals in more principled wayVadim Petrochenkov-1/+3

2019-05-29Introduce and use `SyntaxContext::outer_expn_info()`.Nicholas Nethercote-1/+1
It reduces two `hygiene_data` accesses to one on some hot paths.
2019-05-27Pass symbols to `ExtCtxt::std_path` instead of strings.Nicholas Nethercote-31/+34
Because this function is hot. Also remove the dead `ty_option` function.
2019-05-27Avoid unnecessary internings.Nicholas Nethercote-57/+47
Most involving `Symbol::intern` on string literals.
2019-05-24Tweak macro parse errors when reaching EOF during macro call parseEsteban Küber-2/+6
- Add detail on origin of current parser when reaching EOF and stop saying "found <eof>" and point at the end of macro calls - Handle empty `cfg_attr` attribute - Reword empty `derive` attribute error

2019-05-17Avoid unnecessary interning in `Ident::from_str()` calls.Nicholas Nethercote-5/+6
A lot of these static symbols are pre-interned.
2019-05-13Rollup merge of #60562 - iliekturtles:proc-macro-missing-docs, r=alexcrichtonMazdak Farrokhzad-1/+6
Add #[doc(hidden)] attribute on compiler generated module. Resolves unavoidable `missing_docs` warning/error on proc-macro crates. Resolves #42008. Changes not yet tested locally, however I wanted to submit first since `rustc` takes forever to compile.
2019-05-13Return a `Symbol` from `name_or_empty` functions.Nicholas Nethercote-2/+2
2019-05-13Remove the equality operation between `Symbol` and strings.Nicholas Nethercote-6/+6
And also the equality between `Path` and strings, because `Path` is made up of `Symbol`s.
2019-05-13Pass a `Symbol` to `check_name`, `emit_feature_err`, and related functions.Nicholas Nethercote-31/+36
2019-05-11Add #[doc(hidden)] attribute on compiler generated proc-macro module.Mike Boutin-1/+6

2019-04-21Introduce `LocalSource` into the AST.David Wood-0/+1
This will be used to keep track of the origin of a local in the AST. In particular, it will be used by `async fn` lowering for the locals in `let <pat>: <ty> = __arg0;` statements.
