2017-08-30	Make fields of `Span` private	Vadim Petrochenkov	-3/+4

2017-08-21	Auto merge of #43540 - petrochenkov:pathrelax, r=nikomatsakis	bors	-3/+1
	syntax: Relax path grammar TLDR: Accept the disambiguator `::` in "type" paths (`Type::<Args>`), accept the disambiguator `::` before parenthesized generic arguments (`Fn::(Args)`). The "turbofish" disambiguator `::<>` in expression paths is a necessary evil required for path parsing to be both simple and to give reasonable results. Since paths in expressions usually refer to values (but not necessarily, e.g. `Struct::<u8> { field: 0 }` is disambiguated, but refers to a type), people often consider `::<>` to be inherent to values, and not expressions and want to write disambiguated paths for values even in contexts where disambiguation is not strictly necessary, for example when a path is passed to a macro `m!(Vec::<i32>::new)`. The problem is that currently, if the disambiguator is not required, then it's prohibited. This results in confusion - see https://github.com/rust-lang/rust/issues/41740, https://internals.rust-lang.org/t/macro-path-uses-novel-syntax/5561. This PR makes the disambiguator optional instead of prohibited in contexts where it's not strictly required, so people can pass paths to macros in whatever form they consider natural (e.g. disambiguated form for value paths). This PR also accepts the disambiguator in paths with parenthesized arguments (`Fn::(Args)`) for consistency and to simplify testing of stuff like https://github.com/rust-lang/rust/pull/41856#issuecomment-301219194.

2017-05-18	Add an option to the parser to avoid parsing out of line modules	Nick Cameron	-2/+6
	This is useful if parsing from stdin or a String and don't want to try and read in a module from another file. Instead we just leave a stub in the AST.

2017-01-20	Rollup merge of #39118 - jseyfried:token_tree_based_parser, r=nrc	Alex Crichton	-20/+4
	Refactor the parser to consume token trees This is groundwork for efficiently parsing attribute proc macro invocations, bang macro invocations, and `TokenStream`-based attributes and fragment matchers. This improves parsing performance by 8-15% and expansion performance by 0-5% on a sampling of the compiler's crates. r? @nrc

2016-10-25	Use `SmallVector` for the stack in `macro_parser::parse`.	Nicholas Nethercote	-6/+4
	This avoids 800,000 heap allocations when compiling html5ever.
2016-10-21	Replace the `String` in `ParseResult::Failure` with `Token`.	Nicholas Nethercote	-6/+13
	This lets us delay creation of failure messages until they are needed, which avoids ~1.6M allocations in html5ever.
2016-10-21	Avoid an unnecessary clone in `macro_parser::parse`.	Nicholas Nethercote	-1/+1
	This avoids ~800,000 allocations in html5ever.
2016-10-19	Rollup merge of #37208 - jseyfried:fix_partially_consumed_tokens_in_macros, ↵	Eduard-Mihai Burtescu	-12/+9
	r=nrc macros: fix partially consumed tokens in macro matchers Fixes #37175. This PR also avoids re-transcribing the tokens consumed by a matcher (and cloning the `TtReader` once per matcher), which improves expansion performance of the test case from #34630 by ~8%. r? @nrc
2016-10-17	Fix partially consumed tokens in macro matchers.	Jeffrey Seyfried	-12/+9

2016-10-14	Avoid many CrateConfig clones.	Nicholas Nethercote	-1/+1
	This commit changes `ExtCtx::cfg()` so it returns a `CrateConfig` reference instead of a clone. As a result, it also changes all of the `cfg()` callsites to explicitly clone... except one, because the commit also changes `macro_parser::parse()` to take `&CrateConfig`. This is good, because that function can be hot, and `CrateConfig` is expensive to clone. This change almost halves the number of heap allocations done by rustc for `html5ever` in rustc-benchmarks suite, which makes compilation 1.20x faster.
