2017-07-24Make the macro parser theory description more accuratePiotr Czarnecki-100/+102
2017-07-07Only match a fragment specifier the if it starts with certain tokens.kennytm-4/+70
Fixes #24189. Fixes #26444. Fixes #27832. Fixes #34030. Fixes #35650. Fixes #39964. Fixes the 4th comment in #40569. Fixes the issue blocking #40984.
2017-06-26Simplify `hygiene::Mark` application, andJeffrey Seyfried-15/+9
remove variant `Token::SubstNt` in favor of `quoted::TokenTree::MetaVar`.
2017-06-08Speed up expansion.Mark Simulacrum-17/+23
This reduces duplication, thereby increasing expansion speed.
2017-05-18Add an option to the parser to avoid parsing out of line modulesNick 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.
2017-05-16Rollup merge of #41957 - llogiq:clippy-libsyntax, r=petrochenkovMark Simulacrum-28/+29
Fix some clippy warnings in libsyntax This is mostly removing stray ampersands, needless returns and lifetimes. Basically a lot of small changes.

2017-01-20Rollup merge of #39118 - jseyfried:token_tree_based_parser, r=nrcAlex 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

fragment.
2016-11-12Remove extra level of nesting.Mark-Simulacrum-35/+32
2016-11-12Move next_eis out of main loop to avoid re-allocating and dropping it.Mark-Simulacrum-1/+2
2016-11-12Use SmallVector for eof and bb eis.Mark-Simulacrum-6/+4
2016-11-12Factor out inner current Earley item loop.Mark-Simulacrum-146/+153
Change multiple functions to be non-public. Change nameize to accept an iterator so as to avoid an allocation.
2016-11-12Refactor parse_nt.Mark-Simulacrum-8/+13
2016-11-12Factor out NamedParseResult.Mark-Simulacrum-4/+3
2016-11-12Clean up extraneous &mut.Mark-Simulacrum-1/+1
2016-11-12Refactor to extending from a drain instead of while looping.Mark-Simulacrum-3/+1
2016-11-12Remove unused argument from nameize.Mark-Simulacrum-6/+6
Also makes nameize non-public since it's only locally used.
2016-11-12Cleanup macro_parser::parse, removing a few clones.Mark-Simulacrum-51/+35
2016-11-04Improve `tt`-heavy expansion performance.Jeffrey Seyfried-3/+12

2016-11-03Avoid recontructing the `Parser` in `macro_parser.rs`.Jeffrey Seyfried-21/+16
2016-11-03Reduce the size of `Token` and make it cheaper to clone by refactoringJeffrey Seyfried-7/+6
`Token::Interpolated(Nonterminal)` -> `Token::Interpolated(Rc<Nonterminal>)`.
2016-10-29Move `CrateConfig` from `Crate` to `ParseSess`.Jeffrey Seyfried-7/+2
2016-10-25Don't use `Rc` in `TokenTreeOrTokenTreeVec`.Nicholas Nethercote-3/+3
This avoids 800,000 allocations when compiling html5ever.
2016-10-25Use `SmallVector` for the stack in `macro_parser::parse`.Nicholas Nethercote-6/+4
This avoids 800,000 heap allocations when compiling html5ever.
2016-10-21Replace 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.
2016-10-21Avoid an unnecessary clone in `macro_parser::parse`.Nicholas Nethercote-1/+1
This avoids ~800,000 allocations in html5ever.
2016-10-19Rollup 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
2016-10-17Fix partially consumed tokens in macro matchers.Jeffrey Seyfried-12/+9
2016-10-14Avoid 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.

2016-06-26Rollup merge of #34385 - cgswords:tstream, r=nrcJeffrey Seyfried-4/+5
syntax-[breaking-change] cc #31645 (Only breaking because ast::TokenTree is now tokenstream::TokenTree.) This pull request refactors TokenTrees into their own file as src/libsyntax/tokenstream.rs, moving them out of src/libsyntax/ast.rs, in order to prepare for an accompanying TokenStream implementation (per RFC 1566).
