2017-05-16Rollup merge of #41957 - llogiq:clippy-libsyntax, r=petrochenkovMark Simulacrum-7/+8
Fix some clippy warnings in libsyntax This is mostly removing stray ampersands, needless returns and lifetimes. Basically a lot of small changes.

data_structures::SmallVec.
2016-11-10syntax: don't fake a block around closures' bodies during parsing.Eduard Burtescu-2/+2
2016-10-31Changed most vec! invocations to use square bracesiirelu-3/+3
Most of the Rust community agrees that the vec! macro is clearer when called using square brackets [] instead of regular brackets (). Most of these ocurrences are from before macros allowed using different types of brackets. There is one left unchanged in a pretty-print test, as the pretty printer still wants it to have regular brackets.
2016-10-29Move `CrateConfig` from `Crate` to `ParseSess`.Jeffrey Seyfried-4/+1
2016-10-25Use `SmallVector` for `TtReader::stack`.Nicholas Nethercote-10/+40
This avoids 800,000 heap allocations when compiling html5ever. It requires tweaking `SmallVector` a little.

Miscellaneous low priority cleanup in `libsyntax`.
2016-06-26Rollup merge of #34385 - cgswords:tstream, r=nrcJeffrey Seyfried-1/+2
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).
2016-06-23Move errors from libsyntax to its own crateJonathan Turner-1/+1
2016-06-21Refactored tokentrees into their own files in preparation for tokenstreams. ↵cgswords-1/+2
Modified tests to point to the new file now.

2016-06-16Auto merge of #34187 - luser:extern-crate-abspaths, r=michaelwoeristerbors-1/+1
Add an abs_path member to FileMap, use it when writing debug info. Fixes #34179. When items are inlined from extern crates, the filename in the debug info is taken from the FileMap that's serialized in the rlib metadata. Currently this is just FileMap.name, which is whatever path is passed to rustc. Since libcore and libstd are built by invoking rustc with relative paths, they wind up with relative paths in the rlib, and when linked into a binary the debug info uses relative paths for the names, but since the compilation directory for the final binary, tools trying to read source filenames will wind up with bad paths. We noticed this in Firefox with source filenames from libcore/libstd having bad paths. This change stores an absolute path in FileMap.abs_path, and uses that if available for writing debug info. This is not going to magically make debuggers able to find the source, but it will at least provide sensible paths.

Revert a change in the scope of macros imported from crates to fix a regression Fixes #34212. The regression was caused by #34032, which changed the scope of macros imported from extern crates to match the scope of macros imported from modules. r? @nrc

2016-06-15prefer `if let` to match with `None => ()` arm in some placesZack M. Davis-6/+4
Casual grepping revealed some places in the codebase (some of which antedated `if let`'s December 2014 stabilization in c200ae5a) where we were using a match with a `None => ()` arm where (in the present author's opinion) an `if let` conditional would be more readable. (Other places where matching to the unit value did seem to better express the intent were left alone.) It's likely that we don't care about making such trivial, non-functional, sheerly æsthetic changes. But if we do, this is a patch.

2016-01-16libsyntax: accept only whitespace with the PATTERN_WHITE_SPACE propertyKevin Butler-20/+19
This aligns with unicode recommendations and should be stable for all future unicode releases. See http://unicode.org/reports/tr31/#R3. This renames `libsyntax::lexer::is_whitespace` to `is_pattern_whitespace` so potentially breaks users of libsyntax.
