2016-05-24Avoid iterating two times over the list of LHSes.Leo Testard-5/+4
2016-05-24Make sure that macros that didn't pass LHS checking are not expanded.Leo Testard-41/+56
This avoids duplicate errors for things like invalid fragment specifiers, or parsing errors for ambiguous macros. Fixes #29231.

syntax: Merge PathParsingMode::NoTypesAllowed and PathParsingMode::ImportPrefix syntax: Rename PathParsingMode and its variants to better express their purpose syntax: Remove obsolete error message about 'self lifetime syntax: Remove ALLOW_MODULE_PATHS workaround syntax/resolve: Adjust some error messages resolve: Compare unhygienic (not renamed) names with keywords::Invalid, invalid identifiers may appear to be valid after renaming

2016-03-22try! -> ?Jorge Aparicio-2/+2

2016-02-18Remove unnecessary explicit lifetime bounds.Corey Farwell-11/+11
These explicit lifetimes can be ommitted because of lifetime elision rules. Instances were found using rust-clippy.

See RFC amendment 1384 and tracking issue 30450: https://github.com/rust-lang/rfcs/pull/1384 https://github.com/rust-lang/rust/issues/30450 Moved old check_matcher code into check_matcher_old combined the two checks to enable a warning cycle (where we will continue to error if the two checks agree to reject, accept if the new check says accept, and warn if the old check accepts but the new check rejects).
2016-01-06Auto merge of #30654 - nrc:panictry, r=brsonbors-4/+4
The motivation (other than removing boilerplate) is that this is a baby step towards a parser with error recovery. [breaking-change] if you use any of the changed functions, you'll need to remove a try! or panictry!
