reject macros with empty repetitions Fixes #5067 by checking the lhs of `macro_rules!` for repetitions which could match an empty token tree.

Miscellaneous low priority cleanup in `libsyntax`.
2016-06-26Rollup merge of #34385 - cgswords:tstream, r=nrcJeffrey Seyfried-7/+9
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).
2016-06-25Rollup merge of #34403 - jonathandturner:move_liberror, r=alexcrichtonJeffrey Seyfried-1/+1
This PR refactors the 'errors' part of libsyntax into its own crate (librustc_errors). This is the first part of a few refactorings to simplify error reporting and potentially support more output formats (like a standardized JSON output and possibly an --explain mode that can work with the user's code), though this PR stands on its own and doesn't assume further changes. As part of separating out the errors crate, I have also refactored the code position portion of codemap into its own crate (libsyntax_pos). While it's helpful to have the common code positions in a separate crate for the new errors crate, this may also enable further simplifications in the future.

2016-06-07Auto merge of #33982 - LeoTestard:remove-check-matcher-old, r=pnkfelixbors-233/+18
Remove the old FOLLOW checking (aka `check_matcher_old`). It was supposed to be removed at the next release cycle but is still in the tree since like 6 months. Potential breaking change, since some cases (such as #25658) will change from a warning to an error. But the warning stating that it will be a hard error in the next release has been there for 6 months now. I think it's safe to break this code. ^_^

2016-05-26Reject a LHS formed of a single sequence TT during `macro_rules!` checking.Leo Testard-9/+4
This was already rejected during expansion. Encountering malformed LHS or RHS during expansion is now considered a bug.
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-33/+53
This avoids duplicate errors for things like invalid fragment specifiers, or parsing errors for ambiguous macros. Fixes #29231.

2016-01-07macro_rules: proper FIRST/FOLLOW computations for checking macro_rules validity.Felix S. Klock II-16/+500
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-2/+2
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!
