2018-10-29Rollup merge of #55384 - nnethercote:better-integer_lit-float_lit, ↵Pietro Albini-4/+19
r=michaelwoerister Avoid unnecessary allocations in `float_lit` and `integer_lit`. This commit avoids an allocation when parsing any float and integer literals that don't involved underscores. This reduces the number of allocations done for the `tuple-stress` benchmark by 10%, reducing its instruction count by just under 1%.

Before parsing argument names and types, try to consume an incorrectly included doc comment or attribute in order to recover and continue parsing the rest of the fn definition.

r=nikomatsakis Fix #54707 - parse_trait_item_ now handles interpolated blocks as function body decls Fix #54707 - parse_trait_item_ now handles interpolated blocks as function body decls Previously parsing trait items only handled opening brace token and semicolon, I added a branch to the match statement that will also handle interpolated blocks.

2018-10-05Rollup merge of #54833 - abonander:issue-54441, r=petrochenkovPietro Albini-12/+11
make `Parser::parse_foreign_item()` return a foreign item or error Fixes `Parser::parse_foreign_item()` to follow the convention of `parse_trait_item()` and `parse_impl_item()` in that it *must* parse an item or return an error, and then the caller is responsible for detecting the closing delimiter. This prevents it from looping endlessly on an unexpected token in `ext/expand.rs` where it was also leaking memory by continually pushing to `Parser::expected_tokens` via `Parser::check_keyword()`. closes #54441 r? @petrochenkov cc @dtolnay

2018-09-27Auto merge of #52319 - tinco:issue_12590, r=pnkfelixbors-5/+12
Track whether module declarations are inline (fixes #12590) To track whether module declarations are inline I added a field `inline: bool` to `ast::Mod`. The main use case is for pretty to know whether it should render the items associated with the module, but perhaps there are use cases for this information to not be forgotten in the AST.
2018-09-23Fixed off-by-one span.David Wood-1/+1
Fixes the off-by-one span issue where closure argument spans were pointing to the token after the argument.
2018-09-22Rollup merge of #54415 - petrochenkov:norollback, r=estebankPietro Albini-36/+26
parser: Tweak function parameter parsing to avoid rollback on succesfull path Since rollback is not perfect and may e.g. leave non-fatal errors after it, we need to make sure compilation fails if it happens. So in particular case of `fn parse_arg_general` we need to parse the "good" `TYPE` first and only then rollback and recover erroneous `PAT: TYPE` if necessary. Found when working on https://github.com/rust-lang/rfcs/pull/2544#issuecomment-423293222. r? @ghost
