Add `// run-pass` annotations to all the tests under `ui/run-pass/`. (I may have accidentally added it to some auxilliary crates as well; my emacs-macro-based methodology was pretty crude.) 2018-08-30 12:18:55 +00:00			`// run-pass`
Modernize macro_rules! invocations macro_rules! is like an item that defines a macro. Other items don't have a trailing semicolon, or use a paren-delimited body. If there's an argument for matching the invocation syntax, e.g. parentheses for an expr macro, then I think that applies more strongly to the inner delimiters on the LHS, wrapping the individual argument patterns. 2015-01-02 22:44:21 +00:00			`macro_rules! third {`

Changed most vec! invocations to use square braces 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. 2016-10-29 21:54:04 +00:00			`let x = vec![10_usize,11_usize,12_usize,13_usize];`
