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`
Add `#![allow(..)]` as necessary to get re-migrated run-pass tests compiling with clean stderr again. Most were added mechanically. 2018-09-25 21:51:35 +00:00			`#![allow(path_statements)]`
rustdoc: Replace no-pretty-expanded with pretty-expanded Now that features must be declared expanded source often does not compile. This adds 'pretty-expanded' to a bunch of test cases that still work. 2015-03-22 20:13:15 +00:00			`// pretty-expanded FIXME #23616`

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! inner {`
			`($e:pat ) => ($e)`
			`}`
added unit and standalone test for 15221, extra debugging output 2014-06-27 20:10:47 +00:00
