tests: remove uses of Gc. 2014-10-02 05:10:09 +00:00			`use std::rc::Rc;`
rustc: Obsolete the `@` syntax entirely This removes all remnants of `@` pointers from rustc. Additionally, this removes the `GC` structure from the prelude as it seems odd exporting an experimental type in the prelude by default. Closes #14193 [breaking-change] 2014-06-12 02:33:52 +00:00
Update compile fail tests to use usize. 2015-01-08 11:02:42 +00:00			`fn foo(_x: Rc<usize>) {}`
make it illegal to implicitly capture mutable variables this is the final part of #1273 2012-05-07 18:31:57 +00:00
Mostly rote conversion of `proc()` to `move\|\|` (and occasionally `Thunk::new`) 2014-11-26 13:12:18 +00:00			`fn bar<F:FnOnce() + Send>(_: F) { }`
Correct various compile-fail tests. Most of the changes are because we now don't print duplicate errors within one context, so I sometimes had to break functions into two functions. 2014-11-08 01:23:33 +00:00

Remove integer suffixes where the types in compiled code are identical. 2015-03-03 08:42:26 +00:00			`let x = Rc::new(3);`
Keep track of the whole error chain 2014-12-23 09:57:44 +00:00			`bar(move\|\| foo(x));`
pretty: trim paths of unique symbols If a symbol name can only be imported from one place for a type, and as long as it was not glob-imported anywhere in the current crate, we can trim its printed path and print only the name. This has wide implications on error messages with types, for example, shortening `std::vec::Vec` to just `Vec`, as long as there is no other `Vec` importable anywhere. This adds a new '-Z trim-diagnostic-paths=false' option to control this feature. On the good path, with no diagnosis printed, we should try to avoid issuing this query, so we need to prevent trimmed_def_paths query on several cases. This change also relies on a previous commit that differentiates between `Debug` and `Display` on various rustc types, where the latter is trimmed and presented to the user and the former is not. 2020-09-02 07:40:56 +00:00			//~^ ERROR `Rc<usize>` cannot be sent between threads safely
