Improve wording of static_mut_ref Rename `static_mut_ref` lint to `static_mut_refs`. 2024-02-17 19:01:56 +00:00			`#![allow(static_mut_refs)]`
allow static_mut_ref in some tests that specifically test mutable statics 2024-02-12 14:14:58 +00:00
Update compile fail tests to use usize. 2015-01-08 11:02:42 +00:00			`const C1: &'static mut [usize] = &mut [];`
Permit mutable references in all const contexts 2021-01-03 18:46:20 +00:00			`//~^ ERROR: mutable references are not allowed`
test: Convert statics to constants Additionally, add lots of tests for new functionality around statics and `static mut`. 2014-10-07 04:16:35 +00:00
Update compile fail tests to use usize. 2015-01-08 11:02:42 +00:00			`static mut S: usize = 3;`
test: adjust for the move to MIR-based const checking. 2016-05-02 22:57:35 +00:00			`const C2: &'static mut usize = unsafe { &mut S };`
unstably allow constants to refer to statics and read from immutable statics 2024-01-05 11:18:11 +00:00			`//~^ ERROR: referencing statics in constants`
