Updated the most glaring instances of weak tests w.r.t. NLL that came from #53196. See also the bulletpoint list on #53351. 2018-08-14 23:16:05 +00:00

handle moves in let initializers and allow moves from unsafe ptrs Related to issue #2657, but this is not a complete fix. 2012-06-21 03:08:25 +00:00			`fn main() {`

librustc: Remove the fallback to `int` for integers and `f64` for floating point numbers for real. This will break code that looks like: let mut x = 0; while ... { x += 1; } println!("{}", x); Change that code to: let mut x = 0i; while ... { x += 1; } println!("{}", x); Closes #15201.
