Update compile fail tests to use isize. 2015-01-08 04:54:35 -06:00			`fn f(a: isize, a: isize) {}`
librustc: Forbid duplicate name bindings in the same parameter or type parameter list. This breaks code like: fn f(a: int, a: int) { ... } fn g<T,T>(a: T) { ... } Change this code to not use the same name for a parameter. For example: fn f(a: int, b: int) { ... } fn g<T,U>(a: T) { ... } Code like this is not affected, since `_` is not an identifier: fn f(_: int, _: int) { ... } // OK Closes #17568.
