add tests for fn pointers 2016-06-13 05:29:01 -05:00			`fn f() {}`

don't use `#[miri_run]` anymore, but execute the `main` function 2016-06-13 07:27:05 -05:00			`fn main() {`
			`let x: i32 = unsafe {`
port some tests to check the new error format 2018-07-15 05:00:02 -05:00			`std::mem::transmute::<fn(), const i32>(f) //~ ERROR constant evaluation error: tried to dereference a function pointer`
