Description
auto-reduced (treereduce-rust):
struct Foo(usize);
const fn get(x: Foo) -> usize {
x.0
}
const X: Foo = Foo(22);
const Z: usize = get(*&X);
original:
// Regression test for #38520. Check that moves of `Foo` are not
// permitted as `Foo` is not copy (even in a static/const
//simple test to make sure that calls to `Pointer::fmt` aren't double counted
struct Foo(usize);
const fn get(x: Foo) -> usize {
x.0
}
const X: Foo = Foo(22);
static Y: usize = get(*&X); //~ ERROR [E0507]
const Z: usize = get(*&X); //~ ERROR [E0507]
fn main() {
}
