// run-pass

// This tests the allocating algo branch of the
// inherent impls overlap checker.
// This branch was added by PR:
// https://github.com/rust-lang/rust/pull/78317
// In this test, we repeat many impl blocks
// to trigger the allocating branch.
#![allow(unused)]
extern crate repeat;
// Simple case where each impl block is distinct
struct Foo {}
repeat::repeat_with_idents!(impl Foo { fn IDENT() {} });
// There are overlapping impl blocks but due to generics,
// they may overlap.

struct A;
struct B;
repeat::repeat_with_idents!(impl Bar<A> { fn IDENT() {} });
impl Bar<A> { fn foo() {} }
