// This test is a mirror of codegen/issue-59352.rs.
// The LLVM inliner doesn't inline `char::method::is_digit()` and so it doesn't recognize this case
// as effectively `if x.is_some() { x.unwrap() } else { 0 }`.
//
// Currently, the MIR optimizer isn't capable of removing the unreachable panic in this test case.
// Once the optimizer can do that, this test case will need to be updated and codegen/issue-59352.rs
// removed.
