| // This test is a mirror of mir-opt/issues/issue-59352.rs. The LLVM inliner doesn't inline |
| // `char::method::is_digit()` and `char::method::to_digit()`, probably because of their size. |
| // |
| // Currently, the MIR optimizer isn't capable of removing the unreachable panic in this test case. |
| // Once the optimizer can do that, mir-opt/issues/issue-59352.rs will need to be updated and this |
| // test case should be removed as it will become redundant. |
| |
| // mir-opt-level=2 enables inlining and enables LLVM to optimize away the unreachable panic call. |
