// 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=3 enables inlining and enables LLVM to optimize away the unreachable panic call.
