| LL| |The `PartialOrd` derived by `Version` happened to generate a MIR that generated coverage | |
| LL| |without a code region associated with any `Counter`. Code regions were associated with at least | |
| LL| |one expression, which is allowed, but the `function_source_hash` was only passed to the codegen | |
| LL| |(coverage mapgen) phase from a `Counter`s code region. A new method was added to pass the | |
| LL| |`function_source_hash` without a code region, if necessary. | |
