| This tool extracts coverage mapping information from an LLVM IR assembly file |
| (`.ll`), and prints it in a more human-readable form that can be used for |
| snapshot tests. |
| |
| The output format is mostly arbitrary, so it's OK to change the output as long |
| as any affected tests are also re-blessed. However, the output should be |
| consistent across different executions on different platforms, so avoid |
| printing any information that is platform-specific or non-deterministic. |
| |
| ## Demangle mode |
| |
| When run as `coverage-dump --demangle`, this tool instead functions as a |
| command-line demangler that can be invoked by `llvm-cov`. |
