| // This program tries to fuzz the demangler shipped as part of the swift |
| // compiler. |
| // For this to work you need to pass --enable-sanitizer-coverage to build-script |
| // otherwise the fuzzer doesn't have coverage information to make progress |
| // (making the whole fuzzing operation really ineffective). |
| // It is recommended to use the tool together with another sanitizer to expose |
| // more bugs (asan, lsan, etc...) |
