| libFuzzer support for QuickJS | ||
| ============================= | ||
|
|
||
| Build QuickJS with libFuzzer support as follows: | ||
|
|
||
| CONFIG_CLANG=y make libfuzzer | ||
|
|
||
| This can be extended with sanitizer support to improve efficacy: | ||
|
|
||
| CONFIG_CLANG=y CONFIG_ASAN=y make libfuzzer | ||
|
|
||
|
|
||
| Currently, there are three fuzzing targets defined: fuzz_eval, fuzz_compile and fuzz_regexp. | ||
| The above build command will produce an executable binary for each of them, which can be | ||
| simply executed as: | ||
|
|
||
| ./fuzz_eval | ||
|
|
||
| or with an initial corpus: | ||
|
|
||
| ./fuzz_compile corpus_dir/ | ||
|
|
||
| or with a predefined dictionary to improve its efficacy: | ||
|
|
||
| ./fuzz_eval -dict fuzz/fuzz.dict | ||
|
|
||
| or with arbitrary CLI arguments provided by libFuzzer (https://llvm.org/docs/LibFuzzer.html). |

How is this dict created? If automated, is it possible to check-in the script that does so?
