10 // that exports LLVMFuzzerTestOneInput() and possibly LLVMFuzzerInitialize())
11 // instead of libFuzzer. This main() function will not perform any fuzzing
12 // but will simply feed all input files one by one to the fuzz target.

14 // Use this file to provide reproducers for bugs when linking against libFuzzer
15 // or other fuzzing engine is undesirable.
