@ -245,6 +245,16 @@ The fuzzer itself will still be mutating a string of bytes
but before passing this input to the target library it will replace every byte ``b`` with the ``b``-th token.
If there are less than ``b`` tokens, a space will be added instead.
AFL compatibility
-----------------
LibFuzzer can be used in parallel with AFL_ on the same test corpus.
Both fuzzers expect the test corpus to reside in a directory, one file per input.
You can run both fuzzers on the same corpus in parallel::
./afl-fuzz -i testcase_dir -o findings_dir /path/to/program -r @@
./llvm-fuzz testcase_dir findings_dir # Will write new tests to testcase_dir
Periodically restart both fuzzers so that they can use each other's findings.
