-You can pass args to the fuzzer process using args=
-
-make args=-max_len=4000 run_llvm_tls_client
-
-The fuzzer entry point assumes no more than 4K of input. The base
-libFuzzer default max len is 64 bytes, the makefile sets it to 140 as
-default.
-
-Use
-
-make cmin_redc_p384
-
-to run afl-cmin to minimize and merge the LLVM and AFL outputs back to
-the corpus directory.
