# Creates fuzzer builds of various kinds
|
||
|
|
# - reproduce mode (no fuzzing, just enables replaying data through the fuzzers)
|
||
|
|
# - oss-fuzz emulated mode (makes sure a simulated invocation by oss-fuzz works)
|
||
|
|
# - libFuzzer build (you will need clang)
|
||
|
|
# - afl build (you will need afl)
