Implement partial instrumentation #50

brunoproduit commented 12 months ago

AFL has the possibility to configure partial instrumentation. This could help the fuzzer concentrate on the important part as well as have a coverage that is only on what we find interesting.

As #[no_coverage] in rustc is __attribute__((no_sanitize("coverage"))) it should allow us to support disabling instrumentation on a per function basis, thus allowing partial instrumentation

This is now implemented with bruno's afl.rs cmplog feature, via AFL_LLVM_ALLOWLIST/AFL_LLVM_DENYLIST but this does not work for honggfuzz. I think we can close this?

I guess we need to set the cmplog feature to afl.rs for this to work?
