Configurable instrumentation ratio #67

Open dkasak opened 5 years ago

dkasak commented 5 years ago

Is it possible to change the instrumentation ratio (i.e. the proportion of branches instrumented), such as with AFL_INST_RATIO in afl? This is useful when fuzzing large programs as another way to reduce the large map density problem.

Hi, dkasak,

I did this implementation in https://github.com/AngoraFuzzer/Angora/commit/027975d9208cf5eb1117cd595a341f8f82820c13

I will merge to the master branch soon.
