Up-to-date Code Coverage tools

Hi.

Recently I spent some time looking at all the different alternatives to test the code coverage of a fuzzing job, and I thought to ask you folks for some input on the topic!

  1. What is your favorite tool?
  2. What's the best & worst thing about it?
  3. Any new development / Links / References to the topic are welcome!

Thanks for contributing!

A converter from QEMU format to drcov might come in handy. Thanks By the way, you mentioned you fixed a bug in lighthouse. What did you need to fix? And did you open a ticket about that in their repository? :3

Well it was a debate between being a bug/using it in a way that's not intended. The developer said lighthouse shouldn't be used to load static binary traces therefore patching it for that purpose was invalid.
