some fuzz hacking
Try to start faster:
- remove flags dependency
- print nothing
- strip unused symbols from the binary on Mac (smaller binary)
- only create one fuzz object
- only run one DEF_FUZZ
I am not sure if any of these things mattered, but I thought you may like to look.
Good stuff:
- make nextU() / nextF() work
- drop nextURange() / nextFRange() for now
- add nextB() for a single byte
As you may have guessed, I have figured out how to use afl-fuzz on my laptop.
Syntax to run becomes:
$ afl-fuzz ... out/Release/fuzz <DEF_FUZZ name> @@
