  1. Ages old (~2014 IIRC) defer implementation for gcc and for clang: https://github.com/google/honggfuzz/blob/c549b4c31815e170d3b...

  3. …it tries to produce an input which matches some form of variable check inside the fuzzed code: https://github.com/google/honggfuzz/blob/1f09e3bfb0785d9b311... register uint8_t v = ((sizeof(Arg1) * 8) - __builtin_popcount(Arg1 ^ Arg2));…

  4. A real world example of use: https://github.com/google/honggfuzz/blob/075756bea8d1f08eb19... I think it's a bit better than ld -b binary ... cause it doesn't depend on the static linker generating symbols, which feels a bit like a…

  7. The clang code requires -fblocks/-lBlocksRuntime too, and I was a bit quicker :) https://github.com/google/honggfuzz/commit/a9db9ddc2e24d157a...

  9. …like to test persistent fuzzing (should be faster due to a few factors), you can try modifying https://github.com/google/honggfuzz/blob/master/examples/lib... - it will probably take creating main() func which will read data in the…

  13. I wonder if this is in any way inspired by this - https://github.com/google/honggfuzz/blob/master/common.h ? I use there defer for both gcc/clang, countof(arr) -> ARRAYSIZE(array) In any case, yeah, going through gcc/clang internals, and…

  14. You can try https://github.com/google/honggfuzz - The basic idea is pretty much the same as with afl-fuzz - maximization of code coverage (more or less). Some old write-up on the technique can be found here:…
