For some use cases, it would be nice to allow having multiple harnesses compiled into the same target software and selectively enable them at run-time. There are a few ways we can do this:

  • Encode it into n of the magic instruction. This is problematic on some architectures, for example ARM Thumb-2, n <= 12.
  • Encode it into yet another magic register. This is an OK approach but it does further increase the harness code complexity. If enabled with MAGIC_START_SELECT (4) this will be OK. Extended stop harnesses already include a way to communicate a value back to the fuzzer, so only start harnesses need to be extended.
