Regarding performance, I've made a simple coverage with counters and compared it with AsanCoverage. AsanCoverage produces code like this: mov 0xe86cce(%rip),%al test %al,%al je 48b4a0 # to call __sanitizer_cov ... callq 4715b0 <__sanitizer_cov> A simple counter-based thing (which just increments counters and does nothing else useful) produces this: incq 0xe719c6(%rip) The
