a1xndr added a comment to D65672: [compiler-rt] Expose fuzzer coverage bitmaps to the target.

Not a libfuzzer person, but i wonder if this lifts the veil from internal implementation detail too much?

Ping. This has been a useful feature for fuzzing QEMU virtual devices. It has some overhead due to the memcpy, but there are ways to avoid this overhead, by adding a user-modifiable counters pointer, or possibly re-mapping existing counter regions as shared memory.
