- afl-fuzz:
- added AFL_TARGET_ENV variable to pass extra env vars to the target
(for things like LD_LIBRARY_PATH)
- better map detection, AFL_MAP_SIZE not needed anymore for most cases
- fix map detection, AFL_MAP_SIZE not needed anymore for most cases
- afl-cc:
- fix cmplog rtn (rare crash and not being able to gather ptr data)
- link runtime not to shared libs
- ensure shared libraries are properly built and instrumented
- show correct LLVM PCGUARD NATIVE mode when auto switching to it
and keep fsanitize-coverage-*list=...
- qemu_mode (thanks @realmadsci):
- move AFL_PRELOAD and AFL_USE_QASAN logic inside afl-qemu-trace
- add AFL_QEMU_CUSTOM_BIN
