explore is slightly better now.
- fixed minor issues in the mutation engine, thanks to @futhewo for
reporting!
- afl-cc:
- large rewrite by @SonicStark which fixes a few corner cases, thanks!
- instrumentation:
- LLVM 18 support, thanks to @devnexen!
- Injection (SQL, LDAP, XSS) feature now available, see
`instrumentation/README.injections.md` how to activate/use/expand.
- compcov/LAF-intel:
- floating point splitting bug fix by @hexcoder
- due a bug in LLVM 17 integer splitting is disabled!
- due a bug in LLVM 17 integer splitting is disabled there!
- when splitting floats was selected, integers were always split as well,
fixed to require AFL_LLVM_LAF_SPLIT_COMPARES as it should
fixed to require AFL_LLVM_LAF_SPLIT_COMPARES or _ALL as it should
