   Is there a reason why clang-11/LTO should not be available when now the minimum clang version required by this project is clang 16?

   Anecdotally, I’ve had at least one situation where afl-clang-lto wouldn’t build but I forget which clang version I was on.

   Same here. From the build summary: LLVM LTO mode could not be built, it is optional, if you want it, please install LLVM 11-14. More information at instrumentation/README.lto.md on how to build it
