@strongcourage had the idea of integrating https://github.com/aflgo/aflgo into afl++

My opinion - just putting down my thoughts:

its an interesting feature for sure.

we partially can achieve something like that with the whitelist feature in llvm_mode, and @hexcoder- has thought about rewriting the whitelist feature code to allow to match on function names.
But it does not reach the fine-grained targeting that aflgo has.

usually if you fix something you have a crashing test case, only if you dont have one, you would need aflgo.

the overall steps to finally run aflgo are quite some and its complicated to get there (compared to normal llvm_mode compiling)

looking at the specific changes: mirrorer/afl@master...aflgo:master
I can see that the shm mapsize is different to normal, and the llvm_mode has been rewritten a lot.
So: I don't think the two projects are actually compatible to have in one tool - or only with complex code changes

TLDR: interesting feature, however very special case, and I doubt it can be easily integrated. However I only had a quick look
