Yes this is independent in that sense. But this
illustrates that the guy with the original message has to be careful if he is trying to do
what he wanted - so this is connected as such. May be as a counter example why he
should expect may be subtle problems when he attempts to clear a
LLVMContext at the first place.

I have not looked too deep into llvm to see if your suggestion would be possible or not.
The only naive approach that I quickly checked at that time was that if the context would prune its
own cache entries we would introduce a circular library dependency.
It would be great to have a solution for this.
It's sad that I cannot promise to look into that, I have already done this too often at
different projects creating a too long backlog on my side to be useful with this. Sorry ...

Greetings
