llvm dev - Nov 2021 - getOrInsertFunction issue

Dear community

I'm working on a compiler for a in-house DSP developped with LLVM 8.0.
Now I'm trying to migrate the LLVM base to the latest one (LLVM-13), but I
proceed by steps and first I migrate to LLVM-9.0


In my code, I use the "getOrInsertFunction" method which crashes on
LLVM9.0:

- first call ('insert') -> ok

- second call on an existing funcion ('get') -> the function exists
but it seems that the Context environment is lost for the FunctionType variable
(getContext is empty)


I checked that after the first call of 'getOrInsertFunction', the
context is correct.


Has anyone faced this issue ? Is it resolved in a higher version of LLVM ?

Thank for your help !

Make sure that `getOrInsertFunction` does indeed return a function and not
say a constexpr bitcast (which could happen if type of the function is
different from what was used for the initial insert)
