The concrete issue could be tracked to a copy/paste error in RocM that registers an option explicitly without requirement and can be solved there.

Patch seemed to not apply anymore against 16.x. Fixed that.

Opened the RFC here:

Yes, of course. The problem encoutered is, that loading two libraries via an OpenCL ICD loader [1,2] linking to the same libLLVM triggers the CommandLine error exactly at the revised code lines. I suspect, that the general problem is an abort by libLLVM when loading more than one library linking to any version including the same version. The problem I’m trying to solve, is loading two libraries linking to the same version. This patch obviously does not restrict to loading just the same version, so it has to be extended in that regard.
