Hi all, I'd like to propose an ODR checker feature for Clang and LLD. The feature would be similar to gold's --detect-odr-violations feature, but better: we can rely on integration with clang to avoid relying on debug info and to perform more precise matching. The basic idea is that we use clang's ability to create ODR hashes for declarations. ODR hashes are computed using all
