blocks:

  • SR-12540 [C++] Import class template instantiations

relates to:

  • SR-12471 [C++] Populate value witness tables for C++ types

Issue Description:

IRGen should lower SIL instructions that load, store, move, assign C++ types by correctly invoking the appropriate C++ special members.

This bug might be fixed automatically when https://bugs.swift.org/browse/SR-12471 is fixed. Even in that case, we should write tests that check lowering of SIL instructions.
