URL: https://github.com/llvm/llvm-project/commit/ae41232191ec73b5ee96e5f21df99a42ca25d626 DIFF: https://github.com/llvm/llvm-project/commit/ae41232191ec73b5ee96e5f21df99a42ca25d626.diff LOG: [clang][Interp] Fix Descriptor::getElemQualType() for complex/vectors We handle them like arrays but still need to differentiate between array/vector/complex types when dealing with QualTypes.
