This is needed to support fortran assumed rank arrays which have runtime rank. Summary: Fortran assumed rank arrays have dynamic rank. DWARF TAG DW_TAG_generic_subrange is needed to support that. Testing: unit test cases added (hand-written) check llvm check debug-info Reviewed By: aprantl Differential Revision: https://reviews.llvm.org/D89218
