With some recent patches from @StephenTozer , some of those locations can now be described with DBG_VALUE_LIST instructions. If I understand this patch correctly, for WebAssembly those DBG_VALUE_LIST instructions transition back to being "DBG_VALUE $noreg". There should be no regression in variable location coverage: instead, WebAssembly does not yet benefit from the additional locations now being recovered.

Great, thanks for the clarification.
