Research direction
Start by reading the linked rustc_codegen_gcc fix commit (02198d8458b9894c2450d5ea0a4e2e979dc56b84) and the surrounding issue discussion to identify the affected case and entry point. Reproduce that case and compare variable creation before and after the fix; done means the unnecessary variables are no longer created and the relevant regression coverage passes.
