Research direction

Start with the builtin macro declarations listed in rustc_builtin_macros/src/lib.rs at the referenced Rust revision, then compare them with the checked and unchecked entries in this issue. Identify the relevant gccrs compiler entry points for one missing macro and confirm its behavior against the Rust 1.49 libcore list; done means the selected macro is supported and its checklist entry can be updated.
