gccrs now supports the rust_debug_fmt macro, enabling the use of GCC’s diagnostic format specifiers within debug diagnostics. This change aims to enhance the quality and consistency of diagnostic messages generated by the Rust frontend. In exchange for this new formatting capability, the compiler enforces stricter checks on diagnostic quality.
