At a high level, this is correct: https://github.com/Rust-GCC/gccrs/wiki/Frequently-Asked-Questions#what-is-the-plan-for-inconsistencies-in-behaviour https://github.com/Rust-GCC/gccrs/wiki/Frequently-Asked-Ques... > If gccrs interprets a program differently from rustc, this is considered a bug. I don't believe they are only reading the frontend, but using the reference first, then looking to the implementation second, and asking a lot of questions along the way.
