Andrea, Regardless of whether the big-endian bugs are solved with this, could you please try to give us an idea of how this change could affect the native code produced by Emacs, and whether it could destabilize Emacs with natively-compiled Lisp code to any significant degree? We intend to start pretest of Emacs 28.1 soon, and I'm a bit bothered by such low-level changes, because they could invalidate all the good experience and debugging we accumulated since the native-comp branch landed on master. If this change is potentially destabilizing, we may need to reassess our release schedule, so as to give this code more time to mature. Thanks.
