As someone who cross compiles C++ to arm (and others) as part of my $dayjob, I sincerely don't understand this comment. I would like to, as maybe there's something I misunderstand.

Ninja edit: I guess you're suggesting that some parts are in hand rolled x86 assembly, not just pure C++ that would be output as the cross compiler target architecture?

There's usually a million assumptions that are technically undefined behaviour but work, and immediately break if you try to cross-compile by just changing the target system in CMake or w/e.

I could see that if it were being compiled against another libc as well. It's true my experience is with a codebase that has forever been cross compiled. Just altering the output architecture I guess I just haven't seen be an issue. Aarch64 hasn't ever given me an "immediately break" scenario. If it compiles, it works. Ymmv though. Computers are complex.
