Zig: a system language which prioritizes optimality, safety, and readability

It's lowlevel, that's why there's so much spec. And much of it is just defining that behaviour is implementation defined.

And as I said, it's as lowlevel as an HLL can be.

I wish we could check the carry flag. You could totally write a C library for that, I bet, by mixing in some asm, and using conditional compilation. Language extension!

GCC since 5.0 and Clang since longer ago than that support (the same) set of builtin functions to check carry and overflow bits:
