Sure, but there's no reason for gas to not accept what MASM would. You also don't really make clear why you think this is an issue, and hence why it should be changed in gcc. > The `foo[rip]` part is also invalid but it's a common issue for all > addressing operands for x86_64, not specifically about jmp. Why's that invalid? foo[eax] and [foo+eax] have always been equivalent in MASM, and I see no reason why this shouldn't hold for rip-relative addressing as well.
