We'd design a subsystem that works for the easy cases and needs more work to support the offset cases. It would not be designed in such a way that it could _never_ support those architectures. It would simply be such that it only permits use by the cases that are known to work. Then those cases could be expanded as time goes on and people work on adding more support. There's tons of stuff that needs to be done to get this upstream. I'd rather not require it to work for every possible architecture from the start. The testing alone would be impossible. Many subsystems start by working for x86 first and then adding support in other architectures later. (Often with that work done by the people who care about those systems and actually have the hardware to test with.) Logan
