While what we're doing here is convenient, it's not architectural, and it would be better to follow GetPSRFromPSTATE pseudocode.Yes, I think that's the best thing to do. We've been skating by on CPSR and SPSR being the same thing and it's just stopped working.
Would you like me to work on this, or is it something the arm maintainers would fix?
