@dougall @marcan So to correlate I think you first need to decode the instruction, figure out its possible range, then see if your watchpoint could be in it. If you have multiple watchpoints that match, tough luck I guess? Honestly not sure what you are supposed to do here…

@dougall @marcan Anyways it’s probably needless to say that nobody really has answers here or bothers to do anything beyond the basics so it’s broken in all the debuggers that I know of. For example I found this when double checking something just now: https://discourse.llvm.org/t/aarch64-watchpoints-reported-address-outside-watched-range-adopting-mask-style-watchpoints/67660
