   @ariadne @cr1901 Are you sure the behavior of jumps in delay slots isn't documented, or at least documented as invalid/undocumented? I don't think it's expected for them to behave as a normal jump, but if I understand right here, it's behaving as an "else" for the conditional jump, right?

     Jumps in delay slots were undefined behavior in mips isa when I was working with it.

     So this is testing the exact implementation of delay slots. Some emulators handle delay slots as instructions before the branch iirc.
