I hope the scheduler doesn't attempt to swap sp += 24 with flags setter
because of the sp += 16 vs. flags setter dependency and sp += 24 vs. sp +=
16 dependency, but I feel kind of uneasy with find_inc assuming the recorded
dependency is the one for the mem_reg0, when in this case the dependency is
there for completely different register.


Let me think about that for a while. Thanks for debugging the cache problem.
