The MIPS R4000, part 9: Stupid branch delay slot tricks – The Old... A delay slot is created by a branch executing directly before it, what is in the delay slot never knows that it’s a delay slot. If you jump into what is a branch delay slot, then the preceding branch has it’s delay slot elsewhere. With MIPS it helps to think of the pipeline, so a load or a branch doesn’t update the registers directly. The MIPS R4000, part 8: Control transfer – The Old New Thing

In the octeon case, we modify k1 in the branch delay slot, but we never need k0 again, so the new load is not needed, but since k1 is modified, if we do the load, we load from a garbage location and then get a nested TLB Refill, which is seen in userspace as either SIGBUS or SIGSEGV (depending on the garbage).
