Am I correct in my understanding that you can't put a branch instruction in the delay slot of a branch instruction?
Semantically, the HW I'm looking at annuls the branch in the delay slot if the first branch is taken, but any other instructions are not annulled; but it appears that there's no way to describe this in the define_delay() and it looks to me like the delay-slot for the instruction in the delay slot won't get filled properly either. e.g. cmpi $r1,0 jeq $1 jlt $2 jmp $3 nop would be a 3-way branch on zero, neg or (by elimination) positive values with the indented instructions being in a branch delay slot.
