The reason seems to be with my cmpwi and my beq... they won't branch.

cmpwi r19, r16
beq+ SUBTRACT
cmpwi r19,r17
beq+ ADD

cmpwi = CoMPare Word Immediate.  Are r16 and r17 immediates?  Nope...they're registers.  You wanted cmpw.  Also, watch out for cmplw and cmplwi.  the L means "logical", this is used for *unsigned* comparisons, on numbers that are not interpreted as negative.

802E85C4:  60000000   nop    -> addi r0,r0,r4

r4 comes from the caller.  If you go to the caller's frame, you might be able to modify r4 before it is passed into this function.
