Hi All : It's possible to define multi delay slots for branch insns by using define_delay, and different slot should satisfy its own attribute test "delay-n".
Here comes question, in function "fill_simple_delay_slots", seems it only uses slots_filled to record how many slots needs to fill, and puts slot insns already found in delay_list. I can't find any codes keeping the information about which insn in delay_list belongs to which slot(defined in "define_delay"). So, how does gcc make sure that insns in delay_list go into right delay slot? Thanks in advance. -- Best Regards.
