Dear Ian, I use as atribute of one of the instructions the following define_insn_reservation: (define_insn_reservation "vmove" 1 "vector_type" "vmove") "c_valu_1|c_vlsu_1")
As you can see vmove has two alternative reservation : c_valu_1 or c_vlsu_1, where c_valu_1 is defined as follows: (define_reservation "c_valu_1" "nothing, r_valu_rp, nothing, nothing, nothing, nothing") and c_vlsu_1: (define_reservation "c_vlsu_1" "nothing, r_vlsu, nothing, nothing, nothing, nothing") Having an RTX after sched2, how can I decide which of the two alternatives (c_valu_1 or c_vlsu_1) the scheduler has selected? thanks for your help! Alex
