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
