Hi Vlad,
There is not enough information to say what is wrong. It

Hi,
I'm trying to get the DFA scheduler in GCC 4.0.0 to schedule loads and
stores, but I can only get it to work for loads. I have an automaton defined
as follows:
(define_automaton "cpu")
(define_cpu_unit "x" "cpu")
(define_cpu_unit "m" "cpu")
(define_insn_reservation "arith" 1

Stores don't really have a 'result', why have you set the
cycle count

Jon,
(define_insn_reservation "arith" 1 (eq_attr "type" "arith") "x")
(define_insn_reservation "loads" 2 (eq_attr "type" "load") "x,m")
(define_insn_reservation "stores" 3 (eq_attr "type" "store") "x,m*2")
Stores don't really have a 'result', why have you set the cycle
count to 3? Shouldn't it be
