I think this patch fixes the problem:

;; Microblaze delay slot description
---- CUT ----
The delay slot description is right below bswaphi2 definition even:
(define_delay (eq_attr "type" "branch,call,jump")
[(and (eq_attr "type"
"!branch,call,jump,icmp,multi,no_delay_arith,no_delay_load,no_delay_store,no_delay_imul,no_delay_move,darith")
(ior (not (match_test "microblaze_no_unsafe_delay"))
(eq_attr "type" "!fadd,frsub,fmul,fdiv,fcmp,store,load")
))
(nil) (nil)])
Or multi could be used instead of no_delay_arith.
