  [(match_operand:SI 0 "register_operand" "=3D&d")        ;; bool output
   (match_operand:SI 1 "register_operand" "=3D&d")        ;; val output
   (match_operand:SI 2 "nonimmediate_operand" "+Q")     ;; memory
   (match_operand:SI 3 "register_operand" "d")          ;; expected value
   (match_operand:SI 4 "register_operand" "d")          ;; desired value
   (match_operand:SI 5 "const_int_operand" "")          ;; is_weak
   (match_operand:SI 6 "const_int_operand" "")          ;; mod_s
   (match_operand:SI 7 "const_int_operand" "")          ;; mod_f
   (clobber (match_scratch:SI 8 "=3D&d"))]


"d" is:
(define_register_constraint "d" "GR_REGS"
  "A general register.")


So this should work. someone will have to debug this further to see why it =
is
not.

Can someone please test a newer compiler and if it still happens attach the
preprocessed source?=
