;; 0 `sin' operation: operand 0 is the result, operand 1 the parameter,
;;   the mode is MODE_FLOAT
;; 1 `cos' operation: operand 0 is the result, operand 1 the parameter,
;;   the mode is MODE_FLOAT
;; 2 `push multiple' operation: operand 0 is the first register.  Subsequent
;;   registers are in parallel (use...) expressions.
;; 3 A symbol that has been treated properly for pic usage, that is, we
;;   will add the pic_register value to it before trying to dereference it.
;; Note: sin and cos are no-longer used.

;; Attributes

; PROG_MODE attribute is used to determine whether condition codes are
; clobbered by a call insn: they are if in prog32 mode.  This is controlled
; by the -mapcs-{32,26} flag, and possibly the -mcpu=... option.
(define_attr "prog_mode" "prog26,prog32" (const (symbol_ref "arm_prog_mode")))

(define_attr "is_strongarm" "no,yes" (const (symbol_ref "arm_is_strong")))

; Floating Point Unit.  If we only have floating point emulation, then there
; is no point in scheduling the floating point insns.  (Well, for best
; performance we should try and group them together).

; LENGTH of an instruction (in bytes)

; POOL_RANGE is how far away from a constant pool entry that this insn
; can be placed.  If the distance is zero, then this insn will never
; reference the pool.
(define_attr "pool_range" "" (const_int 0))

; An assembler sequence may clobber the condition codes without us knowing
; If such an insn references the pool, then we have no way of knowing how,

; TYPE attribute is used to detect floating point instructions which, if

; If write-buffer scheduling is enabled then it can also be used in the

; Classification of each insn
; normal        any data instruction that doesn't hit memory or fp regs
; mult          a multiply instruction
; block         blockage insn, this blocks all functional units
; float         a floating point arithmetic operation (subject to expansion)
; fdivx         XFmode floating point division
; fdivd         DFmode floating point division
; fdivs         SFmode floating point division
; fmul          Floating point multiply
; ffmul         Fast floating point multiply
; farith        Floating point arithmetic (4 cycle)
; ffarith       Fast floating point arithmetic (2 cycle)
; float_em      a floating point arithmetic operation that is normally emulated
;               even on a machine with an fpa.
; f_load        a floating point load from memory
; f_store       a floating point store to memory
; f_mem_r       a transfer of a floating point register to a real reg via mem
; r_mem_f       the reverse of f_mem_r

; addresses are fully pipelined.  However, a read from memory that is not
; currently in the cache will block until the writes have completed.
; It is normally the case that FCLK and MCLK will be in the ratio 2:1, so
; writes will take 2 FCLK cycles per word, if FCLK and MCLK are asynchronous
; (they aren't allowed to be at present) then there is a startup cost of 1MCLK
; cycle to add as well.
