;; UNSPEC Usage:
;; Note: sin and cos are no-longer used.
;; Unspec constants for Neon are defined in neon.md.
;; Unspec enumerators for Neon are defined in neon.md.
(define_constants
[(UNSPEC_SIN 0) ; `sin' operation (MODE_FLOAT):

; operand 0 is the result,
; operand 1 the parameter.
(UNSPEC_PUSH_MULT 2) ; `push multiple' operation:
; operand 0 is the first register,
; subsequent registers are in parallel (use ...)
; expressions.
(UNSPEC_PIC_SYM 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.
(UNSPEC_PIC_BASE 4) ; Add PC and all but the last operand together,
; The last operand is the number of a PIC_LABEL
; that points at the containing instruction.
(UNSPEC_PRLG_STK 5) ; A special barrier that prevents frame accesses
; being scheduled before the stack adjustment insn.
(UNSPEC_PROLOGUE_USE 6) ; As USE insns are not meaningful after reload,
; this unspec is used to prevent the deletion of
; instructions setting registers for EH handling
; and stack frame generation. Operand 0 is the
; register to "use".
(UNSPEC_CHECK_ARCH 7); Set CCs to indicate 26-bit or 32-bit mode.
