;; Don't have reload use general registers to load a constant.  It is
;; less efficient than loading the constant into an FP register, since
;; it will probably be used there.

;; The move constraints are ordered to prefer floating point registers before
;; general purpose registers to avoid doing a store and a load to get the value
;; into a floating point register when it is needed for a floating point
;; operation.  Prefer traditional floating point registers over VSX registers,
;; since the D-form version of the memory instructions does not need a GPR for
;; reloading.  ISA 3.0 (power9) adds D-form addressing for scalars to Altivec
;; registers.

;; If we have FPR registers, rs6000_emit_move has moved all constants to memory,
;; except for 0.0 which can be created on VSX with an xor instruction.

;; Power8 fusion support for fusing an addis instruction with a D-form load of
;; a GPR.  The addis instruction must be adjacent to the load, and use the same
;; register that is being loaded.  The fused ops must be physically adjacent.

;; There are two parts to addis fusion.  The support for fused TOCs occur
;; before register allocation, and is meant to reduce the lifetime for the
;; tempoary register that holds the ADDIS result.  On Power8 GPR loads, we try
;; to use the register that is being load.  The peephole2 then gathers any
;; other fused possibilities that it can find after register allocation.  If
;; power9 fusion is selected, we also fuse floating point loads/stores.

;; Fused TOC support: Replace simple GPR loads with a fused form.  This is done
;; before register allocation, so that we can avoid allocating a temporary base
;; register that won't be used, and that we try to load into base registers,
;; and not register 0.  If we can't get a fused GPR load, generate a P9 fusion
;; (addis followed by load) even on power8.
