;; The upper 32 fp regs on the v9 can't hold SFmode values.  To deal with this
;; a second register class, EXTRA_FP_REGS, exists for the v9 chip.  The name
;; is a bit of a misnomer as it covers all 64 fp regs.  The corresponding

;;
;; We start with the DEFINE_EXPANDs, then the DEFINE_INSNs to match
