;; {{{ Scatter / Gather

;; GCN does not have an instruction for loading a vector from contiguous
;; memory so *all* loads and stores are eventually converted to scatter
;; or gather.
;;
;; GCC does not permit MEM to hold vectors of addresses, so we must use an
;; unspec.  The unspec formats are as follows:
;;
;;     (unspec:V??
;;	 [(<address expression>)
;;	  (<addr_space_t>)
;;	  (<use_glc>)
;;	  (mem:BLK (scratch))]
;;	 UNSPEC_GATHER)
;;
;;     (unspec:BLK
;;	  [(<address expression>)
;;	   (<source register>)
;;	   (<addr_space_t>)
;;	   (<use_glc>)
;;	   (<exec>)]
;;	  UNSPEC_SCATTER)
;;
;; - Loads are expected to be wrapped in a vec_merge, so do not need <exec>.
;; - The mem:BLK does not contain any real information, but indicates that an
;;   unknown memory read is taking place.  Stores are expected to use a similar
;;   mem:BLK outside the unspec.
;; - The address space and glc (volatile) fields are there to replace the
;;   fields normally found in a MEM.
;; - Multiple forms of address expression are supported, below.
;;
;; TODO: implement combined gather and zero_extend, but only for -msram-ecc=on
