;; The MMX and 3dNOW! patterns are in the same file because they use
;; the same register file, and 3dNOW! adds a number of extensions to
;; the base integer MMX isa.

;; Note!  Except for the basic move instructions, *all* of these
;; patterns are outside the normal optabs namespace.  This is because
;; use of these registers requires the insertion of emms or femms
;; instructions to return to normal fpu mode.  The compiler doesn't
;; know how to do that itself, which means it's up to the user.  Which
;; means that we should never use any of these patterns except at the
;; direction of the user via a builtin.
