OK. Can I do that as incremental patch?

I must say that after some tought, I would preffer the move patch
instead - we have reformating penalties on some loads that I think
renders SSE2 integer support to be unusable and breaks Intel
specification that states what instructions should be used to load
integer data:

(define_insn "movv4si_internal"
  [(set (match_operand:V4SI 0 "nonimmediate_operand" "=x,m")
	(match_operand:V4SI 1 "nonimmediate_operand" "xm,x"))]
  "TARGET_SSE"
  ;; @@@ let's try to use movaps here.
  "movaps\t{%1, %0|%0, %1}"
  [(set_attr "type" "ssemov")
   (set_attr "mode" "V4SF")])

And similar patterns.   Of course I can submit patch to fix these
separately too.
