; Check for the immediate offset.  It must be a multiple of 8.
; CHECK: dcfetch({{.*}}+#8)
; In 6.2 (which supports v4+ only), we generate indexed dcfetch in all cases
; (unlike in 6.1, which supported v2, where dcfetch did not allow an immediate
; offset).
; For expression %2, where the offset is +9, the offset on dcfetch should be
; a multiple of 8, and the offset of 0 is most likely (although not the only
; possible one).  Check for #0 anyways, if the test fails with a false
; positive, the second check can be eliminated, or rewritten, and in the
; meantime it can help catch real problems.
