--- Comment #2 from ktkachov at gcc dot gnu.org ---
Sorry, I was doing this on top of the patch posted at
https://gcc.gnu.org/ml/gcc-patches/2015-11/msg00686.html
The subreg_highpart_operator predicate is defined as:
(define_special_predicate "subreg_highpart_operator"
(and (match_code "subreg")
(match_test "GET_MODE_SIZE (mode)
< GET_MODE_SIZE (GET_MODE (SUBREG_REG (op)))
&& SUBREG_BYTE (op)
== subreg_highpart_offset (mode,
GET_MODE (SUBREG_REG (op)))")))
