--- Comment #3 from Georg-Johann Lay <gjl at gcc dot gnu.org> ---
This change is at least incomplete: it does not handle CONST. To see this
change the test case to
returnValue.response = response + 1;
Who is generating these SUBREGs? If it's in a push insn, we should handle that
case in the push insn/expander so that these SUBREGs won't be generated in the
first place.
