    c++: coroutines and return in registers [PR118874]

    Because coroutines insert a call to the resumer between the initialization
    of the return value and the actual return to the caller, we need to
    duplicate the work of gimplify_return_expr for the !aggregate_value_p case.

            PR c++/118874

    gcc/cp/ChangeLog:

            * coroutines.cc (cp_coroutine_transform::build_ramp_function): For
            !aggregate_value_p return force return value into a local temp.

    gcc/testsuite/ChangeLog:

            * g++.dg/coroutines/torture/pr118874.C: New test.
