    c++: bogus -Wparentheses warning [PR112765]

    We need to consistently look through implicit INDIRECT_REF when
    setting/checking for -Wparentheses warning suppression.  In passing
    use the recently introduced STRIP_REFERENCE_REF helper some more.

            PR c++/112765

    gcc/cp/ChangeLog:

            * pt.cc (tsubst_expr) <case MODOP_EXPR>: Look through implicit
            INDIRECT_REF when propagating -Wparentheses warning suppression.
            * semantics.cc (maybe_warn_unparenthesized_assignment): Replace
            REFERENCE_REF_P handling with STRIP_REFERENCE_REF.
            (finish_parenthesized_expr): Likewise.

    gcc/testsuite/ChangeLog:

            * g++.dg/warn/Wparentheses-33.C: New test.=
