--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
build_atomic_assign does not handle this in a reasonable fashion.
Note there is code like :
  if (modifycode !=3D NOP_EXPR)
    add_stmt (rhs);

  /* NOP_EXPR indicates it's a straight store of the RHS. Simply issue
     an atomic_store.  */
  if (modifycode =3D=3D NOP_EXPR)
    {
...
      /* VAL is the value which was stored, return a COMPOUND_STMT of
         the statement and that value.  */
      return build2 (COMPOUND_EXPR, nonatomic_lhs_type, compound_stmt, val);
    }

Which definitely could be improved too.=
