    gdb            : ChangeLog eval.c gdbtypes.h gdbtypes.c 
                     valarith.c valops.c value.h 

Log message:
    PR c++/13225
    * eval.c (evaluate_subexp_standard): Do not construct
    an array of types; pass the value array directly to
    find_overload_match.
    * gdbtypes.h (NULL_POINTER_CONVERSION_BADNESS): Declare.
    (rank_function): Take an array of values instead of types.
    (rank_one_type): Add struct value * parameter.
    * gdbtypes.c (NULL_POINTER_CONVERSION_BADNESS): Define.
    (rank_function): For each argument, pass the argument's
    value to rank_one_type.
    (rank_one_type): Add VALUE parameter.
    If the parameter type is a pointer and the argument type
    is an integer, return NULL_POINTER_CONVERSION_BADNESS if
    VALUE is zero.
    Update all calls to rank_one_type, passing NULL for new
    VALUE parameter.
    * valarith.c (value_user_defined_cpp_op): Do not construct
    an array of types; pass the value array directly to
    find_overload_match.
    * valops.c (find_overload_method_list): Take an array of
    values instead of types.
    Save the type of OBJP for later use.
    Update calls to find_oload_champ, and find_oload_champ_namespace.
    (find_oload_champ_namespace): Take an array of values instead
    of types.
    (find_oload_champ_namespace_loop): Likewise.
    (find_oload_champ): Likewise.
    (classify_oload_match): Inspect all arguments
    until INCOMPATIBLE is found. Return the worst badness found
    otherwise.
    (compare_parameters): Update call to rank_one_type.
    * value.h (find_overload_match): Take an array of values instead
    of types.
