2008-10-02 Jan Kratochvil <jan.kratochvil@redhat.com>
Replace TYPE_ARRAY_{UPPER,LOWER}_BOUND_TYPE by a bit if {un,}defined.
* c-typeprint.c (c_type_print_varspec_suffix), m2-typeprint.c
(m2_array), p-typeprint.c (pascal_type_print_varspec_prefix),
valops.c (value_cast), varobj.c (c_number_of_children): Replace
TYPE_ARRAY_UPPER_BOUND_TYPE compared to BOUND_CANNOT_BE_DETERMINED by
TYPE_ARRAY_UPPER_BOUND_IS_UNDEFINED.
* parse.c (follow_types): Use TYPE_ARRAY_UPPER_BOUND_IS_UNDEFINED.
* f-valprint.c (f77_get_dynamic_upperbound): Replace with ...
(f77_get_upperbound): ... this function handling now only
TYPE_ARRAY_UPPER_BOUND_IS_UNDEFINED.
(f77_get_dynamic_lowerbound): Replace with ...
(f77_get_lowerbound): ... this function handling now only
TYPE_ARRAY_LOWER_BOUND_IS_UNDEFINED.
(f77_get_dynamic_length_of_aggregate, f77_create_arrayprint_offset_tbl):
Update their callers.
* eval.c (evaluate_subexp_standard): Update their callers.
* f-lang.h (f77_get_dynamic_upperbound, f77_get_upperbound)
(f77_get_dynamic_lowerbound, f77_get_lowerbound): Update their
prototypes.
(BOUND_FETCH_OK, BOUND_FETCH_ERROR): Remove.
* f-typeprint.c (f_type_print_varspec_suffix, f_type_print_base): Remove
the lower_bound_was_default variable. Update the
f77_get_dynamic_upperbound, f77_get_upperbound and
TYPE_ARRAY_UPPER_BOUND_TYPE calls.
* gdbtypes.c (print_bound_type): Remove the function.
(recursive_dump_type): Remove its calls printing UPPER_BOUND_TYPE and
LOWER_BOUND_TYPE.
* gdbtypes.h (enum array_bound_type): Remove.
(struct main_type): Remove the fields upper_bound_type and
lower_bound_type. Comment the new overload of the field artificial.
(TYPE_ARRAY_UPPER_BOUND_TYPE): Replace by ...
(TYPE_ARRAY_UPPER_BOUND_IS_UNDEFINED): ... this macro.
(TYPE_ARRAY_LOWER_BOUND_TYPE): Replace by ...
(TYPE_ARRAY_LOWER_BOUND_IS_UNDEFINED): ... this macro.
gdb/testsuite/
2008-10-02 Jan Kratochvil <jan.kratochvil@redhat.com>
* gdb.base/maint.exp (maint print type): Remove printing
UPPER_BOUND_TYPE and LOWER_BOUND_TYPE.

* Mon Nov 3 2008 Jan Kratochvil <jan.kratochvil@redhat.com> - 6.8-25
- Fix the variable-length-arrays support (BZ 468266, feature BZ 377541).
- Fix the debuginfo-install suggestions for missing base packages (BZ 467901),
also update the rpm/yum code to no longer require _RPM_4_4_COMPAT.
* Tue Sep 2 2008 Jan Kratochvil <jan.kratochvil@redhat.com> - 6.8-24
- Fix PIE patch regression for loading binaries from valgrind (BZ 460319).
