This patch enhances the debugger to distinguish between fat pointers
that represent either: array types, or array access types. In the latter
case, the object/type is encoded as a typedef type pointing to the fat
pointer.
The first part of the change is to adjust ada_check_typedef to avoid
stripping the typedef layer when it points to a fat pointer. The rest
of the patch is adjustments required in various places to deal with
the fact that the type is uses might now be a typedef.
gdb/ChangeLog:
* ada-lang.h (ada_coerce_to_simple_array): Add declaration.
* ada-lang.c (ada_typedef_target_type): New function.
(desc_base_type): Add handling of fat pointer typedefs.
(ada_coerce_to_simple_array): Make non-static.
(decode_packed_array_bitsize): Add handling of fat pointer typedefs.
Add assertion.
(ada_template_to_fixed_record_type_1, ada_to_fixed_type)
(ada_check_typedef): Add handling of fat pointer typedefs.
(ada_evaluate_subexp) [OP_FUNCALL]: Likewise.
* ada-typeprint.c (ada_print_type): Add handling of fat pointer
typedefs.
* ada-valprint.c (ada_val_print_1): Convert fat pointers that are not
array accesses to simple arrays rather than simple array pointers.
(ada_value_print): In the case of array descriptors, do not print
the value type description unless it is an array access.
gdb/testsuite/ChangeLog:
* gdb.ada/lang_switch.exp: Correct expected parameter value.
gdb/doc/ChangeLog:
* gdb.texinfo (Ada Glitches): Remove paragraph describing the
occasional case where the debugger prints an array address
instead of the array itself.
