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_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.
