[Ada] Full view of tagged type with ptype
When evaluating an expression, if it is of a tagged type, GDB reads
the tag in memory and deduces the full view. At parsing time, however,
this operation is done only in the case of OP_VAR_VALUE. ptype does
not go through a full evaluation of expressions so it may return some
odd results:
(gdb) print c.menu_name
$1 = 0x0
(gdb) ptype $
type = system.strings.string_access
(gdb) ptype c.menu_name
type = <void>
This change removes this peculiarity by extending the tag resolution
to UNOP_IND and STRUCTOP_STRUCT. As in the case of OP_VAR_VALUE, this
implies switching from EVAL_AVOID_SIDE_EFFECTS to EVAL_NORMAL when a
tagged type is dereferenced.
gdb/
* ada-lang.c (ada_evaluate_subexp): Resolve tagged types to
full view in the case of UNOP_IND and STRUCTOP_STRUCT.
gdb/testsuite/
* gdb.ada/tagged_access: New testcase.
