Add support for dynamic type lengths
In Ada, a type with variant parts can have a variable length. This
patch adds support for this to gdb, by integrating the length
computation into the dynamic type resolution code.
gdb/ChangeLog
2020-04-24 Tom Tromey <tromey@adacore.com>
* dwarf2/read.c (read_structure_type): Handle dynamic length.
* gdbtypes.c (is_dynamic_type_internal): Check
TYPE_HAS_DYNAMIC_LENGTH.
(resolve_dynamic_type_internal): Use TYPE_DYNAMIC_LENGTH.
* gdbtypes.h (TYPE_HAS_DYNAMIC_LENGTH, TYPE_DYNAMIC_LENGTH):
New macros.
(enum dynamic_prop_node_kind) <DYN_PROP_BYTE_SIZE>: New
constant.
