Support data_capability and code_capability types + update target description
Support the data_capability and code_capability types, which the capability counterparts of the data_ptr and code_ptr types. Adjust the Morello C registers to be of data_capability and code_capability types. gdb/ChangeLog: 2020-11-11 Luis Machado <luis.machado@arm.com> * aarch64-tdep.c (aarch64_address_class_type_flags) (aarch64_address_class_type_flags_to_name) (aarch64_address_class_name_to_type_flags): Use TYPE_INSTANCE_FLAG_CAPABILITY instead of TYPE_INSTANCE_FLAG_ADDRESS_CLASS_1. (aarch64_gdbarch_init): Set capability size to 128. * features/aarch64-capability.c: Regenerate. * features/aarch64-capability.xml: Update C register types. * gdbarch.c: Regenerate. * gdbarch.h: Regenerate. * gdbarch.sh (code_capability_bit, data_capability) (dwarf2_capability_size): Remove. * gdbtypes.c (gdbtypes_post_init): Initialize data_capability and code_capability types. * gdbtypes.h (TYPE_INSTANCE_FLAG_ADDRESS_CLASS_ALL): Include TYPE_INSTANCE_FLAG_CAPABILITY in the list of address classes.
