This patch enables capability reads from memory, including the tag bit. It enables both native GDB and gdbserver to do so. gdb/ChangeLog: 2021-01-15 Luis Machado <luis.machado@arm.com> * aarch64-linux-nat.c (aarch64_linux_nat_target) <read_capability>: New function override. (aarch64_linux_nat_target::read_capability): New function. (maint_print_cap_from_addr_cmd): New function. (add_show_debug_regs_command): Register new maintenance command. * aarch64-linux-tdep.c: Include target.h. (aarch64_linux_get_cap_tag_from_address): New function. (aarch64_linux_init_abi): Register hook for gdbarch_get_cap_tag_from_address * arch-utils.c (default_get_cap_tag_from_address): New function. * arch-utils.h (default_get_cap_tag_from_address): New prototype. * configure.nat: Add nat/aarch64-cap-linux.o to the list of object files for AArch64-Linux. * gdbarch.c: Regenerate. * gdbarch.h: Regenerate. * gdbarch.sh (get_cap_tag_from_address): New gdbarch hook. * nat/aarch64-cap-linux.c: New file. * nat/aarch64-cap-linux.h (aarch64_linux_read_capability): New prototype. * remote.c (remote_target) <read_capability>: New function override. (PACKET_qXfer_capability): New enum. (remote_target::xfer_partial): Handle TARGET_OBJECT_CAPABILITY. (remote_target::read_capability): New member function. (_initialize_remote): Add new packet configuration. * target-delegates.c: Regenerate. * target.c (target_read_capability): New function. * target.h (target_object) <TARGET_OBJECT_CAPABILITY>: New enum field. (struct target_ops) <read_capability>: New virtual member function. (target_read_capability): New prototype. * valprint.c (generic_value_print_capability): Handle tags from capabilities stored in memory. * value.c (value_fetch_lazy_memory): Fetch tag if reading a capability. gdbserver/ChangeLog 2021-01-15 Luis Machado <luis.machado@arm.com> * configure.srv: Add nat/aarch64-cap-linux.o to the list of object files for AArch64-Linux * linux-aarch64-low.cc (aarch64_target) <supports_qxfer_capability> <qxfer_capability>: New member function overrides. (aarch64_target::supports_qxfer_capability): New function. (aarch64_target::qxfer_capability): New function. * server.cc (handle_qxfer_capability): New function.
