This patch adds a target description and feature "mte" for aarch64. It includes one new register, tag_ctl, that can be used to configure the tag generation rules and sync/async modes. It is 64-bit in size. The patch also adjusts the code that creates the target descriptions at runtime based on CPU feature checks. gdb/ChangeLog: 2021-03-24 Luis Machado <luis.machado@linaro.org> * aarch64-linux-nat.c (aarch64_linux_nat_target::read_description): Take MTE flag into account. Slight refactor to hwcap flag checking. * aarch64-linux-tdep.c (aarch64_linux_core_read_description): Likewise. * aarch64-tdep.c (tdesc_aarch64_list): Add one more dimension for MTE. (aarch64_read_description): Add mte_p parameter and update to use it. Update the documentation. (aarch64_gdbarch_init): Update call to aarch64_read_description. * aarch64-tdep.h (aarch64_read_description): Add mte_p parameter. * arch/aarch64.c: Include ../features/aarch64-mte.c. (aarch64_create_target_description): Add mte_p parameter and update the code to use it. * arch/aarch64.h (aarch64_create_target_description): Add mte_p parameter. * features/Makefile (FEATURE_XMLFILES): Add aarch64-mte.xml. * features/aarch64-mte.c: New file, generated. * features/aarch64-mte.xml: New file. gdbserver/ChangeLog: 2021-03-24 Luis Machado <luis.machado@linaro.org> * linux-aarch64-ipa.cc (get_ipa_tdesc): Update call to aarch64_linux_read_description. (initialize_low_tracepoint): Likewise. * linux-aarch64-low.cc (aarch64_target::low_arch_setup): Take MTE flag into account. * linux-aarch64-tdesc.cc (tdesc_aarch64_list): Add one more dimension for MTE. (aarch64_linux_read_description): Add mte_p parameter and update to use it. * linux-aarch64-tdesc.h (aarch64_linux_read_description): Add mte_p parameter.
