Convert amd64-linux target descriptions
This patch changes amd64-linux target descriptions so that they can be dynamically generated in both GDB and GDBserver. gdb/gdbserver: 2017-09-05 Yao Qi <yao.qi@linaro.org> * Makefile.in (arch-amd64.o): New rule. * configure.srv: Append arch-amd64.o. * linux-amd64-ipa.c: Include common/x86-xstate.h. (get_ipa_tdesc): Call amd64_linux_read_description. (initialize_low_tracepoint): Don't call init_registers_x32_XXX and init_registers_amd64_XXX. * linux-x86-low.c (x86_linux_read_description): Call amd64_linux_read_description. (x86_get_ipa_tdesc_idx): Call amd64_get_ipa_tdesc_idx. (initialize_low_arch): Don't call init_registers_x32_XXX and init_registers_amd64_XXX. * linux-x86-tdesc-selftest.c: Declare init_registers_amd64_XXX and tdesc_amd64_XXX. [__x86_64__] (amd64_tdesc_test): New function. (initialize_low_tdesc) [__x86_64__]: Call init_registers_x32_XXX and init_registers_amd64_XXX. * linux-x86-tdesc.c: Include arch/amd64.h. (xcr0_to_tdesc_idx): New function. (i386_linux_read_description): New function. (amd64_get_ipa_tdesc_idx): New function. * linux-x86-tdesc.h (amd64_get_ipa_tdesc_idx): Declare. (amd64_get_ipa_tdesc): Declare. gdb: 2017-09-05 Yao Qi <yao.qi@linaro.org> * amd64-linux-tdep.c: Include arch/amd64.h. Don't include features/i386/*.c. (amd64_linux_read_description): Call amd64_create_target_description. * arch/amd64.c: New file. * arch/amd64.h: New file. * configure.tgt (x86_64-*-linux*): Append amd64.o. * Makefile.in (ALL_64_TARGET_OBS): Append amd64.o.
