2017-09-05  Yao Qi  <yao.qi@linaro.org>

	* amd64-tdep.c (amd64_target_description): Create target
	descriptions.
	(_initialize_amd64_tdep): Don't call functions
	initialize_tdesc_amd64_*.  Add self tests.
	* arch/amd64.c (amd64_create_target_description): Add parameter
	is_linux.  Call set_tdesc_osabi if is_linux is true.
	* arch/amd64.h (amd64_create_target_description): Update the
	declaration.
	* arch/i386.c (i386_create_target_description): Add parameter
	is_linux.  Call set_tdesc_osabi if is_linux is true.
	* arch/i386.h (i386_create_target_description): Update
	declaration.
	* configure.tgt: Add i386.o to gdb_target_obs.
	* features/Makefile (XMLTOC): Remove i386/*.xml.
	* features/i386/amd64-avx-avx512.c: Remove.
	* features/i386/amd64-avx-mpx-avx512-pku.c: Remove.
	* features/i386/amd64-avx-mpx.c: Remove.
	* features/i386/amd64-avx.c: Remove.
	* features/i386/amd64-mpx.c: Remove.
	* features/i386/amd64.c: Remove.
	* features/i386/i386-avx-avx512.c: Remove.
	* features/i386/i386-avx-mpx-avx512-pku.c: Remove.
	* features/i386/i386-avx-mpx.c: Remove.
	* features/i386/i386-avx.c: Remove.
	* features/i386/i386-mmx.c: Remove.
	* features/i386/i386-mpx.c: Remove.
	* features/i386/i386.c: Remove.
	* i386-tdep.c: Don't include features/i386/i386*.c., include
	target-descriptions.h and arch/i386.h.
	(i386_target_description): Create target descriptions.
	(i386_gdbarch_init): Don't call initialize_tdesc_i386_*
	functions.  Do self tests.

gdb/gdbserver:

2017-09-05  Yao Qi  <yao.qi@linaro.org>

	* configure.srv (srv_i386_regobj): Remove.
	(srv_amd64_regobj): Remove.
	(srv_regobj): Set it to "" for x86 non-linux targets.
	* linux-x86-tdesc.c (i386_linux_read_description):
	* lynx-i386-low.c: Include x86-xstate.h and arch/i386.h.
	(init_registers_i386): Remove the declaration.
	(tdesc_i386): Remove the declaration.
	(lynx_i386_arch_setup): Call i386_create_target_description.
	* nto-x86-low.c: Likewise.
	* win32-i386-low.c [__x86_64__]: include arch/amd64.h.
	[!__x86_64__]: include arch/i386.h.
	(i386_arch_setup) [__x86_64__]: Call amd64_create_target_description.
