The code on creating i386-linux target descriptions are quite similar between GDB and GDBserver, so this patch moves them into a shared file arch/i386.c. I didn't name it as i386-linux.c, because I want to reuse it to create other i386 non-linux target descriptions later. gdb: 2017-09-05 Yao Qi <yao.qi@linaro.org> * Makefile.in (ALL_TARGET_OBS): Add i386.o. (SFILES): Add arch/i386.c. (HFILES_NO_SRCDIR): Add arch/i386.h. * arch/i386.c: New file. * arch/i386.h: New file. * arch/tdesc.h (allocate_target_description): Declare. (set_tdesc_architecture): Declare. (set_tdesc_osabi): Declare. * configure.tgt (i[34567]86-*-linux*): Add i386.o. * i386-linux-tdep.c: Don't include ../features/i386/32bit-XXX.c. include arch/i386.h. (i386_linux_read_description): Remove code and call i386_create_target_description. (set_tdesc_architecture): New function. (set_tdesc_osabi): New function. * target-descriptions.h (allocate_target_description): Remove. gdb/gdbserver: 2017-09-05 Yao Qi <yao.qi@linaro.org> * Makefile.in (arch-i386.o): New rule. * configure.srv (i[34567]86-*-linux*): Add arch-i386.o. (x86_64-*-linux*): Likewise. * linux-x86-tdesc.c: Don't include ../features/i386/32bit-XXX.c, include arch/i386.h. (i386_linux_read_description): Remove code and call i386_create_target_description. * tdesc.c (allocate_target_description): New function. * tdesc.h (set_tdesc_architecture): Remove declaration. (set_tdesc_osabi): Likewise.
