This commit moves the code to handle lwp_info.arch_private for Linux x86 into a new shared file, nat/x86-linux.c. gdb/ChangeLog: * nat/x86-linux.h: New file. * nat/x86-linux.c: Likewise. * Makefile.in (HFILES_NO_SRCDIR): Add nat/x86-linux.h. (x86-linux.o): New rule. * config/i386/linux.mh (NATDEPFILES): Add x86-linux.o. * config/i386/linux64.mh (NATDEPFILES): Likewise. * nat/linux-nat.h (struct arch_lwp_info): New forward declaration. (lwp_set_arch_private_info): New declaration. (lwp_arch_private_info): Likewise. * linux-nat.c (lwp_set_arch_private_info): New function. (lwp_arch_private_info): Likewise. * x86-linux-nat.c: Include nat/x86-linux.h. (arch_lwp_info): Removed structure. (update_debug_registers_callback): Use lwp_set_debug_registers_changed. (x86_linux_prepare_to_resume): Use lwp_debug_registers_changed and lwp_set_debug_registers_changed. (x86_linux_new_thread): Use lwp_set_debug_registers_changed. gdb/gdbserver/ChangeLog: * Makefile.in (x86-linux.o): New rule. * configure.srv: Add x86-linux.o to relevant targets. * linux-low.c (lwp_set_arch_private_info): New function. (lwp_arch_private_info): Likewise. * linux-x86-low.c: Include nat/x86-linux.h. (arch_lwp_info): Removed structure. (update_debug_registers_callback): Use lwp_set_debug_registers_changed. (x86_linux_prepare_to_resume): Use lwp_debug_registers_changed and lwp_set_debug_registers_changed. (x86_linux_new_thread): Use lwp_set_debug_registers_changed.
