This commit moves the now-identical low-level Linux x86 debug register code from gdb/x86-linux-nat.c and gdb/gdbserver/linux-x86-low.c into a new shared file gdb/nat/x86-linux-dregs.c. gdb/ChangeLog: * nat/x86-linux-dregs.h: New file. * nat/x86-linux-dregs.c: Likewise. * Makefile.in (HFILES_NO_SRCDIR): Add nat/x86-linux-dregs.h. (x86-linux-dregs.o): New rule. * config/i386/linux.mh (NATDEPFILES): Add x86-linux-dregs.o. * config/i386/linux64.mh (NATDEPFILES): Likewise. * x86-linux-nat.c: Include nat/x86-linux-dregs.h. (u_debugreg_offset): Moved to nat/x86-linux-dregs.c. (x86_linux_dr_get): Likewise. (x86_linux_dr_set): Likewise. (x86_linux_dr_get_addr): Likewise. (x86_linux_dr_get_control): Likewise. (x86_linux_dr_get_status): Likewise. (update_debug_registers_callback): Likewise. (x86_linux_dr_set_control): Likewise. (x86_linux_dr_set_addr): Likewise. (x86_linux_update_debug_registers): Likewise. gdb/gdbserver/ChangeLog: * Makefile.in (x86-linux-dregs.o): New rule. * configure.srv: Add x86-linux-dregs.o to relevant targets. * linux-x86-low.c: Include nat/x86-linux-dregs.h. (u_debugreg_offset): Moved to nat/x86-linux-dregs.c. (x86_linux_dr_get): Likewise. (x86_linux_dr_set): Likewise. (update_debug_registers_callback): Likewise. (x86_linux_dr_set_addr): Likewise. (x86_linux_dr_get_addr): Likewise. (x86_linux_dr_set_control): Likewise. (x86_linux_dr_get_control): Likewise. (x86_linux_dr_get_status): Likewise. (x86_linux_update_debug_registers): Likewise.
