This commit introduces a new function, x86_debug_reg_state, that shared x86 code can use to access the local mirror of a process's debug registers. This function already existed in GDB and was in use by GDB's x86_linux_prepare_to_resume. An equivalent was written for gdbserver and gdbserver's x86_linux_prepare_to_resume was modified to use it. gdb/ChangeLog: * x86-nat.h (x86_debug_reg_state): Move declaration to... * nat/x86-dregs.h (x86_debug_reg_state): New declaration. gdb/gdbserver/ChangeLog: * linux-x86-low.c (x86_debug_reg_state): New function. (x86_linux_prepare_to_resume): Use the above.
