Insight is still a user of deprecated_register_gdbarch_swap, so now it's
broken.  What's the proper replacement for the following -

int
Gdbtk_Register_Init (Tcl_Interp *interp)
{
  Tcl_CreateObjCommand (interp, "gdb_reginfo", gdbtk_call_wrapper,
                        gdb_register_info, NULL);

  /* Register/initialize any architecture specific data */
  setup_architecture_data ();

  deprecated_register_gdbarch_swap (&old_regs, sizeof (old_regs), NULL);
  deprecated_register_gdbarch_swap (&regformat, sizeof (regformat),
NULL);
  deprecated_register_gdbarch_swap (&regtype, sizeof (regtype), NULL);
  deprecated_register_gdbarch_swap (NULL, 0, setup_architecture_data);

  return TCL_OK;
}
