-/* We use GDB's gdbarch_register_name function to map GDB register
-   numbers onto names, which we can then look up in the register
-   table.  Since the `set architecture' command can select a new
-   processor variant at run-time, the meanings of the register numbers
-   can change, so we need to make sure the sim uses the same
-   name/number mapping that GDB uses.
-
-   (We don't use the REGISTER_NAME macro, which is a wrapper for
-   gdbarch_register_name.  We #include GDB's "defs.h", which tries to
-   #include GDB's "config.h", but gets ours instead, and REGISTER_NAME
-   ends up not getting defined.  Simpler to just use
-   gdbarch_register_name directly.)
-
-   We used to just use the REGISTER_NAMES macro from GDB's
-   target-dependent header files, which expanded into an initializer
-   for an array of strings.  That was kind of nice, because it meant
-   that libsim.a had only a compile-time dependency on GDB; using
-   gdbarch_register_name directly means that there are now link-time
-   and run-time dependencies too.
-
-   Perhaps the host_callback structure could provide a function for
-   retrieving register names; that would be cleaner.  */
