-/* 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. */
