/* Mechanism for co-ordinating the selection of a specific

   GDB targets (*-tdep.c) can register an interest in a specific
   architecture.  Other GDB components can register a need to maintain
   per-architecture data.

   The mechanisms below ensures that there is only a loose connection
   between the set-architecture command and the various GDB
   components.  Each component can independantly register their need
   to maintain architecture specific data with gdbarch.

   Pragmatics:

   Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
   didn't scale.

   The more traditional mega-struct containing architecture specific
   data for all the various GDB components was also considered.  Since
   GDB is built from a variable number of (fairly independant)
   components it was determined that the global aproach was not
   applicable. */

   information available to gdbarch about the (possibly new)
   architecture; ARCHES which is a list of the previously created
   ``struct gdbarch'' for this architecture.

   The INIT function parameter INFO shall, as far as possible, be

   previously selected architecture (if similar).  INIT shall ensure
   that the INFO.BYTE_ORDER is non-zero.

   The INIT function shall return any of: NULL - indicating that it
   doesn't reconize the selected architecture; an existing ``struct
   gdbarch'' from the ARCHES list - indicating that the new
   architecture is just a synonym for an earlier architecture (see
