   to maintain architecture specific data with gdbarch.

702
 
703

704
   didn't scale.
705
 
706
   The more traditional mega-struct containing architecture specific
707
   data for all the various GDB components was also considered.  Since
708
   GDB is built from a variable number of (fairly independent)

   ``struct gdbarch'' for this architecture.

727
   information obtained from INFO.ABFD or the global defaults.
728
 
729
   The ARCHES parameter is a linked list (sorted most recently used)
730
   of all the previously created architures for this architecture
731
   family.  The (possibly NULL) ARCHES->gdbarch can used to access
732
   values from the previously selected architecture for this
733
   architecture family.  The global ``current_gdbarch'' shall not be
734
   used.
735
 
736
   The INIT function shall return any of: NULL - indicating that it
737
   doesn't recognize the selected architecture; an existing ``struct
738
   gdbarch'' from the ARCHES list - indicating that the new
739
   architecture is just a synonym for an earlier architecture (see
740
   gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
741
   - that describes the selected architecture (see gdbarch_alloc()).
742
 
743
   The DUMP_TDEP function shall print out all target specific values.
