803 architecture.
804
805 GDB targets (*-tdep.c) can register an interest in a specific
806 architecture. Other GDB components can register a need to maintain
807 per-architecture data.
808
809 The mechanisms below ensures that there is only a loose connection
810 between the set-architecture command and the various GDB
811 components. Each component can independantly register their need
812 to maintain architecture specific data with gdbarch.
813
814 Pragmatics:
815
816 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
817 didn't scale.
818
819 The more traditional mega-struct containing architecture specific
820 data for all the various GDB components was also considered. Since
821 GDB is built from a variable number of (fairly independant)
822 components it was determined that the global aproach was not
823 applicable. */

826/* Register a new architectural family with GDB.

830 selected, the corresponding INIT function is called.
831
832 --
833
834 The INIT function takes two parameters: INFO which contains the
835 information available to gdbarch about the (possibly new)
836 architecture; ARCHES which is a list of the previously created
837 ``struct gdbarch'' for this architecture.
838
839 The INIT function parameter INFO shall, as far as possible, be
840 pre-initialized with information obtained from INFO.ABFD or
841 previously selected architecture (if similar). INIT shall ensure
842 that the INFO.BYTE_ORDER is non-zero.
843
844 The INIT function shall return any of: NULL - indicating that it
845 doesn't reconize the selected architecture; an existing ``struct
846 gdbarch'' from the ARCHES list - indicating that the new
847 architecture is just a synonym for an earlier architecture (see
848 gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
849 - that describes the selected architecture (see
