2704    architecture.
2705
2706    GDB targets (*-tdep.c) can register an interest in a specific
2707    architecture.  Other GDB components can register a need to maintain
2708    per-architecture data.
2709
2710    The mechanisms below ensures that there is only a loose connection
2711    between the set-architecture command and the various GDB
2712    components.  Each component can independently register their need
2713    to maintain architecture specific data with gdbarch.
2714
2715    Pragmatics:
2716
2717    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
2718    didn't scale.
2719
2720    The more traditional mega-struct containing architecture specific
2721    data for all the various GDB components was also considered.  Since
2722    GDB is built from a variable number of (fairly independent)
2723    components it was determined that the global aproach was not
2724    applicable. */

2729    Register support for the specified ARCHITECTURE with GDB.  When

2731    selected, the corresponding INIT function is called.
2732
2733    --
2734
2735    The INIT function takes two parameters: INFO which contains the
2736    information available to gdbarch about the (possibly new)
2737    architecture; ARCHES which is a list of the previously created
2738    ``struct gdbarch'' for this architecture.
2739
2740    The INFO parameter is, as far as possible, be pre-initialized with
2741    information obtained from INFO.ABFD or the previously selected
2742    architecture.
2743
2744    The ARCHES parameter is a linked list (sorted most recently used)
2745    of all the previously created architures for this architecture
2746    family.  The (possibly NULL) ARCHES->gdbarch can used to access
2747    values from the previously selected architecture for this
2748    architecture family.  The global ``current_gdbarch'' shall not be
2749    used.
2750
2751    The INIT function shall return any of: NULL - indicating that it
2752    doesn't recognize the selected architecture; an existing ``struct
2753    gdbarch'' from the ARCHES list - indicating that the new
2754    architecture is just a synonym for an earlier architecture (see
2755    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
2756    - that describes the selected architecture (see gdbarch_alloc()).
2757
2758    The DUMP_TDEP function shall print out all target specific values.
2759    Care should be taken to ensure that the function works in both the
2760    multi-arch and non- multi-arch cases. */
