2667    architecture.
2668
2669    GDB targets (*-tdep.c) can register an interest in a specific
2670    architecture.  Other GDB components can register a need to maintain
2671    per-architecture data.
2672
2673    The mechanisms below ensures that there is only a loose connection
2674    between the set-architecture command and the various GDB
2675    components.  Each component can independently register their need
2676    to maintain architecture specific data with gdbarch.
2677
2678    Pragmatics:
2679
2680    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
2681    didn't scale.
2682
2683    The more traditional mega-struct containing architecture specific
2684    data for all the various GDB components was also considered.  Since
2685    GDB is built from a variable number of (fairly independent)
2686    components it was determined that the global aproach was not
2687    applicable. */

2692    Register support for the specified ARCHITECTURE with GDB.  When

2694    selected, the corresponding INIT function is called.
2695
2696    --
2697
2698    The INIT function takes two parameters: INFO which contains the
2699    information available to gdbarch about the (possibly new)
2700    architecture; ARCHES which is a list of the previously created
2701    ``struct gdbarch'' for this architecture.
2702
2703    The INFO parameter is, as far as possible, be pre-initialized with
2704    information obtained from INFO.ABFD or the previously selected
2705    architecture.
2706
2707    The ARCHES parameter is a linked list (sorted most recently used)
2708    of all the previously created architures for this architecture
2709    family.  The (possibly NULL) ARCHES->gdbarch can used to access
2710    values from the previously selected architecture for this
2711    architecture family.  The global ``current_gdbarch'' shall not be
2712    used.
2713
2714    The INIT function shall return any of: NULL - indicating that it
2715    doesn't recognize the selected architecture; an existing ``struct
2716    gdbarch'' from the ARCHES list - indicating that the new
2717    architecture is just a synonym for an earlier architecture (see
2718    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
2719    - that describes the selected architecture (see gdbarch_alloc()).
2720
2721    The DUMP_TDEP function shall print out all target specific values.
2722    Care should be taken to ensure that the function works in both the
2723    multi-arch and non- multi-arch cases. */
