2500
2501    GDB targets (*-tdep.c) can register an interest in a specific
2502    architecture.  Other GDB components can register a need to maintain
2503    per-architecture data.
2504
2505    The mechanisms below ensures that there is only a loose connection
2506    between the set-architecture command and the various GDB

2508    to maintain architecture specific data with gdbarch.

2511
2512    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
2513    didn't scale.
2514
2515    The more traditional mega-struct containing architecture specific
2516    data for all the various GDB components was also considered.  Since
2517    GDB is built from a variable number of (fairly independent)

2526    selected, the corresponding INIT function is called.
2527
2528    --
2529
2530    The INIT function takes two parameters: INFO which contains the
2531    information available to gdbarch about the (possibly new)
2532    architecture; ARCHES which is a list of the previously created
2533    ``struct gdbarch'' for this architecture.
2534
2535    The INFO parameter is, as far as possible, be pre-initialized with
2536    information obtained from INFO.ABFD or the previously selected
2537    architecture.
2538
2539    The ARCHES parameter is a linked list (sorted most recently used)
2540    of all the previously created architures for this architecture
2541    family.  The (possibly NULL) ARCHES->gdbarch can used to access
2542    values from the previously selected architecture for this
2543    architecture family.  The global ``current_gdbarch'' shall not be
2544    used.
2545
2546    The INIT function shall return any of: NULL - indicating that it
2547    doesn't recognize the selected architecture; an existing ``struct
2548    gdbarch'' from the ARCHES list - indicating that the new
2549    architecture is just a synonym for an earlier architecture (see
2550    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
2551    - that describes the selected architecture (see gdbarch_alloc()).
2552
2553    The DUMP_TDEP function shall print out all target specific values.
2554    Care should be taken to ensure that the function works in both the
