2444    architecture.
2445
2446    GDB targets (*-tdep.c) can register an interest in a specific
2447    architecture.  Other GDB components can register a need to maintain
2448    per-architecture data.
2449
2450    The mechanisms below ensures that there is only a loose connection
2451    between the set-architecture command and the various GDB
2452    components.  Each component can independently register their need
2453    to maintain architecture specific data with gdbarch.
2454
2455    Pragmatics:
2456
2457    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
2458    didn't scale.
2459
2460    The more traditional mega-struct containing architecture specific
2461    data for all the various GDB components was also considered.  Since
2462    GDB is built from a variable number of (fairly independent)
2463    components it was determined that the global aproach was not

2471    selected, the corresponding INIT function is called.
2472
2473    --
2474
2475    The INIT function takes two parameters: INFO which contains the
2476    information available to gdbarch about the (possibly new)
2477    architecture; ARCHES which is a list of the previously created
2478    ``struct gdbarch'' for this architecture.
2479
2480    The INFO parameter is, as far as possible, be pre-initialized with
2481    information obtained from INFO.ABFD or the previously selected
2482    architecture.
2483
2484    The ARCHES parameter is a linked list (sorted most recently used)
2485    of all the previously created architures for this architecture
2486    family.  The (possibly NULL) ARCHES->gdbarch can used to access
2487    values from the previously selected architecture for this
2488    architecture family.  The global ``current_gdbarch'' shall not be
2489    used.
2490
2491    The INIT function shall return any of: NULL - indicating that it
2492    doesn't recognize the selected architecture; an existing ``struct
2493    gdbarch'' from the ARCHES list - indicating that the new
2494    architecture is just a synonym for an earlier architecture (see
2495    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
2496    - that describes the selected architecture (see gdbarch_alloc()).
2497
2498    The DUMP_TDEP function shall print out all target specific values.
