2421    architecture.
2422
2423    GDB targets (*-tdep.c) can register an interest in a specific
2424    architecture.  Other GDB components can register a need to maintain
2425    per-architecture data.
2426
2427    The mechanisms below ensures that there is only a loose connection
2428    between the set-architecture command and the various GDB
2429    components.  Each component can independently register their need
2430    to maintain architecture specific data with gdbarch.
2431
2432    Pragmatics:
2433
2434    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
2435    didn't scale.
2436
2437    The more traditional mega-struct containing architecture specific
2438    data for all the various GDB components was also considered.  Since
2439    GDB is built from a variable number of (fairly independent)
2440    components it was determined that the global aproach was not

2448    selected, the corresponding INIT function is called.
2449

2451
2452    The INIT function takes two parameters: INFO which contains the
2453    information available to gdbarch about the (possibly new)
2454    architecture; ARCHES which is a list of the previously created
2455    ``struct gdbarch'' for this architecture.

2458    information obtained from INFO.ABFD or the previously selected
2459    architecture.
2460
2461    The ARCHES parameter is a linked list (sorted most recently used)
2462    of all the previously created architures for this architecture
2463    family.  The (possibly NULL) ARCHES->gdbarch can used to access
2464    values from the previously selected architecture for this
2465    architecture family.  The global ``current_gdbarch'' shall not be
2466    used.
2467
2468    The INIT function shall return any of: NULL - indicating that it
2469    doesn't recognize the selected architecture; an existing ``struct
2470    gdbarch'' from the ARCHES list - indicating that the new
2471    architecture is just a synonym for an earlier architecture (see
2472    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
2473    - that describes the selected architecture (see gdbarch_alloc()).
2474
2475    The DUMP_TDEP function shall print out all target specific values.
