2302 /* Mechanism for co-ordinating the selection of a specific
2303    architecture.
2304
2305    GDB targets (*-tdep.c) can register an interest in a specific
2306    architecture.  Other GDB components can register a need to maintain
2307    per-architecture data.
2308
2309    The mechanisms below ensures that there is only a loose connection
2310    between the set-architecture command and the various GDB
2311    components.  Each component can independently register their need
2312    to maintain architecture specific data with gdbarch.
2313
2314    Pragmatics:
2315
2316    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
2317    didn't scale.
2318
2319    The more traditional mega-struct containing architecture specific
2320    data for all the various GDB components was also considered.  Since
2321    GDB is built from a variable number of (fairly independent)
2322    components it was determined that the global aproach was not
2323    applicable. */

2328    Register support for the specified ARCHITECTURE with GDB.  When

2330    selected, the corresponding INIT function is called.
2331
2332    --
2333
2334    The INIT function takes two parameters: INFO which contains the
2335    information available to gdbarch about the (possibly new)
2336    architecture; ARCHES which is a list of the previously created
2337    ``struct gdbarch'' for this architecture.
2338
2339    The INIT function parameter INFO shall, as far as possible, be
2340    pre-initialized with information obtained from INFO.ABFD or
2341    previously selected architecture (if similar).
2342
2343    The INIT function shall return any of: NULL - indicating that it
2344    doesn't recognize the selected architecture; an existing ``struct
2345    gdbarch'' from the ARCHES list - indicating that the new
2346    architecture is just a synonym for an earlier architecture (see
2347    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
2348    - that describes the selected architecture (see gdbarch_alloc()).
2349
2350    The DUMP_TDEP function shall print out all target specific values.
2351    Care should be taken to ensure that the function works in both the
2352    multi-arch and non- multi-arch cases. */
