2411    architecture.
2412
2413    GDB targets (*-tdep.c) can register an interest in a specific
2414    architecture.  Other GDB components can register a need to maintain
2415    per-architecture data.
2416
2417    The mechanisms below ensures that there is only a loose connection
2418    between the set-architecture command and the various GDB
2419    components.  Each component can independently register their need
2420    to maintain architecture specific data with gdbarch.
2421
2422    Pragmatics:
2423
2424    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
2425    didn't scale.
2426
2427    The more traditional mega-struct containing architecture specific
2428    data for all the various GDB components was also considered.  Since
2429    GDB is built from a variable number of (fairly independent)
2430    components it was determined that the global aproach was not

2438    selected, the corresponding INIT function is called.
2439

2441
2442    The INIT function takes two parameters: INFO which contains the
2443    information available to gdbarch about the (possibly new)
2444    architecture; ARCHES which is a list of the previously created
2445    ``struct gdbarch'' for this architecture.

2448    information obtained from INFO.ABFD or the previously selected
2449    architecture.
2450
2451    The ARCHES parameter is a linked list (sorted most recently used)
2452    of all the previously created architures for this architecture
2453    family.  The (possibly NULL) ARCHES->gdbarch can used to access
2454    values from the previously selected architecture for this
2455    architecture family.  The global ``current_gdbarch'' shall not be
2456    used.
2457
2458    The INIT function shall return any of: NULL - indicating that it
2459    doesn't recognize the selected architecture; an existing ``struct
2460    gdbarch'' from the ARCHES list - indicating that the new
2461    architecture is just a synonym for an earlier architecture (see
2462    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
2463    - that describes the selected architecture (see gdbarch_alloc()).
2464
2465    The DUMP_TDEP function shall print out all target specific values.
