2342    architecture.
2343
2344    GDB targets (*-tdep.c) can register an interest in a specific
2345    architecture.  Other GDB components can register a need to maintain
2346    per-architecture data.
2347
2348    The mechanisms below ensures that there is only a loose connection
2349    between the set-architecture command and the various GDB
2350    components.  Each component can independently register their need
2351    to maintain architecture specific data with gdbarch.
2352
2353    Pragmatics:
2354
2355    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
2356    didn't scale.
2357
2358    The more traditional mega-struct containing architecture specific
2359    data for all the various GDB components was also considered.  Since
2360    GDB is built from a variable number of (fairly independent)
2361    components it was determined that the global aproach was not
2362    applicable. */

2376    ``struct gdbarch'' for this architecture.

2379    pre-initialized with information obtained from INFO.ABFD or
2380    previously selected architecture (if similar).
2381
2382    The INIT function shall return any of: NULL - indicating that it
2383    doesn't recognize the selected architecture; an existing ``struct
2384    gdbarch'' from the ARCHES list - indicating that the new
2385    architecture is just a synonym for an earlier architecture (see
2386    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
2387    - that describes the selected architecture (see gdbarch_alloc()).
2388
