2373    GDB targets (*-tdep.c) can register an interest in a specific
2374    architecture.  Other GDB components can register a need to maintain
2375    per-architecture data.
2376
2377    The mechanisms below ensures that there is only a loose connection
2378    between the set-architecture command and the various GDB
2379    components.  Each component can independently register their need
2380    to maintain architecture specific data with gdbarch.
2381
2382    Pragmatics:
2383
2384    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
2385    didn't scale.
2386
2387    The more traditional mega-struct containing architecture specific
2388    data for all the various GDB components was also considered.  Since
2389    GDB is built from a variable number of (fairly independent)
2390    components it was determined that the global aproach was not

2412    doesn't recognize the selected architecture; an existing ``struct
2413    gdbarch'' from the ARCHES list - indicating that the new
2414    architecture is just a synonym for an earlier architecture (see
2415    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
2416    - that describes the selected architecture (see gdbarch_alloc()).
