2360    GDB targets (*-tdep.c) can register an interest in a specific
2361    architecture.  Other GDB components can register a need to maintain
2362    per-architecture data.
2363
2364    The mechanisms below ensures that there is only a loose connection
2365    between the set-architecture command and the various GDB
2366    components.  Each component can independently register their need
2367    to maintain architecture specific data with gdbarch.
2368
2369    Pragmatics:
2370
2371    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
2372    didn't scale.
2373
2374    The more traditional mega-struct containing architecture specific
2375    data for all the various GDB components was also considered.  Since
2376    GDB is built from a variable number of (fairly independent)
2377    components it was determined that the global aproach was not

2399    doesn't recognize the selected architecture; an existing ``struct
2400    gdbarch'' from the ARCHES list - indicating that the new
2401    architecture is just a synonym for an earlier architecture (see
2402    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
2403    - that describes the selected architecture (see gdbarch_alloc()).
2404
