2337
2338    GDB targets (*-tdep.c) can register an interest in a specific
2339    architecture.  Other GDB components can register a need to maintain
2340    per-architecture data.
2341
2342    The mechanisms below ensures that there is only a loose connection
2343    between the set-architecture command and the various GDB
2344    components.  Each component can independently register their need
2345    to maintain architecture specific data with gdbarch.
2346
2347    Pragmatics:
2348
2349    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
2350    didn't scale.
2351
2352    The more traditional mega-struct containing architecture specific
2353    data for all the various GDB components was also considered.  Since
2354    GDB is built from a variable number of (fairly independent)
2355    components it was determined that the global aproach was not

2377    doesn't recognize the selected architecture; an existing ``struct

2379    architecture is just a synonym for an earlier architecture (see
2380    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
2381    - that describes the selected architecture (see gdbarch_alloc()).
2382
