2213
2214    GDB targets (*-tdep.c) can register an interest in a specific
2215    architecture.  Other GDB components can register a need to maintain
2216    per-architecture data.
2217
2218    The mechanisms below ensures that there is only a loose connection
2219    between the set-architecture command and the various GDB
2220    components.  Each component can independently register their need
2221    to maintain architecture specific data with gdbarch.
2222
2223    Pragmatics:
2224
2225    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
2226    didn't scale.
2227
2228    The more traditional mega-struct containing architecture specific
2229    data for all the various GDB components was also considered.  Since
2230    GDB is built from a variable number of (fairly independent)
2231    components it was determined that the global aproach was not

2249    pre-initialized with information obtained from INFO.ABFD or
2250    previously selected architecture (if similar).

2253    doesn't recognize the selected architecture; an existing ``struct
2254    gdbarch'' from the ARCHES list - indicating that the new
2255    architecture is just a synonym for an earlier architecture (see

2257    - that describes the selected architecture (see gdbarch_alloc()).
