2457
2458    GDB targets (*-tdep.c) can register an interest in a specific
2459    architecture.  Other GDB components can register a need to maintain
2460    per-architecture data.
2461
2462    The mechanisms below ensures that there is only a loose connection
2463    between the set-architecture command and the various GDB
2464    components.  Each component can independently register their need
2465    to maintain architecture specific data with gdbarch.
2466
2467    Pragmatics:
2468
2469    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
2470    didn't scale.
2471
2472    The more traditional mega-struct containing architecture specific
2473    data for all the various GDB components was also considered.  Since
2474    GDB is built from a variable number of (fairly independent)

2486
2487    The INIT function takes two parameters: INFO which contains the

2490    ``struct gdbarch'' for this architecture.

2493    information obtained from INFO.ABFD or the previously selected
2494    architecture.
2495
2496    The ARCHES parameter is a linked list (sorted most recently used)
2497    of all the previously created architures for this architecture
2498    family.  The (possibly NULL) ARCHES->gdbarch can used to access
2499    values from the previously selected architecture for this
2500    architecture family.  The global ``current_gdbarch'' shall not be
2501    used.
2502
2503    The INIT function shall return any of: NULL - indicating that it
2504    doesn't recognize the selected architecture; an existing ``struct
2505    gdbarch'' from the ARCHES list - indicating that the new
2506    architecture is just a synonym for an earlier architecture (see
2507    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
2508    - that describes the selected architecture (see gdbarch_alloc()).
2509
2510    The DUMP_TDEP function shall print out all target specific values.
