2450
2451    GDB targets (*-tdep.c) can register an interest in a specific
2452    architecture.  Other GDB components can register a need to maintain
2453    per-architecture data.
2454
2455    The mechanisms below ensures that there is only a loose connection
2456    between the set-architecture command and the various GDB
2457    components.  Each component can independently register their need
2458    to maintain architecture specific data with gdbarch.
2459
2460    Pragmatics:
2461
2462    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
2463    didn't scale.
2464
2465    The more traditional mega-struct containing architecture specific
2466    data for all the various GDB components was also considered.  Since
2467    GDB is built from a variable number of (fairly independent)

2477

2479
2480    The INIT function takes two parameters: INFO which contains the
2481    information available to gdbarch about the (possibly new)
2482    architecture; ARCHES which is a list of the previously created
2483    ``struct gdbarch'' for this architecture.

2486    information obtained from INFO.ABFD or the previously selected
2487    architecture.
2488
2489    The ARCHES parameter is a linked list (sorted most recently used)
2490    of all the previously created architures for this architecture
2491    family.  The (possibly NULL) ARCHES->gdbarch can used to access
2492    values from the previously selected architecture for this
2493    architecture family.  The global ``current_gdbarch'' shall not be
2494    used.
2495
2496    The INIT function shall return any of: NULL - indicating that it
2497    doesn't recognize the selected architecture; an existing ``struct
2498    gdbarch'' from the ARCHES list - indicating that the new
2499    architecture is just a synonym for an earlier architecture (see
2500    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
2501    - that describes the selected architecture (see gdbarch_alloc()).
2502
2503    The DUMP_TDEP function shall print out all target specific values.
