2425
2426 GDB targets (*-tdep.c) can register an interest in a specific
2427 architecture. Other GDB components can register a need to maintain
2428 per-architecture data.
2429
2430 The mechanisms below ensures that there is only a loose connection
2431 between the set-architecture command and the various GDB
2432 components. Each component can independently register their need
2433 to maintain architecture specific data with gdbarch.
2434
2435 Pragmatics:
2436
2437 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
2438 didn't scale.
2439
2440 The more traditional mega-struct containing architecture specific
2441 data for all the various GDB components was also considered. Since
2442 GDB is built from a variable number of (fairly independent)
2443 components it was determined that the global aproach was not

2451 selected, the corresponding INIT function is called.
2452
2453 --
2454
2455 The INIT function takes two parameters: INFO which contains the
2456 information available to gdbarch about the (possibly new)
2457 architecture; ARCHES which is a list of the previously created
2458 ``struct gdbarch'' for this architecture.
2459
2460 The INFO parameter is, as far as possible, be pre-initialized with
2461 information obtained from INFO.ABFD or the previously selected
2462 architecture.
2463
2464 The ARCHES parameter is a linked list (sorted most recently used)
2465 of all the previously created architures for this architecture
2466 family. The (possibly NULL) ARCHES->gdbarch can used to access
2467 values from the previously selected architecture for this
2468 architecture family. The global ``current_gdbarch'' shall not be
2469 used.
2470
2471 The INIT function shall return any of: NULL - indicating that it
2472 doesn't recognize the selected architecture; an existing ``struct
2473 gdbarch'' from the ARCHES list - indicating that the new
2474 architecture is just a synonym for an earlier architecture (see
2475 gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
2476 - that describes the selected architecture (see gdbarch_alloc()).
2477
2478 The DUMP_TDEP function shall print out all target specific values.
2479 Care should be taken to ensure that the function works in both the
