2720
2721    GDB targets (*-tdep.c) can register an interest in a specific
2722    architecture.  Other GDB components can register a need to maintain
2723    per-architecture data.
2724
2725    The mechanisms below ensures that there is only a loose connection
2726    between the set-architecture command and the various GDB
2727    components.  Each component can independently register their need
2728    to maintain architecture specific data with gdbarch.
2729
2730    Pragmatics:
2731
2732    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
2733    didn't scale.
2734
2735    The more traditional mega-struct containing architecture specific
2736    data for all the various GDB components was also considered.  Since
2737    GDB is built from a variable number of (fairly independent)
2738    components it was determined that the global aproach was not
2739    applicable. */

2744    Register support for the specified ARCHITECTURE with GDB.  When

2746    selected, the corresponding INIT function is called.
2747
2748    --
2749
2750    The INIT function takes two parameters: INFO which contains the
2751    information available to gdbarch about the (possibly new)
2752    architecture; ARCHES which is a list of the previously created
2753    ``struct gdbarch'' for this architecture.
2754
2755    The INFO parameter is, as far as possible, be pre-initialized with
2756    information obtained from INFO.ABFD or the previously selected
2757    architecture.
2758
2759    The ARCHES parameter is a linked list (sorted most recently used)
2760    of all the previously created architures for this architecture
2761    family.  The (possibly NULL) ARCHES->gdbarch can used to access
2762    values from the previously selected architecture for this
2763    architecture family.  The global ``current_gdbarch'' shall not be
2764    used.
2765
2766    The INIT function shall return any of: NULL - indicating that it
2767    doesn't recognize the selected architecture; an existing ``struct
2768    gdbarch'' from the ARCHES list - indicating that the new
2769    architecture is just a synonym for an earlier architecture (see
2770    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
2771    - that describes the selected architecture (see gdbarch_alloc()).
2772
2773    The DUMP_TDEP function shall print out all target specific values.
2774    Care should be taken to ensure that the function works in both the
2775    multi-arch and non- multi-arch cases. */
