3037 /* Mechanism for co-ordinating the selection of a specific
3038    architecture.
3039
3040    GDB targets (*-tdep.c) can register an interest in a specific
3041    architecture.  Other GDB components can register a need to maintain
3042    per-architecture data.
3043
3044    The mechanisms below ensures that there is only a loose connection
3045    between the set-architecture command and the various GDB
3046    components.  Each component can independently register their need
3047    to maintain architecture specific data with gdbarch.
3048
3049    Pragmatics:
3050
3051    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
3052    didn't scale.
3053
3054    The more traditional mega-struct containing architecture specific
3055    data for all the various GDB components was also considered.  Since
3056    GDB is built from a variable number of (fairly independent)
3057    components it was determined that the global aproach was not
3058    applicable. */

3062
3063    Register support for the specified ARCHITECTURE with GDB.  When
3064    gdbarch determines that the specified architecture has been
3065    selected, the corresponding INIT function is called.
3066
3067    --
3068
3069    The INIT function takes two parameters: INFO which contains the
3070    information available to gdbarch about the (possibly new)
3071    architecture; ARCHES which is a list of the previously created
3072    ``struct gdbarch'' for this architecture.
3073
3074    The INFO parameter is, as far as possible, be pre-initialized with
3075    information obtained from INFO.ABFD or the previously selected
3076    architecture.
3077
3078    The ARCHES parameter is a linked list (sorted most recently used)
3079    of all the previously created architures for this architecture
3080    family.  The (possibly NULL) ARCHES->gdbarch can used to access
3081    values from the previously selected architecture for this
3082    architecture family.  The global ``current_gdbarch'' shall not be
3083    used.
3084
3085    The INIT function shall return any of: NULL - indicating that it
3086    doesn't recognize the selected architecture; an existing ``struct
3087    gdbarch'' from the ARCHES list - indicating that the new
3088    architecture is just a synonym for an earlier architecture (see
3089    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
3090    - that describes the selected architecture (see gdbarch_alloc()).
3091
3092    The DUMP_TDEP function shall print out all target specific values.
3093    Care should be taken to ensure that the function works in both the
3094    multi-arch and non- multi-arch cases. */
