1176    architecture.
1177
1178    GDB targets (*-tdep.c) can register an interest in a specific
1179    architecture.  Other GDB components can register a need to maintain
1180    per-architecture data.
1181
1182    The mechanisms below ensures that there is only a loose connection
1183    between the set-architecture command and the various GDB
1184    components.  Each component can independently register their need
1185    to maintain architecture specific data with gdbarch.
1186
1187    Pragmatics:
1188
1189    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1190    didn't scale.
1191
1192    The more traditional mega-struct containing architecture specific
1193    data for all the various GDB components was also considered.  Since
1194    GDB is built from a variable number of (fairly independent)
1195    components it was determined that the global aproach was not
1196    applicable. */

1201    Register support for the specified ARCHITECTURE with GDB.  When

1203    selected, the corresponding INIT function is called.
1204
1205    --
1206
1207    The INIT function takes two parameters: INFO which contains the
1208    information available to gdbarch about the (possibly new)
1209    architecture; ARCHES which is a list of the previously created
1210    ``struct gdbarch'' for this architecture.
1211
1212    The INFO parameter is, as far as possible, be pre-initialized with
1213    information obtained from INFO.ABFD or the global defaults.
1214
1215    The ARCHES parameter is a linked list (sorted most recently used)
1216    of all the previously created architures for this architecture
1217    family.  The (possibly NULL) ARCHES->gdbarch can used to access
1218    values from the previously selected architecture for this
1219    architecture family.  The global ``current_gdbarch'' shall not be
1220    used.
1221
1222    The INIT function shall return any of: NULL - indicating that it
1223    doesn't recognize the selected architecture; an existing ``struct
1224    gdbarch'' from the ARCHES list - indicating that the new
1225    architecture is just a synonym for an earlier architecture (see
1226    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
1227    - that describes the selected architecture (see gdbarch_alloc()).
1228
1229    The DUMP_TDEP function shall print out all target specific values.
1230    Care should be taken to ensure that the function works in both the
1231    multi-arch and non- multi-arch cases. */
