1257
1258    GDB targets (*-tdep.c) can register an interest in a specific
1259    architecture.  Other GDB components can register a need to maintain
1260    per-architecture data.
1261

1263    between the set-architecture command and the various GDB
1264    components.  Each component can independently register their need
1265    to maintain architecture specific data with gdbarch.
1266
1267    Pragmatics:
1268
1269    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1270    didn't scale.
1271
1272    The more traditional mega-struct containing architecture specific
1273    data for all the various GDB components was also considered.  Since
1274    GDB is built from a variable number of (fairly independent)
1275    components it was determined that the global aproach was not

1283    selected, the corresponding INIT function is called.
1284

1286
1287    The INIT function takes two parameters: INFO which contains the
1288    information available to gdbarch about the (possibly new)
1289    architecture; ARCHES which is a list of the previously created
1290    ``struct gdbarch'' for this architecture.

1292    The INFO parameter is, as far as possible, be pre-initialized with
1293    information obtained from INFO.ABFD or the global defaults.
1294
1295    The ARCHES parameter is a linked list (sorted most recently used)
1296    of all the previously created architures for this architecture
1297    family.  The (possibly NULL) ARCHES->gdbarch can used to access
1298    values from the previously selected architecture for this
1299    architecture family.  The global ``current_gdbarch'' shall not be
1300    used.
1301
1302    The INIT function shall return any of: NULL - indicating that it
1303    doesn't recognize the selected architecture; an existing ``struct
1304    gdbarch'' from the ARCHES list - indicating that the new
1305    architecture is just a synonym for an earlier architecture (see
1306    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
1307    - that describes the selected architecture (see gdbarch_alloc()).
1308
1309    The DUMP_TDEP function shall print out all target specific values.
