1288    GDB targets (*-tdep.c) can register an interest in a specific

1299    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1300    didn't scale.
1301
1302    The more traditional mega-struct containing architecture specific
1303    data for all the various GDB components was also considered.  Since
1304    GDB is built from a variable number of (fairly independent)

1317    The INIT function takes two parameters: INFO which contains the

1320    ``struct gdbarch'' for this architecture.

1322    The INFO parameter is, as far as possible, be pre-initialized with
1323    information obtained from INFO.ABFD or the global defaults.
1324
1325    The ARCHES parameter is a linked list (sorted most recently used)
1326    of all the previously created architures for this architecture
1327    family.  The (possibly NULL) ARCHES->gdbarch can used to access
1328    values from the previously selected architecture for this
1329    architecture family.  The global ``current_gdbarch'' shall not be
1330    used.
1331
1332    The INIT function shall return any of: NULL - indicating that it
1333    doesn't recognize the selected architecture; an existing ``struct
1334    gdbarch'' from the ARCHES list - indicating that the new
1335    architecture is just a synonym for an earlier architecture (see
1336    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
1337    - that describes the selected architecture (see gdbarch_alloc()).
1338
1339    The DUMP_TDEP function shall print out all target specific values.
