1318    GDB targets (*-tdep.c) can register an interest in a specific

1320    per-architecture data.
1321

1323    between the set-architecture command and the various GDB

1329    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1330    didn't scale.
1331
1332    The more traditional mega-struct containing architecture specific
1333    data for all the various GDB components was also considered.  Since
1334    GDB is built from a variable number of (fairly independent)

1344

1347    The INIT function takes two parameters: INFO which contains the

1349    architecture; ARCHES which is a list of the previously created
1350    ``struct gdbarch'' for this architecture.

1352    The INFO parameter is, as far as possible, be pre-initialized with
1353    information obtained from INFO.ABFD or the global defaults.
1354
1355    The ARCHES parameter is a linked list (sorted most recently used)
1356    of all the previously created architures for this architecture
1357    family.  The (possibly NULL) ARCHES->gdbarch can used to access
1358    values from the previously selected architecture for this
1359    architecture family.  The global ``current_gdbarch'' shall not be
1360    used.
1361
1362    The INIT function shall return any of: NULL - indicating that it
1363    doesn't recognize the selected architecture; an existing ``struct
1364    gdbarch'' from the ARCHES list - indicating that the new
1365    architecture is just a synonym for an earlier architecture (see
1366    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
1367    - that describes the selected architecture (see gdbarch_alloc()).
1368
1369    The DUMP_TDEP function shall print out all target specific values.
