1470    GDB targets (*-tdep.c) can register an interest in a specific
1471    architecture.  Other GDB components can register a need to maintain
1472    per-architecture data.
1473
1474    The mechanisms below ensures that there is only a loose connection
1475    between the set-architecture command and the various GDB
1476    components.  Each component can independently register their need
1477    to maintain architecture specific data with gdbarch.
1478
1479    Pragmatics:
1480
1481    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1482    didn't scale.
1483
1484    The more traditional mega-struct containing architecture specific
1485    data for all the various GDB components was also considered.  Since
1486    GDB is built from a variable number of (fairly independent)
1487    components it was determined that the global aproach was not
1488    applicable. */

1499    The INIT function takes two parameters: INFO which contains the
1500    information available to gdbarch about the (possibly new)
1501    architecture; ARCHES which is a list of the previously created
1502    ``struct gdbarch'' for this architecture.
1503
1504    The INIT function parameter INFO shall, as far as possible, be
1505    pre-initialized with information obtained from INFO.ABFD or
1506    previously selected architecture (if similar).  INIT shall ensure
1507    that the INFO.BYTE_ORDER is non-zero.
1508
1509    The INIT function shall return any of: NULL - indicating that it
1510    doesn't recognize the selected architecture; an existing ``struct
1511    gdbarch'' from the ARCHES list - indicating that the new
1512    architecture is just a synonym for an earlier architecture (see
1513    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
1514    - that describes the selected architecture (see gdbarch_alloc()).
1515
1516    The DUMP_TDEP function shall print out all target specific values.
1517    Care should be taken to ensure that the function works in both the
1518    multi-arch and non- multi-arch cases. */
