1439    architecture.
1440
1441    GDB targets (*-tdep.c) can register an interest in a specific
1442    architecture.  Other GDB components can register a need to maintain
1443    per-architecture data.
1444
1445    The mechanisms below ensures that there is only a loose connection
1446    between the set-architecture command and the various GDB
1447    components.  Each component can independently register their need
1448    to maintain architecture specific data with gdbarch.
1449
1450    Pragmatics:
1451
1452    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1453    didn't scale.
1454
1455    The more traditional mega-struct containing architecture specific
1456    data for all the various GDB components was also considered.  Since
1457    GDB is built from a variable number of (fairly independent)
1458    components it was determined that the global aproach was not
1459    applicable. */

1462 /* Register a new architectural family with GDB.
1463
1464    Register support for the specified ARCHITECTURE with GDB.  When
1465    gdbarch determines that the specified architecture has been
1466    selected, the corresponding INIT function is called.
1467
1468    --
1469
1470    The INIT function takes two parameters: INFO which contains the
1471    information available to gdbarch about the (possibly new)
1472    architecture; ARCHES which is a list of the previously created
1473    ``struct gdbarch'' for this architecture.
1474
1475    The INIT function parameter INFO shall, as far as possible, be
1476    pre-initialized with information obtained from INFO.ABFD or
1477    previously selected architecture (if similar).  INIT shall ensure
1478    that the INFO.BYTE_ORDER is non-zero.
1479
1480    The INIT function shall return any of: NULL - indicating that it
1481    doesn't recognize the selected architecture; an existing ``struct
1482    gdbarch'' from the ARCHES list - indicating that the new
1483    architecture is just a synonym for an earlier architecture (see
1484    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
1485    - that describes the selected architecture (see gdbarch_alloc()).
1486
1487    The DUMP_TDEP function shall print out all target specific values.
1488    Care should be taken to ensure that the function works in both the
1489    multi-arch and non- multi-arch cases. */
