 880    address in the callers frame).  All the other cases so far examined,

 882    erreneous - the code was incorrectly assuming that the return-value

 885    For the moment retain DEPRECATED_EXTRACT_STRUCT_VALUE as a marker of
 886    the ABIs that are still to be analyzed - perhaps this should simply
 887    be deleted.  The commented out extract_returned_value_address method
 888    is provided as a starting point for the 32-bit SPARC.  It, or
 889    something like it, along with changes to both infcmd.c and stack.c
 890    will be needed for that case to work.  NB: It is passed the callers
 891    frame since it is only after the callee has returned that this

1441 /* Mechanism for co-ordinating the selection of a specific
1442    architecture.
1443
1444    GDB targets (*-tdep.c) can register an interest in a specific
1445    architecture.  Other GDB components can register a need to maintain
1446    per-architecture data.
1447
1448    The mechanisms below ensures that there is only a loose connection
1449    between the set-architecture command and the various GDB
1450    components.  Each component can independently register their need
1451    to maintain architecture specific data with gdbarch.
1452
1453    Pragmatics:
1454
1455    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1456    didn't scale.
1457
1458    The more traditional mega-struct containing architecture specific
1459    data for all the various GDB components was also considered.  Since
1460    GDB is built from a variable number of (fairly independent)
1461    components it was determined that the global aproach was not
1462    applicable. */

1465 /* Register a new architectural family with GDB.
1466
1467    Register support for the specified ARCHITECTURE with GDB.  When
1468    gdbarch determines that the specified architecture has been
1469    selected, the corresponding INIT function is called.
1470
1471    --
1472
1473    The INIT function takes two parameters: INFO which contains the
1474    information available to gdbarch about the (possibly new)
1475    architecture; ARCHES which is a list of the previously created
1476    ``struct gdbarch'' for this architecture.
1477
1478    The INFO parameter is, as far as possible, be pre-initialized with
1479    information obtained from INFO.ABFD or the previously selected
1480    architecture.
1481
1482    The ARCHES parameter is a linked list (sorted most recently used)
1483    of all the previously created architures for this architecture
1484    family.  The (possibly NULL) ARCHES->gdbarch can used to access
1485    values from the previously selected architecture for this
1486    architecture family.  The global ``current_gdbarch'' shall not be
1487    used.
1488
1489    The INIT function shall return any of: NULL - indicating that it
1490    doesn't recognize the selected architecture; an existing ``struct
1491    gdbarch'' from the ARCHES list - indicating that the new
1492    architecture is just a synonym for an earlier architecture (see
1493    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
1494    - that describes the selected architecture (see gdbarch_alloc()).
1495
1496    The DUMP_TDEP function shall print out all target specific values.
1497    Care should be taken to ensure that the function works in both the
1498    multi-arch and non- multi-arch cases. */
