823/* As of 2004-01-17 only the 32-bit SPARC ABI has been identified as an
824 ABI suitable for the implementation of a robust extract
825 struct-convention return-value address method (the sparc saves the
826 address in the callers frame). All the other cases so far examined,
827 the DEPRECATED_EXTRACT_STRUCT_VALUE implementation has been
828 erreneous - the code was incorrectly assuming that the return-value
829 address, stored in a register, was preserved across the entire
830 function call.
831 For the moment retain DEPRECATED_EXTRACT_STRUCT_VALUE as a marker of
832 the ABIs that are still to be analyzed - perhaps this should simply
833 be deleted. The commented out extract_returned_value_address method
834 is provided as a starting point for the 32-bit SPARC. It, or
835 something like it, along with changes to both infcmd.c and stack.c
836 will be needed for that case to work. NB: It is passed the callers
837 frame since it is only after the callee has returned that this
838 function is used.

1411
1412 GDB targets (*-tdep.c) can register an interest in a specific
1413 architecture. Other GDB components can register a need to maintain
1414 per-architecture data.
1415
1416 The mechanisms below ensures that there is only a loose connection
1417 between the set-architecture command and the various GDB
1418 components. Each component can independently register their need
1419 to maintain architecture specific data with gdbarch.
1420
1421 Pragmatics:
1422
1423 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
1424 didn't scale.
1425
1426 The more traditional mega-struct containing architecture specific
1427 data for all the various GDB components was also considered. Since
1428 GDB is built from a variable number of (fairly independent)
1429 components it was determined that the global aproach was not

1437 selected, the corresponding INIT function is called.
1438
1439 --
1440
1441 The INIT function takes two parameters: INFO which contains the
1442 information available to gdbarch about the (possibly new)
1443 architecture; ARCHES which is a list of the previously created
1444 ``struct gdbarch'' for this architecture.
1445
1446 The INFO parameter is, as far as possible, be pre-initialized with
1447 information obtained from INFO.ABFD or the previously selected
1448 architecture.
1449
1450 The ARCHES parameter is a linked list (sorted most recently used)
1451 of all the previously created architures for this architecture
1452 family. The (possibly NULL) ARCHES->gdbarch can used to access
1453 values from the previously selected architecture for this
1454 architecture family. The global ``current_gdbarch'' shall not be
1455 used.
1456
1457 The INIT function shall return any of: NULL - indicating that it
1458 doesn't recognize the selected architecture; an existing ``struct
1459 gdbarch'' from the ARCHES list - indicating that the new
1460 architecture is just a synonym for an earlier architecture (see
1461 gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
1462 - that describes the selected architecture (see gdbarch_alloc()).
1463
1464 The DUMP_TDEP function shall print out all target specific values.
1465 Care should be taken to ensure that the function works in both the
1466 multi-arch and non- multi-arch cases. */
