851/* As of 2004-01-17 only the 32-bit SPARC ABI has been identified as an
852 ABI suitable for the implementation of a robust extract
853 struct-convention return-value address method (the sparc saves the
854 address in the callers frame). All the other cases so far examined,
855 the DEPRECATED_EXTRACT_STRUCT_VALUE implementation has been
856 erreneous - the code was incorrectly assuming that the return-value
857 address, stored in a register, was preserved across the entire
858 function call.
859 For the moment retain DEPRECATED_EXTRACT_STRUCT_VALUE as a marker of
860 the ABIs that are still to be analyzed - perhaps this should simply
861 be deleted. The commented out extract_returned_value_address method
862 is provided as a starting point for the 32-bit SPARC. It, or
863 something like it, along with changes to both infcmd.c and stack.c
864 will be needed for that case to work. NB: It is passed the callers
865 frame since it is only after the callee has returned that this
866 function is used.

1412
1413 GDB targets (*-tdep.c) can register an interest in a specific
1414 architecture. Other GDB components can register a need to maintain
1415 per-architecture data.
1416
1417 The mechanisms below ensures that there is only a loose connection
1418 between the set-architecture command and the various GDB
1419 components. Each component can independently register their need
1420 to maintain architecture specific data with gdbarch.
1421
1422 Pragmatics:
1423
1424 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
1425 didn't scale.
1426
1427 The more traditional mega-struct containing architecture specific
1428 data for all the various GDB components was also considered. Since
1429 GDB is built from a variable number of (fairly independent)
1430 components it was determined that the global aproach was not

1438 selected, the corresponding INIT function is called.
1439
1440 --
1441
1442 The INIT function takes two parameters: INFO which contains the
1443 information available to gdbarch about the (possibly new)
1444 architecture; ARCHES which is a list of the previously created
1445 ``struct gdbarch'' for this architecture.
1446
1447 The INFO parameter is, as far as possible, be pre-initialized with
1448 information obtained from INFO.ABFD or the previously selected
1449 architecture.
1450
1451 The ARCHES parameter is a linked list (sorted most recently used)
1452 of all the previously created architures for this architecture
1453 family. The (possibly NULL) ARCHES->gdbarch can used to access
1454 values from the previously selected architecture for this
1455 architecture family. The global ``current_gdbarch'' shall not be
1456 used.
1457
1458 The INIT function shall return any of: NULL - indicating that it
1459 doesn't recognize the selected architecture; an existing ``struct
1460 gdbarch'' from the ARCHES list - indicating that the new
1461 architecture is just a synonym for an earlier architecture (see
1462 gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
1463 - that describes the selected architecture (see gdbarch_alloc()).
1464
1465 The DUMP_TDEP function shall print out all target specific values.
1466 Care should be taken to ensure that the function works in both the
1467 multi-arch and non- multi-arch cases. */
