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. | |

1410 | architecture. | |
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 | |
99e7bb18 | 1418 | components. Each component can independently register their need |
0f71a2f6 JM |
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 | |
99e7bb18 | 1428 | GDB is built from a variable number of (fairly independent) |
0f71a2f6 JM |
1429 | components it was determined that the global aproach was not |

1434 | ||
1435 | Register support for the specified ARCHITECTURE with GDB. When | |
1436 | gdbarch determines that the specified architecture has been | |
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 | ||
0f79675b AC |
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. | |
0f71a2f6 JM |
1456 | |
1457 | The INIT function shall return any of: NULL - indicating that it | |
ec3d358c | 1458 | doesn't recognize the selected architecture; an existing ``struct |
0f71a2f6 JM |
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'' | |
4b9b3959 AC |
1462 | - that describes the selected architecture (see gdbarch_alloc()). |
1463 | ||
