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

1390 | architecture. | |
1391 | ||
1392 | GDB targets (*-tdep.c) can register an interest in a specific | |
1393 | architecture. Other GDB components can register a need to maintain | |
1394 | per-architecture data. | |
1395 | ||
1396 | The mechanisms below ensures that there is only a loose connection | |
1397 | between the set-architecture command and the various GDB | |
99e7bb18 | 1398 | components. Each component can independently register their need |
0f71a2f6 JM |
1399 | to maintain architecture specific data with gdbarch. |
1400 | ||
1401 | Pragmatics: | |
1402 | ||
1403 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
1404 | didn't scale. | |
1405 | ||
1406 | The more traditional mega-struct containing architecture specific | |
1407 | data for all the various GDB components was also considered. Since | |
99e7bb18 | 1408 | GDB is built from a variable number of (fairly independent) |
0f71a2f6 JM |
1409 | components it was determined that the global aproach was not |

1415 | Register support for the specified ARCHITECTURE with GDB. When | |

1417 | selected, the corresponding INIT function is called. | |
1418 | ||
1419 | -- | |
1420 | ||
1421 | The INIT function takes two parameters: INFO which contains the | |
1422 | information available to gdbarch about the (possibly new) | |
1423 | architecture; ARCHES which is a list of the previously created | |

7a107747 | 1427 | information obtained from INFO.ABFD or the global defaults. |
0f79675b AC |
1428 | |
1429 | The ARCHES parameter is a linked list (sorted most recently used) | |
1430 | of all the previously created architures for this architecture | |
1431 | family. The (possibly NULL) ARCHES->gdbarch can used to access | |
1432 | values from the previously selected architecture for this | |
1433 | architecture family. The global ``current_gdbarch'' shall not be | |
1434 | used. | |
0f71a2f6 JM |
1435 | |
1436 | The INIT function shall return any of: NULL - indicating that it | |
ec3d358c | 1437 | doesn't recognize the selected architecture; an existing ``struct |
0f71a2f6 JM |
1438 | gdbarch'' from the ARCHES list - indicating that the new |
1439 | architecture is just a synonym for an earlier architecture (see | |
1440 | gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch'' | |
4b9b3959 AC |
1441 | - that describes the selected architecture (see gdbarch_alloc()). |
1442 | ||
