1393 | information available to gdbarch about the (possibly new) | |
1394 | architecture; ARCHES which is a list of the previously created | |
1395 | ``struct gdbarch'' for this architecture. | |
1396 | ||
0f79675b | 1397 | The INFO parameter is, as far as possible, be pre-initialized with |
7a107747 | 1398 | information obtained from INFO.ABFD or the global defaults. |
0f79675b AC |
1399 | |
1400 | The ARCHES parameter is a linked list (sorted most recently used) | |
1401 | of all the previously created architures for this architecture | |
1402 | family. The (possibly NULL) ARCHES->gdbarch can used to access | |
1403 | values from the previously selected architecture for this | |
1404 | architecture family. The global ``current_gdbarch'' shall not be | |
1405 | used. | |

ec3d358c | 1408 | doesn't recognize the selected architecture; an existing ``struct |
0f71a2f6 JM |
1409 | gdbarch'' from the ARCHES list - indicating that the new |
1410 | architecture is just a synonym for an earlier architecture (see | |
1411 | gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch'' | |
4b9b3959 AC |
1412 | - that describes the selected architecture (see gdbarch_alloc()). |
