1456 Register support for the specified ARCHITECTURE with GDB. When
1457 gdbarch determines that the specified architecture has been
1458 selected, the corresponding INIT function is called.
1462 The INIT function takes two parameters: INFO which contains the
1463 information available to gdbarch about the (possibly new)
1464 architecture; ARCHES which is a list of the previously created
1465 ``struct gdbarch'' for this architecture.
1467 The INFO parameter is, as far as possible, be pre-initialized with
1468 information obtained from INFO.ABFD or the global defaults.
1470 The ARCHES parameter is a linked list (sorted most recently used)
1471 of all the previously created architures for this architecture
1472 family. The (possibly NULL) ARCHES->gdbarch can used to access
1473 values from the previously selected architecture for this
1474 architecture family.
1476 The INIT function shall return any of: NULL - indicating that it
1477 doesn't recognize the selected architecture; an existing ``struct
1478 gdbarch'' from the ARCHES list - indicating that the new
1479 architecture is just a synonym for an earlier architecture (see
1480 gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
1481 - that describes the selected architecture (see gdbarch_alloc()).
1483 The DUMP_TDEP function shall print out all target specific values.
1484 Care should be taken to ensure that the function works in both the
