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.

1428 data for all the various GDB components was also considered. Since

1448 information obtained from INFO.ABFD or the previously selected
1449 architecture.

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
