 766    the DEPRECATED_EXTRACT_STRUCT_VALUE implementation has been
 767    erreneous - the code was incorrectly assuming that the return-value
 768    address, stored in a register, was preserved across the entire
 769    function call.
 770    For the moment retain DEPRECATED_EXTRACT_STRUCT_VALUE as a marker of
 771    the ABIs that are still to be analyzed - perhaps this should simply
 772    be deleted.  The commented out extract_returned_value_address method
 773    is provided as a starting point for the 32-bit SPARC.  It, or
 774    something like it, along with changes to both infcmd.c and stack.c
 775    will be needed for that case to work.  NB: It is passed the callers
 776    frame since it is only after the callee has returned that this
 777    function is used.

1378    data for all the various GDB components was also considered.  Since

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.

1408    doesn't recognize the selected architecture; an existing ``struct
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''
1412    - that describes the selected architecture (see gdbarch_alloc()).
1413
