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

1370    didn't scale.

1373    data for all the various GDB components was also considered.  Since

1393    information obtained from INFO.ABFD or the global defaults.
1394

1396    of all the previously created architures for this architecture
1397    family.  The (possibly NULL) ARCHES->gdbarch can used to access
1398    values from the previously selected architecture for this
1399    architecture family.  The global ``current_gdbarch'' shall not be
1400    used.
1401
1402    The INIT function shall return any of: NULL - indicating that it
1403    doesn't recognize the selected architecture; an existing ``struct
1404    gdbarch'' from the ARCHES list - indicating that the new
1405    architecture is just a synonym for an earlier architecture (see
1406    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
1407    - that describes the selected architecture (see gdbarch_alloc()).
