 788 /* As of 2004-01-17 only the 32-bit SPARC ABI has been identified as an
 789    ABI suitable for the implementation of a robust extract
 790    struct-convention return-value address method (the sparc saves the
 791    address in the callers frame).  All the other cases so far examined,
 792    the DEPRECATED_EXTRACT_STRUCT_VALUE implementation has been
 793    erreneous - the code was incorrectly assuming that the return-value
 794    address, stored in a register, was preserved across the entire
 795    function call.
 796    For the moment retain DEPRECATED_EXTRACT_STRUCT_VALUE as a marker of
 797    the ABIs that are still to be analyzed - perhaps this should simply
 798    be deleted.  The commented out extract_returned_value_address method
 799    is provided as a starting point for the 32-bit SPARC.  It, or
 800    something like it, along with changes to both infcmd.c and stack.c
 801    will be needed for that case to work.  NB: It is passed the callers
 802    frame since it is only after the callee has returned that this
 803    function is used.

1120    (as with rs6000).
1121
1122    FIXME/cagney/2001-01-18: The logic is backwards.  It should be asking if the
1123    target can single step.  If not, then implement single step using breakpoints.

1396    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1397    didn't scale.
1398

1400    data for all the various GDB components was also considered.  Since

1411
1412    --
1413
1414    The INIT function takes two parameters: INFO which contains the
1415    information available to gdbarch about the (possibly new)
1416    architecture; ARCHES which is a list of the previously created
1417    ``struct gdbarch'' for this architecture.

1419    The INFO parameter is, as far as possible, be pre-initialized with
1420    information obtained from INFO.ABFD or the global defaults.
1421
1422    The ARCHES parameter is a linked list (sorted most recently used)
1423    of all the previously created architures for this architecture
1424    family.  The (possibly NULL) ARCHES->gdbarch can used to access
1425    values from the previously selected architecture for this
1426    architecture family.  The global ``current_gdbarch'' shall not be
1427    used.
1428
1429    The INIT function shall return any of: NULL - indicating that it
1430    doesn't recognize the selected architecture; an existing ``struct
1431    gdbarch'' from the ARCHES list - indicating that the new
1432    architecture is just a synonym for an earlier architecture (see
1433    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
1434    - that describes the selected architecture (see gdbarch_alloc()).
1435
1436    The DUMP_TDEP function shall print out all target specific values.
