1162 /* As of 2004-01-17 only the 32-bit SPARC ABI has been identified as an
1163    ABI suitable for the implementation of a robust extract
1164    struct-convention return-value address method (the sparc saves the
1165    address in the callers frame).  All the other cases so far examined,
1166    the DEPRECATED_EXTRACT_STRUCT_VALUE implementation has been
1167    erreneous - the code was incorrectly assuming that the return-value
1168    address, stored in a register, was preserved across the entire
1169    function call.
1170    For the moment retain DEPRECATED_EXTRACT_STRUCT_VALUE as a marker of
1171    the ABIs that are still to be analyzed - perhaps this should simply
1172    be deleted.  The commented out extract_returned_value_address method
1173    is provided as a starting point for the 32-bit SPARC.  It, or
1174    something like it, along with changes to both infcmd.c and stack.c
1175    will be needed for that case to work.  NB: It is passed the callers
1176    frame since it is only after the callee has returned that this
1177    function is used.

1938    GDB targets (*-tdep.c) can register an interest in a specific

1949    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1950    didn't scale.
1951
1952    The more traditional mega-struct containing architecture specific
1953    data for all the various GDB components was also considered.  Since
1954    GDB is built from a variable number of (fairly independent)

1967    The INIT function takes two parameters: INFO which contains the

1970    ``struct gdbarch'' for this architecture.

1973    information obtained from INFO.ABFD or the previously selected
1974    architecture.
1975
1976    The ARCHES parameter is a linked list (sorted most recently used)
1977    of all the previously created architures for this architecture
1978    family.  The (possibly NULL) ARCHES->gdbarch can used to access
1979    values from the previously selected architecture for this
1980    architecture family.  The global ``current_gdbarch'' shall not be
1981    used.
1982
1983    The INIT function shall return any of: NULL - indicating that it
1984    doesn't recognize the selected architecture; an existing ``struct
1985    gdbarch'' from the ARCHES list - indicating that the new
1986    architecture is just a synonym for an earlier architecture (see
1987    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
1988    - that describes the selected architecture (see gdbarch_alloc()).
1989
1990    The DUMP_TDEP function shall print out all target specific values.
