1423    address in the callers frame).  All the other cases so far examined,
1424    the DEPRECATED_EXTRACT_STRUCT_VALUE implementation has been
1425    erreneous - the code was incorrectly assuming that the return-value

1427    function call.
1428    For the moment retain DEPRECATED_EXTRACT_STRUCT_VALUE as a marker of
1429    the ABIs that are still to be analyzed - perhaps this should simply
1430    be deleted.  The commented out extract_returned_value_address method

1432    something like it, along with changes to both infcmd.c and stack.c
1433    will be needed for that case to work.  NB: It is passed the callers

2225
2226    GDB targets (*-tdep.c) can register an interest in a specific
2227    architecture.  Other GDB components can register a need to maintain
2228    per-architecture data.
2229
2230    The mechanisms below ensures that there is only a loose connection
2231    between the set-architecture command and the various GDB
2232    components.  Each component can independently register their need
2233    to maintain architecture specific data with gdbarch.
2234
2235    Pragmatics:
2236
2237    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
2238    didn't scale.
2239
2240    The more traditional mega-struct containing architecture specific
2241    data for all the various GDB components was also considered.  Since
2242    GDB is built from a variable number of (fairly independent)
2243    components it was determined that the global aproach was not
2244    applicable. */

2249    Register support for the specified ARCHITECTURE with GDB.  When

2251    selected, the corresponding INIT function is called.
2252
2253    --
2254
2255    The INIT function takes two parameters: INFO which contains the
2256    information available to gdbarch about the (possibly new)
2257    architecture; ARCHES which is a list of the previously created
2258    ``struct gdbarch'' for this architecture.
2259
2260    The INFO parameter is, as far as possible, be pre-initialized with
2261    information obtained from INFO.ABFD or the previously selected
2262    architecture.
2263
2264    The ARCHES parameter is a linked list (sorted most recently used)
2265    of all the previously created architures for this architecture
2266    family.  The (possibly NULL) ARCHES->gdbarch can used to access
2267    values from the previously selected architecture for this
2268    architecture family.  The global ``current_gdbarch'' shall not be
2269    used.
2270
2271    The INIT function shall return any of: NULL - indicating that it
2272    doesn't recognize the selected architecture; an existing ``struct
2273    gdbarch'' from the ARCHES list - indicating that the new
2274    architecture is just a synonym for an earlier architecture (see
2275    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
2276    - that describes the selected architecture (see gdbarch_alloc()).
2277
2278    The DUMP_TDEP function shall print out all target specific values.
2279    Care should be taken to ensure that the function works in both the
2280    multi-arch and non- multi-arch cases. */
