1414    address in the callers frame).  All the other cases so far examined,
1415    the DEPRECATED_EXTRACT_STRUCT_VALUE implementation has been
1416    erreneous - the code was incorrectly assuming that the return-value

1418    function call.
1419    For the moment retain DEPRECATED_EXTRACT_STRUCT_VALUE as a marker of
1420    the ABIs that are still to be analyzed - perhaps this should simply
1421    be deleted.  The commented out extract_returned_value_address method

1423    something like it, along with changes to both infcmd.c and stack.c
1424    will be needed for that case to work.  NB: It is passed the callers

2207
2208    GDB targets (*-tdep.c) can register an interest in a specific
2209    architecture.  Other GDB components can register a need to maintain
2210    per-architecture data.
2211
2212    The mechanisms below ensures that there is only a loose connection
2213    between the set-architecture command and the various GDB
2214    components.  Each component can independently register their need
2215    to maintain architecture specific data with gdbarch.
2216
2217    Pragmatics:
2218
2219    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
2220    didn't scale.
2221
2222    The more traditional mega-struct containing architecture specific
2223    data for all the various GDB components was also considered.  Since
2224    GDB is built from a variable number of (fairly independent)
2225    components it was determined that the global aproach was not

2233    selected, the corresponding INIT function is called.
2234

2236
2237    The INIT function takes two parameters: INFO which contains the
2238    information available to gdbarch about the (possibly new)
2239    architecture; ARCHES which is a list of the previously created
2240    ``struct gdbarch'' for this architecture.
2241
2242    The INFO parameter is, as far as possible, be pre-initialized with
2243    information obtained from INFO.ABFD or the previously selected
2244    architecture.
2245
2246    The ARCHES parameter is a linked list (sorted most recently used)
2247    of all the previously created architures for this architecture
2248    family.  The (possibly NULL) ARCHES->gdbarch can used to access
2249    values from the previously selected architecture for this
2250    architecture family.  The global ``current_gdbarch'' shall not be
2251    used.
2252
2253    The INIT function shall return any of: NULL - indicating that it
2254    doesn't recognize the selected architecture; an existing ``struct
2255    gdbarch'' from the ARCHES list - indicating that the new
2256    architecture is just a synonym for an earlier architecture (see
2257    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
2258    - that describes the selected architecture (see gdbarch_alloc()).
2259
2260    The DUMP_TDEP function shall print out all target specific values.
2261    Care should be taken to ensure that the function works in both the
