1308    ABI suitable for the implementation of a robust extract
1309    struct-convention return-value address method (the sparc saves the
1310    address in the callers frame).  All the other cases so far examined,
1311    the DEPRECATED_EXTRACT_STRUCT_VALUE implementation has been
1312    erreneous - the code was incorrectly assuming that the return-value
1313    address, stored in a register, was preserved across the entire
1314    function call.
1315    For the moment retain DEPRECATED_EXTRACT_STRUCT_VALUE as a marker of
1316    the ABIs that are still to be analyzed - perhaps this should simply
1317    be deleted.  The commented out extract_returned_value_address method
1318    is provided as a starting point for the 32-bit SPARC.  It, or
1319    something like it, along with changes to both infcmd.c and stack.c
1320    will be needed for that case to work.  NB: It is passed the callers
1321    frame since it is only after the callee has returned that this

2101 /* Mechanism for co-ordinating the selection of a specific
2102    architecture.
2103
2104    GDB targets (*-tdep.c) can register an interest in a specific
2105    architecture.  Other GDB components can register a need to maintain
2106    per-architecture data.
2107
2108    The mechanisms below ensures that there is only a loose connection
2109    between the set-architecture command and the various GDB
2110    components.  Each component can independently register their need
2111    to maintain architecture specific data with gdbarch.
2112
2113    Pragmatics:
2114
2115    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
2116    didn't scale.
2117
2118    The more traditional mega-struct containing architecture specific
2119    data for all the various GDB components was also considered.  Since
2120    GDB is built from a variable number of (fairly independent)
2121    components it was determined that the global aproach was not
2122    applicable. */

2125 /* Register a new architectural family with GDB.
2126
2127    Register support for the specified ARCHITECTURE with GDB.  When
2128    gdbarch determines that the specified architecture has been
2129    selected, the corresponding INIT function is called.
2130
2131    --
2132
2133    The INIT function takes two parameters: INFO which contains the
2134    information available to gdbarch about the (possibly new)
2135    architecture; ARCHES which is a list of the previously created
2136    ``struct gdbarch'' for this architecture.
2137
2138    The INFO parameter is, as far as possible, be pre-initialized with
2139    information obtained from INFO.ABFD or the previously selected
2140    architecture.
2141
2142    The ARCHES parameter is a linked list (sorted most recently used)
2143    of all the previously created architures for this architecture
2144    family.  The (possibly NULL) ARCHES->gdbarch can used to access
2145    values from the previously selected architecture for this
2146    architecture family.  The global ``current_gdbarch'' shall not be
2147    used.
2148
2149    The INIT function shall return any of: NULL - indicating that it
2150    doesn't recognize the selected architecture; an existing ``struct
2151    gdbarch'' from the ARCHES list - indicating that the new
2152    architecture is just a synonym for an earlier architecture (see
2153    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
2154    - that describes the selected architecture (see gdbarch_alloc()).
2155
2156    The DUMP_TDEP function shall print out all target specific values.
2157    Care should be taken to ensure that the function works in both the
2158    multi-arch and non- multi-arch cases. */
