1003 /* Mechanism for co-ordinating the selection of a specific
1004    architecture.
1005
1006    GDB targets (*-tdep.c) can register an interest in a specific
1007    architecture.  Other GDB components can register a need to maintain
1008    per-architecture data.
1009
1010    The mechanisms below ensures that there is only a loose connection
1011    between the set-architecture command and the various GDB
1012    components.  Each component can independently register their need
1013    to maintain architecture specific data with gdbarch.
1014
1015    Pragmatics:
1016
1017    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1018    didn't scale.
1019
1020    The more traditional mega-struct containing architecture specific
1021    data for all the various GDB components was also considered.  Since
1022    GDB is built from a variable number of (fairly independent)
1023    components it was determined that the global aproach was not
1024    applicable. */
1025
1026
1027 /* Register a new architectural family with GDB.
1028
1029    Register support for the specified ARCHITECTURE with GDB.  When
1030    gdbarch determines that the specified architecture has been
1031    selected, the corresponding INIT function is called.
1032
1033    --
1034
1035    The INIT function takes two parameters: INFO which contains the
1036    information available to gdbarch about the (possibly new)
1037    architecture; ARCHES which is a list of the previously created
1038    \`\`struct gdbarch'' for this architecture.
1039
1040    The INFO parameter is, as far as possible, be pre-initialized with
1041    information obtained from INFO.ABFD or the previously selected
1042    architecture.
1043
1044    The ARCHES parameter is a linked list (sorted most recently used)
1045    of all the previously created architures for this architecture
1046    family.  The (possibly NULL) ARCHES->gdbarch can used to access
1047    values from the previously selected architecture for this
1048    architecture family.  The global \`\`current_gdbarch'' shall not be
1049    used.
1050
1051    The INIT function shall return any of: NULL - indicating that it
1052    doesn't recognize the selected architecture; an existing \`\`struct
1053    gdbarch'' from the ARCHES list - indicating that the new
1054    architecture is just a synonym for an earlier architecture (see
1055    gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch''
1056    - that describes the selected architecture (see gdbarch_alloc()).
1057
1058    The DUMP_TDEP function shall print out all target specific values.
1059    Care should be taken to ensure that the function works in both the
1060    multi-arch and non- multi-arch cases. */
