1016 /* Mechanism for co-ordinating the selection of a specific
1017    architecture.
1018
1019    GDB targets (*-tdep.c) can register an interest in a specific
1020    architecture.  Other GDB components can register a need to maintain
1021    per-architecture data.
1022
1023    The mechanisms below ensures that there is only a loose connection
1024    between the set-architecture command and the various GDB
1025    components.  Each component can independently register their need
1026    to maintain architecture specific data with gdbarch.
1027
1028    Pragmatics:
1029
1030    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1031    didn't scale.
1032
1033    The more traditional mega-struct containing architecture specific
1034    data for all the various GDB components was also considered.  Since
1035    GDB is built from a variable number of (fairly independent)
1036    components it was determined that the global aproach was not
1037    applicable. */
1038
1039
1040 /* Register a new architectural family with GDB.
1041
1042    Register support for the specified ARCHITECTURE with GDB.  When
1043    gdbarch determines that the specified architecture has been
1044    selected, the corresponding INIT function is called.
1045
1046    --
1047
1048    The INIT function takes two parameters: INFO which contains the
1049    information available to gdbarch about the (possibly new)
1050    architecture; ARCHES which is a list of the previously created
1051    \`\`struct gdbarch'' for this architecture.
1052
1053    The INFO parameter is, as far as possible, be pre-initialized with
1054    information obtained from INFO.ABFD or the previously selected
1055    architecture.
1056
1057    The ARCHES parameter is a linked list (sorted most recently used)
1058    of all the previously created architures for this architecture
1059    family.  The (possibly NULL) ARCHES->gdbarch can used to access
1060    values from the previously selected architecture for this
1061    architecture family.  The global \`\`current_gdbarch'' shall not be
1062    used.
1063
1064    The INIT function shall return any of: NULL - indicating that it
1065    doesn't recognize the selected architecture; an existing \`\`struct
1066    gdbarch'' from the ARCHES list - indicating that the new
1067    architecture is just a synonym for an earlier architecture (see
1068    gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch''
1069    - that describes the selected architecture (see gdbarch_alloc()).
1070
1071    The DUMP_TDEP function shall print out all target specific values.
1072    Care should be taken to ensure that the function works in both the
1073    multi-arch and non- multi-arch cases. */
