1035 /* Mechanism for co-ordinating the selection of a specific
1036    architecture.
1037
1038    GDB targets (*-tdep.c) can register an interest in a specific
1039    architecture.  Other GDB components can register a need to maintain
1040    per-architecture data.
1041
1042    The mechanisms below ensures that there is only a loose connection
1043    between the set-architecture command and the various GDB
1044    components.  Each component can independently register their need
1045    to maintain architecture specific data with gdbarch.
1046
1047    Pragmatics:
1048
1049    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1050    didn't scale.
1051
1052    The more traditional mega-struct containing architecture specific
1053    data for all the various GDB components was also considered.  Since
1054    GDB is built from a variable number of (fairly independent)
1055    components it was determined that the global aproach was not
1056    applicable. */
1057
1058
1059 /* Register a new architectural family with GDB.
1060
1061    Register support for the specified ARCHITECTURE with GDB.  When
1062    gdbarch determines that the specified architecture has been
1063    selected, the corresponding INIT function is called.
1064
1065    --
1066
1067    The INIT function takes two parameters: INFO which contains the
1068    information available to gdbarch about the (possibly new)
1069    architecture; ARCHES which is a list of the previously created
1070    \`\`struct gdbarch'' for this architecture.
1071
1072    The INFO parameter is, as far as possible, be pre-initialized with
1073    information obtained from INFO.ABFD or the previously selected
1074    architecture.
1075
1076    The ARCHES parameter is a linked list (sorted most recently used)
1077    of all the previously created architures for this architecture
1078    family.  The (possibly NULL) ARCHES->gdbarch can used to access
1079    values from the previously selected architecture for this
1080    architecture family.  The global \`\`current_gdbarch'' shall not be
1081    used.
1082
1083    The INIT function shall return any of: NULL - indicating that it
1084    doesn't recognize the selected architecture; an existing \`\`struct
1085    gdbarch'' from the ARCHES list - indicating that the new
1086    architecture is just a synonym for an earlier architecture (see
1087    gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch''
1088    - that describes the selected architecture (see gdbarch_alloc()).
1089
1090    The DUMP_TDEP function shall print out all target specific values.
1091    Care should be taken to ensure that the function works in both the
1092    multi-arch and non- multi-arch cases. */
