1036 /* Mechanism for co-ordinating the selection of a specific
1037    architecture.
1038
1039    GDB targets (*-tdep.c) can register an interest in a specific
1040    architecture.  Other GDB components can register a need to maintain
1041    per-architecture data.
1042
1043    The mechanisms below ensures that there is only a loose connection
1044    between the set-architecture command and the various GDB
1045    components.  Each component can independently register their need
1046    to maintain architecture specific data with gdbarch.
1047
1048    Pragmatics:
1049
1050    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1051    didn't scale.
1052
1053    The more traditional mega-struct containing architecture specific
1054    data for all the various GDB components was also considered.  Since
1055    GDB is built from a variable number of (fairly independent)
1056    components it was determined that the global aproach was not
1057    applicable. */
1058
1059
1060 /* Register a new architectural family with GDB.
1061
1062    Register support for the specified ARCHITECTURE with GDB.  When
1063    gdbarch determines that the specified architecture has been
1064    selected, the corresponding INIT function is called.
1065
1066    --
1067
1068    The INIT function takes two parameters: INFO which contains the
1069    information available to gdbarch about the (possibly new)
1070    architecture; ARCHES which is a list of the previously created
1071    \`\`struct gdbarch'' for this architecture.
1072
1073    The INFO parameter is, as far as possible, be pre-initialized with
1074    information obtained from INFO.ABFD or the previously selected
1075    architecture.
1076
1077    The ARCHES parameter is a linked list (sorted most recently used)
1078    of all the previously created architures for this architecture
1079    family.  The (possibly NULL) ARCHES->gdbarch can used to access
1080    values from the previously selected architecture for this
1081    architecture family.  The global \`\`current_gdbarch'' shall not be
1082    used.
1083
1084    The INIT function shall return any of: NULL - indicating that it
1085    doesn't recognize the selected architecture; an existing \`\`struct
1086    gdbarch'' from the ARCHES list - indicating that the new
1087    architecture is just a synonym for an earlier architecture (see
1088    gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch''
1089    - that describes the selected architecture (see gdbarch_alloc()).
1090
1091    The DUMP_TDEP function shall print out all target specific values.
1092    Care should be taken to ensure that the function works in both the
1093    multi-arch and non- multi-arch cases. */
