1001 /* Mechanism for co-ordinating the selection of a specific
1002    architecture.
1003
1004    GDB targets (*-tdep.c) can register an interest in a specific
1005    architecture.  Other GDB components can register a need to maintain
1006    per-architecture data.
1007
1008    The mechanisms below ensures that there is only a loose connection
1009    between the set-architecture command and the various GDB
1010    components.  Each component can independently register their need
1011    to maintain architecture specific data with gdbarch.
1012
1013    Pragmatics:
1014
1015    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1016    didn't scale.
1017
1018    The more traditional mega-struct containing architecture specific
1019    data for all the various GDB components was also considered.  Since
1020    GDB is built from a variable number of (fairly independent)
1021    components it was determined that the global aproach was not
1022    applicable. */
1023
1024
1025 /* Register a new architectural family with GDB.
1026
1027    Register support for the specified ARCHITECTURE with GDB.  When
1028    gdbarch determines that the specified architecture has been
1029    selected, the corresponding INIT function is called.
1030
1031    --
1032
1033    The INIT function takes two parameters: INFO which contains the
1034    information available to gdbarch about the (possibly new)
1035    architecture; ARCHES which is a list of the previously created
1036    \`\`struct gdbarch'' for this architecture.
1037
1038    The INFO parameter is, as far as possible, be pre-initialized with
1039    information obtained from INFO.ABFD or the previously selected
1040    architecture.
1041
1042    The ARCHES parameter is a linked list (sorted most recently used)
1043    of all the previously created architures for this architecture
1044    family.  The (possibly NULL) ARCHES->gdbarch can used to access
1045    values from the previously selected architecture for this
1046    architecture family.  The global \`\`current_gdbarch'' shall not be
1047    used.
1048
1049    The INIT function shall return any of: NULL - indicating that it
1050    doesn't recognize the selected architecture; an existing \`\`struct
1051    gdbarch'' from the ARCHES list - indicating that the new
1052    architecture is just a synonym for an earlier architecture (see
1053    gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch''
1054    - that describes the selected architecture (see gdbarch_alloc()).
1055
1056    The DUMP_TDEP function shall print out all target specific values.
1057    Care should be taken to ensure that the function works in both the
1058    multi-arch and non- multi-arch cases. */
