1004 /* Mechanism for co-ordinating the selection of a specific
1005    architecture.
1006
1007    GDB targets (*-tdep.c) can register an interest in a specific
1008    architecture.  Other GDB components can register a need to maintain
1009    per-architecture data.
1010
1011    The mechanisms below ensures that there is only a loose connection
1012    between the set-architecture command and the various GDB
1013    components.  Each component can independently register their need
1014    to maintain architecture specific data with gdbarch.
1015
1016    Pragmatics:
1017
1018    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1019    didn't scale.
1020
1021    The more traditional mega-struct containing architecture specific
1022    data for all the various GDB components was also considered.  Since
1023    GDB is built from a variable number of (fairly independent)
1024    components it was determined that the global aproach was not
1025    applicable. */
1026
1027
1028 /* Register a new architectural family with GDB.
1029
1030    Register support for the specified ARCHITECTURE with GDB.  When
1031    gdbarch determines that the specified architecture has been
1032    selected, the corresponding INIT function is called.
1033
1034    --
1035
1036    The INIT function takes two parameters: INFO which contains the
1037    information available to gdbarch about the (possibly new)
1038    architecture; ARCHES which is a list of the previously created
1039    \`\`struct gdbarch'' for this architecture.
1040
1041    The INFO parameter is, as far as possible, be pre-initialized with
1042    information obtained from INFO.ABFD or the previously selected
1043    architecture.
1044
1045    The ARCHES parameter is a linked list (sorted most recently used)
1046    of all the previously created architures for this architecture
1047    family.  The (possibly NULL) ARCHES->gdbarch can used to access
1048    values from the previously selected architecture for this
1049    architecture family.  The global \`\`current_gdbarch'' shall not be
1050    used.
1051
1052    The INIT function shall return any of: NULL - indicating that it
1053    doesn't recognize the selected architecture; an existing \`\`struct
1054    gdbarch'' from the ARCHES list - indicating that the new
1055    architecture is just a synonym for an earlier architecture (see
1056    gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch''
1057    - that describes the selected architecture (see gdbarch_alloc()).
1058
1059    The DUMP_TDEP function shall print out all target specific values.
1060    Care should be taken to ensure that the function works in both the
1061    multi-arch and non- multi-arch cases. */
