1007 /* Mechanism for co-ordinating the selection of a specific
1008    architecture.
1009
1010    GDB targets (*-tdep.c) can register an interest in a specific
1011    architecture.  Other GDB components can register a need to maintain
1012    per-architecture data.
1013
1014    The mechanisms below ensures that there is only a loose connection
1015    between the set-architecture command and the various GDB
1016    components.  Each component can independently register their need
1017    to maintain architecture specific data with gdbarch.
1018
1019    Pragmatics:
1020
1021    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1022    didn't scale.
1023
1024    The more traditional mega-struct containing architecture specific
1025    data for all the various GDB components was also considered.  Since
1026    GDB is built from a variable number of (fairly independent)
1027    components it was determined that the global aproach was not
1028    applicable. */

1031 /* Register a new architectural family with GDB.
1032
1033    Register support for the specified ARCHITECTURE with GDB.  When
1034    gdbarch determines that the specified architecture has been
1035    selected, the corresponding INIT function is called.
1036
1037    --
1038
1039    The INIT function takes two parameters: INFO which contains the
1040    information available to gdbarch about the (possibly new)
1041    architecture; ARCHES which is a list of the previously created
1042    \`\`struct gdbarch'' for this architecture.
1043
1044    The INFO parameter is, as far as possible, be pre-initialized with
1045    information obtained from INFO.ABFD or the previously selected
1046    architecture.
1047
1048    The ARCHES parameter is a linked list (sorted most recently used)
1049    of all the previously created architures for this architecture
1050    family.  The (possibly NULL) ARCHES->gdbarch can used to access
1051    values from the previously selected architecture for this
1052    architecture family.  The global \`\`current_gdbarch'' shall not be
1053    used.
1054
1055    The INIT function shall return any of: NULL - indicating that it
1056    doesn't recognize the selected architecture; an existing \`\`struct
1057    gdbarch'' from the ARCHES list - indicating that the new
1058    architecture is just a synonym for an earlier architecture (see
1059    gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch''
1060    - that describes the selected architecture (see gdbarch_alloc()).
1061
1062    The DUMP_TDEP function shall print out all target specific values.
1063    Care should be taken to ensure that the function works in both the
1064    multi-arch and non- multi-arch cases. */
