1006 /* Mechanism for co-ordinating the selection of a specific
1007    architecture.
1008
1009    GDB targets (*-tdep.c) can register an interest in a specific
1010    architecture.  Other GDB components can register a need to maintain
1011    per-architecture data.
1012
1013    The mechanisms below ensures that there is only a loose connection
1014    between the set-architecture command and the various GDB
1015    components.  Each component can independently register their need
1016    to maintain architecture specific data with gdbarch.
1017
1018    Pragmatics:
1019
1020    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1021    didn't scale.
1022
1023    The more traditional mega-struct containing architecture specific
1024    data for all the various GDB components was also considered.  Since
1025    GDB is built from a variable number of (fairly independent)
1026    components it was determined that the global aproach was not
1027    applicable. */

1030 /* Register a new architectural family with GDB.
1031
1032    Register support for the specified ARCHITECTURE with GDB.  When
1033    gdbarch determines that the specified architecture has been
1034    selected, the corresponding INIT function is called.
1035
1036    --
1037
1038    The INIT function takes two parameters: INFO which contains the
1039    information available to gdbarch about the (possibly new)
1040    architecture; ARCHES which is a list of the previously created
1041    \`\`struct gdbarch'' for this architecture.
1042
1043    The INFO parameter is, as far as possible, be pre-initialized with
1044    information obtained from INFO.ABFD or the previously selected
1045    architecture.
1046
1047    The ARCHES parameter is a linked list (sorted most recently used)
1048    of all the previously created architures for this architecture
1049    family.  The (possibly NULL) ARCHES->gdbarch can used to access
1050    values from the previously selected architecture for this
1051    architecture family.  The global \`\`current_gdbarch'' shall not be
1052    used.
1053
1054    The INIT function shall return any of: NULL - indicating that it
1055    doesn't recognize the selected architecture; an existing \`\`struct
1056    gdbarch'' from the ARCHES list - indicating that the new
1057    architecture is just a synonym for an earlier architecture (see
1058    gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch''
1059    - that describes the selected architecture (see gdbarch_alloc()).
1060
1061    The DUMP_TDEP function shall print out all target specific values.
1062    Care should be taken to ensure that the function works in both the
1063    multi-arch and non- multi-arch cases. */
