 802 /* Mechanism for co-ordinating the selection of a specific
 803    architecture.
 804
 805    GDB targets (*-tdep.c) can register an interest in a specific
 806    architecture.  Other GDB components can register a need to maintain
 807    per-architecture data.
 808
 809    The mechanisms below ensures that there is only a loose connection
 810    between the set-architecture command and the various GDB
 811    components.  Each component can independantly register their need
 812    to maintain architecture specific data with gdbarch.
 813
 814    Pragmatics:
 815
 816    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
 817    didn't scale.
 818
 819    The more traditional mega-struct containing architecture specific
 820    data for all the various GDB components was also considered.  Since
 821    GDB is built from a variable number of (fairly independant)
 822    components it was determined that the global aproach was not
 823    applicable. */
