 772 /* Mechanism for co-ordinating the selection of a specific
 773    architecture.
 774
 775    GDB targets (*-tdep.c) can register an interest in a specific
 776    architecture.  Other GDB components can register a need to maintain
 777    per-architecture data.
 778
 779    The mechanisms below ensures that there is only a loose connection
 780    between the set-architecture command and the various GDB
 781    components.  Each component can independantly register their need
 782    to maintain architecture specific data with gdbarch.
 783
 784    Pragmatics:
 785
 786    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
 787    didn't scale.
 788
 789    The more traditional mega-struct containing architecture specific
 790    data for all the various GDB components was also considered.  Since
 791    GDB is built from a variable number of (fairly independant)
 792    components it was determined that the global aproach was not
 793    applicable. */
