 811    architecture.
 812
 813    GDB targets (*-tdep.c) can register an interest in a specific
 814    architecture.  Other GDB components can register a need to maintain
 815    per-architecture data.
 816
 817    The mechanisms below ensures that there is only a loose connection
 818    between the set-architecture command and the various GDB
 819    components.  Each component can independantly register their need
 820    to maintain architecture specific data with gdbarch.
 821
 822    Pragmatics:
 823
 824    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
 825    didn't scale.
 826
 827    The more traditional mega-struct containing architecture specific
 828    data for all the various GDB components was also considered.  Since
 829    GDB is built from a variable number of (fairly independant)
 830    components it was determined that the global aproach was not
 831    applicable. */
