 820    architecture.
 821
 822    GDB targets (*-tdep.c) can register an interest in a specific
 823    architecture.  Other GDB components can register a need to maintain
 824    per-architecture data.
 825
 826    The mechanisms below ensures that there is only a loose connection
 827    between the set-architecture command and the various GDB
 828    components.  Each component can independantly register their need
 829    to maintain architecture specific data with gdbarch.
 830
 831    Pragmatics:
 832
 833    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
 834    didn't scale.
 835
 836    The more traditional mega-struct containing architecture specific
 837    data for all the various GDB components was also considered.  Since
 838    GDB is built from a variable number of (fairly independant)
 839    components it was determined that the global aproach was not
 840    applicable. */
