 846    architecture.
 847
 848    GDB targets (*-tdep.c) can register an interest in a specific
 849    architecture.  Other GDB components can register a need to maintain
 850    per-architecture data.
 851
 852    The mechanisms below ensures that there is only a loose connection
 853    between the set-architecture command and the various GDB
 854    components.  Each component can independantly register their need
 855    to maintain architecture specific data with gdbarch.
 856
 857    Pragmatics:
 858
 859    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
 860    didn't scale.
 861
 862    The more traditional mega-struct containing architecture specific
 863    data for all the various GDB components was also considered.  Since
 864    GDB is built from a variable number of (fairly independant)
 865    components it was determined that the global aproach was not
 866    applicable. */
