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

810

818 gdbarch'' from the ARCHES list - indicating that the new
