1071    GDB targets (*-tdep.c) can register an interest in a specific
1072    architecture.  Other GDB components can register a need to maintain
1073    per-architecture data.
1074
1075    The mechanisms below ensures that there is only a loose connection
1076    between the set-architecture command and the various GDB
1077    components.  Each component can independantly register their need
1078    to maintain architecture specific data with gdbarch.
1079
1080    Pragmatics:
1081
1082    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1083    didn't scale.
1084
1085    The more traditional mega-struct containing architecture specific
1086    data for all the various GDB components was also considered.  Since
1087    GDB is built from a variable number of (fairly independant)
1088    components it was determined that the global aproach was not

1110    The INIT function shall return any of: NULL - indicating that it
1111    doesn't reconize the selected architecture; an existing ``struct
1112    gdbarch'' from the ARCHES list - indicating that the new
1113    architecture is just a synonym for an earlier architecture (see
