1972
1973    GDB targets (*-tdep.c) can register an interest in a specific
1974    architecture.  Other GDB components can register a need to maintain
1975    per-architecture data.
1976
1977    The mechanisms below ensures that there is only a loose connection
1978    between the set-architecture command and the various GDB
1979    components.  Each component can independently register their need
1980    to maintain architecture specific data with gdbarch.
1981
1982    Pragmatics:
1983
1984    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1985    didn't scale.
1986
1987    The more traditional mega-struct containing architecture specific
1988    data for all the various GDB components was also considered.  Since
1989    GDB is built from a variable number of (fairly independent)

2015    architecture is just a synonym for an earlier architecture (see
2016    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
2017    - that describes the selected architecture (see gdbarch_alloc()).
