1933    architecture.
1934
1935    GDB targets (*-tdep.c) can register an interest in a specific
1936    architecture.  Other GDB components can register a need to maintain
1937    per-architecture data.
1938
1939    The mechanisms below ensures that there is only a loose connection
1940    between the set-architecture command and the various GDB
1941    components.  Each component can independently register their need
1942    to maintain architecture specific data with gdbarch.
1943
1944    Pragmatics:
1945
1946    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1947    didn't scale.
1948
1949    The more traditional mega-struct containing architecture specific
1950    data for all the various GDB components was also considered.  Since
1951    GDB is built from a variable number of (fairly independent)
1952    components it was determined that the global aproach was not

1972    that the INFO.BYTE_ORDER is non-zero.

1974    The INIT function shall return any of: NULL - indicating that it
1975    doesn't recognize the selected architecture; an existing ``struct
1976    gdbarch'' from the ARCHES list - indicating that the new
1977    architecture is just a synonym for an earlier architecture (see
1978    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
1979    - that describes the selected architecture (see gdbarch_alloc()).
1980
