1654    GDB targets (*-tdep.c) can register an interest in a specific
1655    architecture.  Other GDB components can register a need to maintain
1656    per-architecture data.
1657

1659    between the set-architecture command and the various GDB
1660    components.  Each component can independently register their need
1661    to maintain architecture specific data with gdbarch.
1662
1663    Pragmatics:
1664
1665    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1666    didn't scale.
1667
1668    The more traditional mega-struct containing architecture specific
1669    data for all the various GDB components was also considered.  Since
1670    GDB is built from a variable number of (fairly independent)
1671    components it was determined that the global aproach was not

1691    that the INFO.BYTE_ORDER is non-zero.

1693    The INIT function shall return any of: NULL - indicating that it
1694    doesn't recognize the selected architecture; an existing ``struct
1695    gdbarch'' from the ARCHES list - indicating that the new
1696    architecture is just a synonym for an earlier architecture (see
1697    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
1698    - that describes the selected architecture (see gdbarch_alloc()).
1699
