1992    GDB targets (*-tdep.c) can register an interest in a specific

1994    per-architecture data.
1995

1997    between the set-architecture command and the various GDB

1999    to maintain architecture specific data with gdbarch.

2002
2003    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
2004    didn't scale.
2005
2006    The more traditional mega-struct containing architecture specific
2007    data for all the various GDB components was also considered.  Since
2008    GDB is built from a variable number of (fairly independent)

2029    that the INFO.BYTE_ORDER is non-zero.

2032    doesn't recognize the selected architecture; an existing ``struct
2033    gdbarch'' from the ARCHES list - indicating that the new
2034    architecture is just a synonym for an earlier architecture (see
2035    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
2036    - that describes the selected architecture (see gdbarch_alloc()).
2037
