1971 architecture.
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)
1990 components it was determined that the global aproach was not
1991 applicable. */

2004 architecture; ARCHES which is a list of the previously created
2005 ``struct gdbarch'' for this architecture.
2006
2007 The INIT function parameter INFO shall, as far as possible, be
2008 pre-initialized with information obtained from INFO.ABFD or
2009 previously selected architecture (if similar). INIT shall ensure
2010 that the INFO.BYTE_ORDER is non-zero.
2011
2012 The INIT function shall return any of: NULL - indicating that it
2013 doesn't recognize the selected architecture; an existing ``struct
2014 gdbarch'' from the ARCHES list - indicating that the new
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()).
2018
2019 The DUMP_TDEP function shall print out all target specific values.
2020 Care should be taken to ensure that the function works in both the
