1346
1347    GDB targets (*-tdep.c) can register an interest in a specific
1348    architecture.  Other GDB components can register a need to maintain
1349    per-architecture data.
1350
1351    The mechanisms below ensures that there is only a loose connection
1352    between the set-architecture command and the various GDB
1353    components.  Each component can independently register their need
1354    to maintain architecture specific data with gdbarch.
1355
1356    Pragmatics:
1357
1358    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1359    didn't scale.
1360
1361    The more traditional mega-struct containing architecture specific
1362    data for all the various GDB components was also considered.  Since
1363    GDB is built from a variable number of (fairly independent)
1364    components it was determined that the global aproach was not
1365    applicable. */

1382    pre-initialized with information obtained from INFO.ABFD or

1384    that the INFO.BYTE_ORDER is non-zero.
1385
1386    The INIT function shall return any of: NULL - indicating that it
1387    doesn't reconize the selected architecture; an existing ``struct
1388    gdbarch'' from the ARCHES list - indicating that the new
1389    architecture is just a synonym for an earlier architecture (see
1390    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
1391    - that describes the selected architecture (see gdbarch_alloc()).
1392
1393    The DUMP_TDEP function shall print out all target specific values.
