1322    architecture.
1323
1324    GDB targets (*-tdep.c) can register an interest in a specific
1325    architecture.  Other GDB components can register a need to maintain
1326    per-architecture data.
1327
1328    The mechanisms below ensures that there is only a loose connection
1329    between the set-architecture command and the various GDB
1330    components.  Each component can independantly register their need
1331    to maintain architecture specific data with gdbarch.
1332
1333    Pragmatics:
1334
1335    Previously, a single TARGET_ARCHITECTURE_HOOK was provided.  It
1336    didn't scale.
1337
1338    The more traditional mega-struct containing architecture specific
1339    data for all the various GDB components was also considered.  Since
1340    GDB is built from a variable number of (fairly independant)
1341    components it was determined that the global aproach was not
1342    applicable. */

1356    ``struct gdbarch'' for this architecture.

1359    pre-initialized with information obtained from INFO.ABFD or

1361    that the INFO.BYTE_ORDER is non-zero.
1362
1363    The INIT function shall return any of: NULL - indicating that it
1364    doesn't reconize the selected architecture; an existing ``struct
1365    gdbarch'' from the ARCHES list - indicating that the new
1366    architecture is just a synonym for an earlier architecture (see
1367    gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
1368    - that describes the selected architecture (see gdbarch_alloc()).
1369
1370    The DUMP_TDEP function shall print out all target specific values.
