1291/* Mechanism for co-ordinating the selection of a specific
1292 architecture.
1293
1294 GDB targets (*-tdep.c) can register an interest in a specific
1295 architecture. Other GDB components can register a need to maintain
1296 per-architecture data.
1297
1298 The mechanisms below ensures that there is only a loose connection
1299 between the set-architecture command and the various GDB
1300 components. Each component can independantly register their need
1301 to maintain architecture specific data with gdbarch.
1302
1303 Pragmatics:
1304
1305 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
1306 didn't scale.
1307
1308 The more traditional mega-struct containing architecture specific
1309 data for all the various GDB components was also considered. Since
1310 GDB is built from a variable number of (fairly independant)
1311 components it was determined that the global aproach was not
1312 applicable. */
1313
1314
1315/* Register a new architectural family with GDB.
1316
1317 Register support for the specified ARCHITECTURE with GDB. When
1318 gdbarch determines that the specified architecture has been
1319 selected, the corresponding INIT function is called.
1320
1321 --
1322
1323 The INIT function takes two parameters: INFO which contains the
1324 information available to gdbarch about the (possibly new)
1325 architecture; ARCHES which is a list of the previously created
1326 ``struct gdbarch'' for this architecture.
1327
1328 The INIT function parameter INFO shall, as far as possible, be
1329 pre-initialized with information obtained from INFO.ABFD or
1330 previously selected architecture (if similar). INIT shall ensure
1331 that the INFO.BYTE_ORDER is non-zero.
1332
1333 The INIT function shall return any of: NULL - indicating that it
1334 doesn't reconize the selected architecture; an existing ``struct
1335 gdbarch'' from the ARCHES list - indicating that the new
1336 architecture is just a synonym for an earlier architecture (see
1337 gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
4b9b3959
AC		 1338 - that describes the selected architecture (see gdbarch_alloc()).
1339
1340 The DUMP_TDEP function shall print out all target specific values.
1341 Care should be taken to ensure that the function works in both the
1342 multi-arch and non- multi-arch cases. */
