1200/* Mechanism for co-ordinating the selection of a specific

1202
1203 GDB targets (*-tdep.c) can register an interest in a specific
1204 architecture. Other GDB components can register a need to maintain
1205 per-architecture data.
1206
1207 The mechanisms below ensures that there is only a loose connection
1208 between the set-architecture command and the various GDB
1209 components. Each component can independantly register their need
1210 to maintain architecture specific data with gdbarch.

1214 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
1215 didn't scale.
1216
1217 The more traditional mega-struct containing architecture specific
1218 data for all the various GDB components was also considered. Since
1219 GDB is built from a variable number of (fairly independant)
1220 components it was determined that the global aproach was not
1221 applicable. */

1224/* Register a new architectural family with GDB.
1225
1226 Register support for the specified ARCHITECTURE with GDB. When
1227 gdbarch determines that the specified architecture has been
1228 selected, the corresponding INIT function is called.
1229
1230 --
1231
1232 The INIT function takes two parameters: INFO which contains the
1233 information available to gdbarch about the (possibly new)
1234 architecture; ARCHES which is a list of the previously created
1235 ``struct gdbarch'' for this architecture.
1236
1237 The INIT function parameter INFO shall, as far as possible, be
1238 pre-initialized with information obtained from INFO.ABFD or
1239 previously selected architecture (if similar). INIT shall ensure
1240 that the INFO.BYTE_ORDER is non-zero.
1241
1242 The INIT function shall return any of: NULL - indicating that it
1243 doesn't reconize the selected architecture; an existing ``struct
1244 gdbarch'' from the ARCHES list - indicating that the new
1245 architecture is just a synonym for an earlier architecture (see
1246 gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
4b9b3959
AC		 1247 - that describes the selected architecture (see gdbarch_alloc()).
1248
1249 The DUMP_TDEP function shall print out all target specific values.
1250 Care should be taken to ensure that the function works in both the
1251 multi-arch and non- multi-arch cases. */
