2239 between the set-architecture command and the various GDB
2240 components. Each component can independently register their need
2241 to maintain architecture specific data with gdbarch.
2242
2243 Pragmatics:
2244
2245 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
2246 didn't scale.
2247
2248 The more traditional mega-struct containing architecture specific
2249 data for all the various GDB components was also considered. Since
2250 GDB is built from a variable number of (fairly independent)
2251 components it was determined that the global aproach was not
2252 applicable. */

2256
2257 Register support for the specified ARCHITECTURE with GDB. When
2258 gdbarch determines that the specified architecture has been
2259 selected, the corresponding INIT function is called.
2260
2261 --
2262
2263 The INIT function takes two parameters: INFO which contains the
2264 information available to gdbarch about the (possibly new)
2265 architecture; ARCHES which is a list of the previously created
2266 ``struct gdbarch'' for this architecture.
2267
2268 The INIT function parameter INFO shall, as far as possible, be
2269 pre-initialized with information obtained from INFO.ABFD or
2270 previously selected architecture (if similar).
2271
2272 The INIT function shall return any of: NULL - indicating that it
2273 doesn't recognize the selected architecture; an existing ``struct
2274 gdbarch'' from the ARCHES list - indicating that the new
2275 architecture is just a synonym for an earlier architecture (see
2276 gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
2277 - that describes the selected architecture (see gdbarch_alloc()).
2278
2279 The DUMP_TDEP function shall print out all target specific values.
2280 Care should be taken to ensure that the function works in both the
2281 multi-arch and non- multi-arch cases. */
