1256 | architecture. | |
1257 | ||
1258 | GDB targets (*-tdep.c) can register an interest in a specific | |
1259 | architecture. Other GDB components can register a need to maintain | |
1260 | per-architecture data. | |
1261 | ||
1262 | The mechanisms below ensures that there is only a loose connection | |
1263 | between the set-architecture command and the various GDB | |
99e7bb18 | 1264 | components. Each component can independently register their need |
0f71a2f6 JM |
1265 | to maintain architecture specific data with gdbarch. |
1266 | ||
1267 | Pragmatics: | |
1268 | ||
1269 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
1270 | didn't scale. | |
1271 | ||
1272 | The more traditional mega-struct containing architecture specific | |
1273 | data for all the various GDB components was also considered. Since | |
99e7bb18 | 1274 | GDB is built from a variable number of (fairly independent) |
0f71a2f6 JM |
1275 | components it was determined that the global aproach was not |

1280 | ||
1281 | Register support for the specified ARCHITECTURE with GDB. When | |
1282 | gdbarch determines that the specified architecture has been | |
1283 | selected, the corresponding INIT function is called. | |
1284 | ||
1285 | -- | |
1286 | ||
1287 | The INIT function takes two parameters: INFO which contains the | |
1288 | information available to gdbarch about the (possibly new) | |
1289 | architecture; ARCHES which is a list of the previously created | |
1290 | ``struct gdbarch'' for this architecture. | |
1291 | ||
0f79675b | 1292 | The INFO parameter is, as far as possible, be pre-initialized with |
7a107747 | 1293 | information obtained from INFO.ABFD or the global defaults. |
0f79675b AC |
1294 | |
1295 | The ARCHES parameter is a linked list (sorted most recently used) | |
1296 | of all the previously created architures for this architecture | |
1297 | family. The (possibly NULL) ARCHES->gdbarch can used to access | |
1298 | values from the previously selected architecture for this | |
1299 | architecture family. The global ``current_gdbarch'' shall not be | |
1300 | used. | |
0f71a2f6 JM |
1301 | |
1302 | The INIT function shall return any of: NULL - indicating that it | |
ec3d358c | 1303 | doesn't recognize the selected architecture; an existing ``struct |
0f71a2f6 JM |
1304 | gdbarch'' from the ARCHES list - indicating that the new |
1305 | architecture is just a synonym for an earlier architecture (see | |
1306 | gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch'' | |
4b9b3959 AC |
1307 | - that describes the selected architecture (see gdbarch_alloc()). |
