1290 | per-architecture data. | |

1292 | The mechanisms below ensures that there is only a loose connection | |

0f71a2f6 JM |

1298 | ||
1299 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
1300 | didn't scale. | |
1301 | ||
1302 | The more traditional mega-struct containing architecture specific | |
1303 | data for all the various GDB components was also considered. Since | |
99e7bb18 | 1304 | GDB is built from a variable number of (fairly independent) |
0f71a2f6 JM |

1313 | selected, the corresponding INIT function is called. | |
1314 | ||
1315 | -- | |
1316 | ||
1317 | The INIT function takes two parameters: INFO which contains the | |
1318 | information available to gdbarch about the (possibly new) | |
1319 | architecture; ARCHES which is a list of the previously created | |

7a107747 | 1323 | information obtained from INFO.ABFD or the global defaults. |
0f79675b AC |
1324 | |
1325 | The ARCHES parameter is a linked list (sorted most recently used) | |
1326 | of all the previously created architures for this architecture | |
1327 | family. The (possibly NULL) ARCHES->gdbarch can used to access | |

ec3d358c | 1333 | doesn't recognize the selected architecture; an existing ``struct |
0f71a2f6 JM |
1334 | gdbarch'' from the ARCHES list - indicating that the new |
1335 | architecture is just a synonym for an earlier architecture (see | |
1336 | gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch'' | |
4b9b3959 AC |
