901 | GDB targets (*-tdep.c) can register an interest in a specific | |

903 | per-architecture data. | |

913 | didn't scale. | |
914 | ||
915 | The more traditional mega-struct containing architecture specific | |

0fa6923a | 917 | GDB is built from a variable number of (fairly independent) |

926 | selected, the corresponding INIT function is called. | |
927 | ||
928 | -- | |
929 | ||
930 | The INIT function takes two parameters: INFO which contains the | |
931 | information available to gdbarch about the (possibly new) | |

933 | \`\`struct gdbarch'' for this architecture. | |

7a107747 | 936 | information obtained from INFO.ABFD or the global defaults. |
0f79675b AC |
937 | |
938 | The ARCHES parameter is a linked list (sorted most recently used) | |
939 | of all the previously created architures for this architecture | |
940 | family. The (possibly NULL) ARCHES->gdbarch can used to access | |

942 | architecture family. The global \`\`current_gdbarch'' shall not be | |

947 | gdbarch'' from the ARCHES list - indicating that the new |
948 | architecture is just a synonym for an earlier architecture (see | |
949 | gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch'' | |
4b9b3959 AC |
