896 | Pragmatics: | |
897 | ||
898 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
899 | didn't scale. | |
900 | ||
901 | The more traditional mega-struct containing architecture specific | |
902 | data for all the various GDB components was also considered. Since | |
99e7bb18 | 903 | GDB is built from a variable number of (fairly independent) |
0f71a2f6 JM |

912 | selected, the corresponding INIT function is called. | |
913 | ||
914 | -- | |
915 | ||
916 | The INIT function takes two parameters: INFO which contains the | |
917 | information available to gdbarch about the (possibly new) | |

7a107747 | 922 | information obtained from INFO.ABFD or the global defaults. |
0f79675b AC |
923 | |
924 | The ARCHES parameter is a linked list (sorted most recently used) | |
925 | of all the previously created architures for this architecture | |
926 | family. The (possibly NULL) ARCHES->gdbarch can used to access | |

ec3d358c | 932 | doesn't recognize the selected architecture; an existing ``struct |
0f71a2f6 JM |
933 | gdbarch'' from the ARCHES list - indicating that the new |
934 | architecture is just a synonym for an earlier architecture (see | |
935 | gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch'' | |
4b9b3959 AC |
