926 | architecture. | |
927 | ||
928 | GDB targets (*-tdep.c) can register an interest in a specific | |
929 | architecture. Other GDB components can register a need to maintain | |
930 | per-architecture data. | |
931 | ||
932 | The mechanisms below ensures that there is only a loose connection | |

935 | to maintain architecture specific data with gdbarch. |
936 | ||
937 | Pragmatics: | |
938 | ||
939 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
940 | didn't scale. | |
941 | ||
942 | The more traditional mega-struct containing architecture specific | |
943 | data for all the various GDB components was also considered. Since | |
0fa6923a | 944 | GDB is built from a variable number of (fairly independent) |
104c1213 JM |

950 | ||
951 | Register support for the specified ARCHITECTURE with GDB. When | |
952 | gdbarch determines that the specified architecture has been | |
953 | selected, the corresponding INIT function is called. | |
954 | ||
955 | -- | |
956 | ||
957 | The INIT function takes two parameters: INFO which contains the | |
958 | information available to gdbarch about the (possibly new) | |

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

7a107747 | 963 | information obtained from INFO.ABFD or the global defaults. |
0f79675b AC |
964 | |
965 | The ARCHES parameter is a linked list (sorted most recently used) | |
966 | of all the previously created architures for this architecture | |
967 | family. The (possibly NULL) ARCHES->gdbarch can used to access | |
968 | values from the previously selected architecture for this | |
969 | architecture family. The global \`\`current_gdbarch'' shall not be | |
970 | used. | |
104c1213 JM |

972 | The INIT function shall return any of: NULL - indicating that it | |

104c1213 JM |
974 | gdbarch'' from the ARCHES list - indicating that the new |
975 | architecture is just a synonym for an earlier architecture (see | |
976 | gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch'' | |
4b9b3959 AC |
