886 | architecture. | |
887 | ||
888 | GDB targets (*-tdep.c) can register an interest in a specific | |
889 | architecture. Other GDB components can register a need to maintain | |
890 | per-architecture data. | |
891 | ||

897 | Pragmatics: | |
898 | ||
899 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
900 | didn't scale. | |
901 | ||
902 | The more traditional mega-struct containing architecture specific | |
903 | data for all the various GDB components was also considered. Since | |
0fa6923a | 904 | GDB is built from a variable number of (fairly independent) |
104c1213 JM |

910 | ||
911 | Register support for the specified ARCHITECTURE with GDB. When | |
912 | gdbarch determines that the specified architecture has been | |
913 | selected, the corresponding INIT function is called. | |
914 | ||
915 | -- | |
916 | ||
917 | The INIT function takes two parameters: INFO which contains the | |
918 | information available to gdbarch about the (possibly new) | |
919 | architecture; ARCHES which is a list of the previously created | |
920 | \`\`struct gdbarch'' for this architecture. | |

0f79675b | 922 | The INFO parameter is, as far as possible, be pre-initialized with |
7a107747 | 923 | information obtained from INFO.ABFD or the global defaults. |
0f79675b AC |
924 | |
925 | The ARCHES parameter is a linked list (sorted most recently used) | |
926 | of all the previously created architures for this architecture | |
927 | family. The (possibly NULL) ARCHES->gdbarch can used to access | |
928 | values from the previously selected architecture for this | |
929 | architecture family. The global \`\`current_gdbarch'' shall not be | |
930 | used. | |
104c1213 JM |

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

104c1213 JM |
934 | gdbarch'' from the ARCHES list - indicating that the new |
935 | architecture is just a synonym for an earlier architecture (see | |
936 | gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch'' | |
4b9b3959 AC |
937 | - that describes the selected architecture (see gdbarch_alloc()). |
938 | ||
