850 | architecture. | |
851 | ||
852 | GDB targets (*-tdep.c) can register an interest in a specific | |
853 | architecture. Other GDB components can register a need to maintain | |
854 | per-architecture data. | |
855 | ||
856 | The mechanisms below ensures that there is only a loose connection | |
857 | between the set-architecture command and the various GDB | |
99e7bb18 | 858 | components. Each component can independently register their need |
0f71a2f6 JM |
859 | to maintain architecture specific data with gdbarch. |
860 | ||
861 | Pragmatics: | |
862 | ||
863 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
864 | didn't scale. | |
865 | ||
866 | The more traditional mega-struct containing architecture specific | |
867 | data for all the various GDB components was also considered. Since | |
99e7bb18 | 868 | GDB is built from a variable number of (fairly independent) |
0f71a2f6 JM |
869 | components it was determined that the global aproach was not |

874 | ||
875 | Register support for the specified ARCHITECTURE with GDB. When | |
876 | gdbarch determines that the specified architecture has been | |
877 | selected, the corresponding INIT function is called. | |
878 | ||
879 | -- | |
880 | ||
881 | The INIT function takes two parameters: INFO which contains the | |
882 | information available to gdbarch about the (possibly new) | |
883 | architecture; ARCHES which is a list of the previously created | |
884 | ``struct gdbarch'' for this architecture. | |

7a107747 | 887 | information obtained from INFO.ABFD or the global defaults. |
0f79675b AC |
888 | |
889 | The ARCHES parameter is a linked list (sorted most recently used) | |
890 | of all the previously created architures for this architecture | |
891 | family. The (possibly NULL) ARCHES->gdbarch can used to access | |

893 | architecture family. The global ``current_gdbarch'' shall not be | |
894 | used. | |
0f71a2f6 JM |
895 | |
896 | The INIT function shall return any of: NULL - indicating that it | |
ec3d358c | 897 | doesn't recognize the selected architecture; an existing ``struct |
0f71a2f6 JM |
898 | gdbarch'' from the ARCHES list - indicating that the new |
899 | architecture is just a synonym for an earlier architecture (see | |
900 | gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch'' | |
4b9b3959 AC |
901 | - that describes the selected architecture (see gdbarch_alloc()). |
