872 | /* Mechanism for co-ordinating the selection of a specific | |
873 | architecture. | |
874 | ||
875 | GDB targets (*-tdep.c) can register an interest in a specific | |
876 | architecture. Other GDB components can register a need to maintain | |
877 | per-architecture data. | |
878 | ||
879 | The mechanisms below ensures that there is only a loose connection | |
880 | between the set-architecture command and the various GDB | |
99e7bb18 | 881 | components. Each component can independently register their need |
0f71a2f6 JM |
882 | to maintain architecture specific data with gdbarch. |
883 | ||
884 | Pragmatics: | |
885 | ||
886 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
887 | didn't scale. | |
888 | ||
889 | The more traditional mega-struct containing architecture specific | |
890 | data for all the various GDB components was also considered. Since | |
99e7bb18 | 891 | GDB is built from a variable number of (fairly independent) |
0f71a2f6 JM |
892 | components it was determined that the global aproach was not |
893 | applicable. */ | |

897 | ||
898 | Register support for the specified ARCHITECTURE with GDB. When | |
899 | gdbarch determines that the specified architecture has been | |
900 | selected, the corresponding INIT function is called. | |
901 | ||
902 | -- | |
903 | ||
904 | The INIT function takes two parameters: INFO which contains the | |
905 | information available to gdbarch about the (possibly new) | |
906 | architecture; ARCHES which is a list of the previously created | |
907 | ``struct gdbarch'' for this architecture. | |
908 | ||
0f79675b | 909 | The INFO parameter is, as far as possible, be pre-initialized with |
7a107747 | 910 | information obtained from INFO.ABFD or the global defaults. |
0f79675b AC |
911 | |
912 | The ARCHES parameter is a linked list (sorted most recently used) | |
913 | of all the previously created architures for this architecture | |
914 | family. The (possibly NULL) ARCHES->gdbarch can used to access | |
915 | values from the previously selected architecture for this | |
916 | architecture family. The global ``current_gdbarch'' shall not be | |
917 | used. | |
0f71a2f6 JM |
918 | |
919 | The INIT function shall return any of: NULL - indicating that it | |
ec3d358c | 920 | doesn't recognize the selected architecture; an existing ``struct |
0f71a2f6 JM |
921 | gdbarch'' from the ARCHES list - indicating that the new |
922 | architecture is just a synonym for an earlier architecture (see | |
923 | gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch'' | |
4b9b3959 AC |
924 | - that describes the selected architecture (see gdbarch_alloc()). |
925 | ||
