879 | architecture. | |
880 | ||
881 | GDB targets (*-tdep.c) can register an interest in a specific | |
882 | architecture. Other GDB components can register a need to maintain | |
883 | per-architecture data. | |
884 | ||
885 | The mechanisms below ensures that there is only a loose connection | |
886 | between the set-architecture command and the various GDB | |
99e7bb18 | 887 | components. Each component can independently register their need |
0f71a2f6 JM |
888 | to maintain architecture specific data with gdbarch. |
889 | ||
890 | Pragmatics: | |
891 | ||
892 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
893 | didn't scale. | |
894 | ||
895 | The more traditional mega-struct containing architecture specific | |
896 | data for all the various GDB components was also considered. Since | |
99e7bb18 | 897 | GDB is built from a variable number of (fairly independent) |
0f71a2f6 JM |
898 | components it was determined that the global aproach was not |
899 | applicable. */ | |

903 | ||
904 | Register support for the specified ARCHITECTURE with GDB. When | |
905 | gdbarch determines that the specified architecture has been | |
906 | selected, the corresponding INIT function is called. | |
907 | ||
908 | -- | |
909 | ||
910 | The INIT function takes two parameters: INFO which contains the | |
911 | information available to gdbarch about the (possibly new) | |
912 | architecture; ARCHES which is a list of the previously created | |
913 | ``struct gdbarch'' for this architecture. | |

0f79675b | 915 | The INFO parameter is, as far as possible, be pre-initialized with |
7a107747 | 916 | information obtained from INFO.ABFD or the global defaults. |
0f79675b AC |
917 | |
918 | The ARCHES parameter is a linked list (sorted most recently used) | |
919 | of all the previously created architures for this architecture | |
920 | family. The (possibly NULL) ARCHES->gdbarch can used to access | |
921 | values from the previously selected architecture for this | |
922 | architecture family. The global ``current_gdbarch'' shall not be | |
923 | used. | |
0f71a2f6 JM |
924 | |
925 | The INIT function shall return any of: NULL - indicating that it | |
ec3d358c | 926 | doesn't recognize the selected architecture; an existing ``struct |
0f71a2f6 JM |
927 | gdbarch'' from the ARCHES list - indicating that the new |
928 | architecture is just a synonym for an earlier architecture (see | |
929 | gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch'' | |
4b9b3959 AC |
930 | - that describes the selected architecture (see gdbarch_alloc()). |
931 | ||
