970 | /* Mechanism for co-ordinating the selection of a specific | |
971 | architecture. | |
972 | ||
973 | GDB targets (*-tdep.c) can register an interest in a specific | |
974 | architecture. Other GDB components can register a need to maintain | |
975 | per-architecture data. | |
976 | ||
977 | The mechanisms below ensures that there is only a loose connection | |
978 | between the set-architecture command and the various GDB | |
0fa6923a | 979 | components. Each component can independently register their need |
104c1213 JM |
980 | to maintain architecture specific data with gdbarch. |
981 | ||
982 | Pragmatics: | |
983 | ||
984 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
985 | didn't scale. | |
986 | ||
987 | The more traditional mega-struct containing architecture specific | |
988 | data for all the various GDB components was also considered. Since | |
0fa6923a | 989 | GDB is built from a variable number of (fairly independent) |
104c1213 JM |
990 | components it was determined that the global aproach was not |
991 | applicable. */ | |

993 | ||
994 | /* Register a new architectural family with GDB. | |
995 | ||
996 | Register support for the specified ARCHITECTURE with GDB. When | |
997 | gdbarch determines that the specified architecture has been | |
998 | selected, the corresponding INIT function is called. | |
999 | ||
1000 | -- | |
1001 | ||
1002 | The INIT function takes two parameters: INFO which contains the | |
1003 | information available to gdbarch about the (possibly new) | |
1004 | architecture; ARCHES which is a list of the previously created | |
1005 | \`\`struct gdbarch'' for this architecture. | |
1006 | ||
0f79675b AC |
1007 | The INFO parameter is, as far as possible, be pre-initialized with |
1008 | information obtained from INFO.ABFD or the previously selected | |
1009 | architecture. | |
1010 | ||
1011 | The ARCHES parameter is a linked list (sorted most recently used) | |
1012 | of all the previously created architures for this architecture | |
1013 | family. The (possibly NULL) ARCHES->gdbarch can used to access | |
1014 | values from the previously selected architecture for this | |
1015 | architecture family. The global \`\`current_gdbarch'' shall not be | |
1016 | used. | |
104c1213 JM |
1017 | |
1018 | The INIT function shall return any of: NULL - indicating that it | |
ec3d358c | 1019 | doesn't recognize the selected architecture; an existing \`\`struct |
104c1213 JM |
1020 | gdbarch'' from the ARCHES list - indicating that the new |
1021 | architecture is just a synonym for an earlier architecture (see | |
1022 | gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch'' | |
4b9b3959 AC |
1023 | - that describes the selected architecture (see gdbarch_alloc()). |
1024 | ||
1025 | The DUMP_TDEP function shall print out all target specific values. | |
