944 | ||
945 | GDB targets (*-tdep.c) can register an interest in a specific | |
946 | architecture. Other GDB components can register a need to maintain | |
947 | per-architecture data. | |
948 | ||
949 | The mechanisms below ensures that there is only a loose connection | |

104c1213 JM |
952 | to maintain architecture specific data with gdbarch. |
953 | ||
954 | Pragmatics: | |
955 | ||
956 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
957 | didn't scale. | |
958 | ||
959 | The more traditional mega-struct containing architecture specific | |
960 | data for all the various GDB components was also considered. Since | |
0fa6923a | 961 | GDB is built from a variable number of (fairly independent) |
104c1213 JM |
962 | components it was determined that the global aproach was not |

967 | ||
968 | Register support for the specified ARCHITECTURE with GDB. When | |
969 | gdbarch determines that the specified architecture has been | |
970 | selected, the corresponding INIT function is called. | |
971 | ||
972 | -- | |
973 | ||
974 | The INIT function takes two parameters: INFO which contains the | |
975 | information available to gdbarch about the (possibly new) | |
976 | architecture; ARCHES which is a list of the previously created | |
977 | \`\`struct gdbarch'' for this architecture. | |
978 | ||
0f79675b AC |
979 | The INFO parameter is, as far as possible, be pre-initialized with |
980 | information obtained from INFO.ABFD or the previously selected | |
981 | architecture. | |
982 | ||
983 | The ARCHES parameter is a linked list (sorted most recently used) | |
984 | of all the previously created architures for this architecture | |
985 | family. The (possibly NULL) ARCHES->gdbarch can used to access | |
986 | values from the previously selected architecture for this | |
987 | architecture family. The global \`\`current_gdbarch'' shall not be | |
988 | used. | |
104c1213 JM |
989 | |
990 | The INIT function shall return any of: NULL - indicating that it | |
ec3d358c | 991 | doesn't recognize the selected architecture; an existing \`\`struct |
104c1213 JM |
992 | gdbarch'' from the ARCHES list - indicating that the new |
993 | architecture is just a synonym for an earlier architecture (see | |
994 | gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch'' | |
4b9b3959 AC |
995 | - that describes the selected architecture (see gdbarch_alloc()). |
996 | ||
997 | The DUMP_TDEP function shall print out all target specific values. | |
998 | Care should be taken to ensure that the function works in both the | |
