940 | ||
941 | GDB targets (*-tdep.c) can register an interest in a specific | |
942 | architecture. Other GDB components can register a need to maintain | |
943 | per-architecture data. | |
944 | ||

104c1213 JM |
948 | to maintain architecture specific data with gdbarch. |
949 | ||
950 | Pragmatics: | |
951 | ||
952 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
953 | didn't scale. | |
954 | ||
955 | The more traditional mega-struct containing architecture specific | |
956 | data for all the various GDB components was also considered. Since | |
0fa6923a | 957 | GDB is built from a variable number of (fairly independent) |
104c1213 JM |
958 | components it was determined that the global aproach was not |

963 | ||
964 | Register support for the specified ARCHITECTURE with GDB. When | |
965 | gdbarch determines that the specified architecture has been | |
966 | selected, the corresponding INIT function is called. | |
967 | ||
968 | -- | |
969 | ||
970 | The INIT function takes two parameters: INFO which contains the | |
971 | information available to gdbarch about the (possibly new) | |
972 | architecture; ARCHES which is a list of the previously created | |
973 | \`\`struct gdbarch'' for this architecture. | |
974 | ||
0f79675b AC |
975 | The INFO parameter is, as far as possible, be pre-initialized with |
976 | information obtained from INFO.ABFD or the previously selected | |
977 | architecture. | |
978 | ||
979 | The ARCHES parameter is a linked list (sorted most recently used) | |
980 | of all the previously created architures for this architecture | |
981 | family. The (possibly NULL) ARCHES->gdbarch can used to access | |
982 | values from the previously selected architecture for this | |
983 | architecture family. The global \`\`current_gdbarch'' shall not be | |
984 | used. | |
104c1213 JM |
985 | |
986 | The INIT function shall return any of: NULL - indicating that it | |
ec3d358c | 987 | doesn't recognize the selected architecture; an existing \`\`struct |
104c1213 JM |
988 | gdbarch'' from the ARCHES list - indicating that the new |
989 | architecture is just a synonym for an earlier architecture (see | |
990 | gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch'' | |
4b9b3959 AC |
991 | - that describes the selected architecture (see gdbarch_alloc()). |
992 | ||
993 | The DUMP_TDEP function shall print out all target specific values. | |
