956 | architecture. | |
957 | ||
958 | GDB targets (*-tdep.c) can register an interest in a specific | |
959 | architecture. Other GDB components can register a need to maintain | |
960 | per-architecture data. | |
961 | ||
962 | The mechanisms below ensures that there is only a loose connection | |
963 | between the set-architecture command and the various GDB | |
0fa6923a | 964 | components. Each component can independently register their need |
104c1213 JM |
965 | to maintain architecture specific data with gdbarch. |
966 | ||
967 | Pragmatics: | |
968 | ||
969 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
970 | didn't scale. | |
971 | ||
972 | The more traditional mega-struct containing architecture specific | |
973 | data for all the various GDB components was also considered. Since | |
0fa6923a | 974 | GDB is built from a variable number of (fairly independent) |
104c1213 JM |
975 | components it was determined that the global aproach was not |

980 | ||
981 | Register support for the specified ARCHITECTURE with GDB. When | |
982 | gdbarch determines that the specified architecture has been | |
983 | selected, the corresponding INIT function is called. | |
984 | ||
985 | -- | |
986 | ||
987 | The INIT function takes two parameters: INFO which contains the | |
988 | information available to gdbarch about the (possibly new) | |
989 | architecture; ARCHES which is a list of the previously created | |
990 | \`\`struct gdbarch'' for this architecture. | |

0f79675b AC |
992 | The INFO parameter is, as far as possible, be pre-initialized with |
993 | information obtained from INFO.ABFD or the previously selected | |
994 | architecture. | |
995 | ||
996 | The ARCHES parameter is a linked list (sorted most recently used) | |
997 | of all the previously created architures for this architecture | |
998 | family. The (possibly NULL) ARCHES->gdbarch can used to access | |
999 | values from the previously selected architecture for this | |
1000 | architecture family. The global \`\`current_gdbarch'' shall not be | |
1001 | used. | |
