1025 | /* Mechanism for co-ordinating the selection of a specific | |
1026 | architecture. | |
1027 | ||
1028 | GDB targets (*-tdep.c) can register an interest in a specific | |
1029 | architecture. Other GDB components can register a need to maintain | |
1030 | per-architecture data. | |
1031 | ||
1032 | The mechanisms below ensures that there is only a loose connection | |
1033 | between the set-architecture command and the various GDB | |
0fa6923a | 1034 | components. Each component can independently register their need |
104c1213 JM |
1035 | to maintain architecture specific data with gdbarch. |
1036 | ||
1037 | Pragmatics: | |
1038 | ||
1039 | Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It | |
1040 | didn't scale. | |
1041 | ||
1042 | The more traditional mega-struct containing architecture specific | |
1043 | data for all the various GDB components was also considered. Since | |
0fa6923a | 1044 | GDB is built from a variable number of (fairly independent) |
104c1213 JM |
1045 | components it was determined that the global aproach was not |

1050 | ||
1051 | Register support for the specified ARCHITECTURE with GDB. When | |
1052 | gdbarch determines that the specified architecture has been | |
1053 | selected, the corresponding INIT function is called. | |
1054 | ||
1055 | -- | |
1056 | ||
1057 | The INIT function takes two parameters: INFO which contains the | |
1058 | information available to gdbarch about the (possibly new) | |
1059 | architecture; ARCHES which is a list of the previously created | |
1060 | \`\`struct gdbarch'' for this architecture. | |
1061 | ||
0f79675b AC |
1062 | The INFO parameter is, as far as possible, be pre-initialized with |
1063 | information obtained from INFO.ABFD or the previously selected | |
1064 | architecture. | |
1065 | ||
1066 | The ARCHES parameter is a linked list (sorted most recently used) | |
1067 | of all the previously created architures for this architecture | |
1068 | family. The (possibly NULL) ARCHES->gdbarch can used to access | |
1069 | values from the previously selected architecture for this | |
1070 | architecture family. The global \`\`current_gdbarch'' shall not be | |
1071 | used. | |
104c1213 JM |
1072 | |
1073 | The INIT function shall return any of: NULL - indicating that it | |
ec3d358c | 1074 | doesn't recognize the selected architecture; an existing \`\`struct |
104c1213 JM |
1075 | gdbarch'' from the ARCHES list - indicating that the new |
1076 | architecture is just a synonym for an earlier architecture (see | |
1077 | gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch'' | |
4b9b3959 AC |
1078 | - that describes the selected architecture (see gdbarch_alloc()). |
1079 | ||
