1146
1147 GDB targets (*-tdep.c) can register an interest in a specific
1148 architecture. Other GDB components can register a need to maintain
1149 per-architecture data.
1150
1151 The mechanisms below ensures that there is only a loose connection
1152 between the set-architecture command and the various GDB
1153 components. Each component can independently register their need
1154 to maintain architecture specific data with gdbarch.
1155
1156 Pragmatics:
1157
1158 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
1159 didn't scale.
1160
1161 The more traditional mega-struct containing architecture specific
1162 data for all the various GDB components was also considered. Since
1163 GDB is built from a variable number of (fairly independent)
1164 components it was determined that the global aproach was not
1165 applicable. */

1172 selected, the corresponding INIT function is called.
1173
1174 --
1175
1176 The INIT function takes two parameters: INFO which contains the
1177 information available to gdbarch about the (possibly new)
1178 architecture; ARCHES which is a list of the previously created
1179 ``struct gdbarch'' for this architecture.
1180
1181 The INFO parameter is, as far as possible, be pre-initialized with
1182 information obtained from INFO.ABFD or the global defaults.
1183
1184 The ARCHES parameter is a linked list (sorted most recently used)
1185 of all the previously created architures for this architecture
1186 family. The (possibly NULL) ARCHES->gdbarch can used to access
1187 values from the previously selected architecture for this
1188 architecture family. The global ``current_gdbarch'' shall not be
1189 used.
1190
1191 The INIT function shall return any of: NULL - indicating that it
1192 doesn't recognize the selected architecture; an existing ``struct
1193 gdbarch'' from the ARCHES list - indicating that the new
1194 architecture is just a synonym for an earlier architecture (see
1195 gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
1196 - that describes the selected architecture (see gdbarch_alloc()).
1197
1198 The DUMP_TDEP function shall print out all target specific values.
1199 Care should be taken to ensure that the function works in both the
1200 multi-arch and non- multi-arch cases. */
