1019/* Mechanism for co-ordinating the selection of a specific
1020 architecture.
1021
1022 GDB targets (*-tdep.c) can register an interest in a specific
1023 architecture. Other GDB components can register a need to maintain
1024 per-architecture data.
1025
1026 The mechanisms below ensures that there is only a loose connection
1027 between the set-architecture command and the various GDB
0fa6923a 1028 components. Each component can independently register their need
104c1213
JM
1029 to maintain architecture specific data with gdbarch.
1030
1031 Pragmatics:
1032
1033 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
1034 didn't scale.
1035
1036 The more traditional mega-struct containing architecture specific
1037 data for all the various GDB components was also considered. Since
0fa6923a 1038 GDB is built from a variable number of (fairly independent)
104c1213
JM
1039 components it was determined that the global aproach was not
1040 applicable. */

1044
1045 Register support for the specified ARCHITECTURE with GDB. When
1046 gdbarch determines that the specified architecture has been
1047 selected, the corresponding INIT function is called.
1048
1049 --
1050
1051 The INIT function takes two parameters: INFO which contains the
1052 information available to gdbarch about the (possibly new)
1053 architecture; ARCHES which is a list of the previously created
1054 \`\`struct gdbarch'' for this architecture.
1055
0f79675b
AC
1056 The INFO parameter is, as far as possible, be pre-initialized with
1057 information obtained from INFO.ABFD or the previously selected
1058 architecture.
1059
1060 The ARCHES parameter is a linked list (sorted most recently used)
1061 of all the previously created architures for this architecture
1062 family. The (possibly NULL) ARCHES->gdbarch can used to access
1063 values from the previously selected architecture for this
1064 architecture family. The global \`\`current_gdbarch'' shall not be
1065 used.
104c1213
JM
1066
1067 The INIT function shall return any of: NULL - indicating that it
ec3d358c 1068 doesn't recognize the selected architecture; an existing \`\`struct
104c1213
JM
1069 gdbarch'' from the ARCHES list - indicating that the new
1070 architecture is just a synonym for an earlier architecture (see
1071 gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch''
4b9b3959
AC
1072 - that describes the selected architecture (see gdbarch_alloc()).
1073
1074 The DUMP_TDEP function shall print out all target specific values.
1075 Care should be taken to ensure that the function works in both the
1076 multi-arch and non- multi-arch cases. */
