1016/* Mechanism for co-ordinating the selection of a specific
1017 architecture.
1018
1019 GDB targets (*-tdep.c) can register an interest in a specific
1020 architecture. Other GDB components can register a need to maintain
1021 per-architecture data.
1022
1023 The mechanisms below ensures that there is only a loose connection
1024 between the set-architecture command and the various GDB
0fa6923a 1025 components. Each component can independently register their need
104c1213
JM
1026 to maintain architecture specific data with gdbarch.
1027
1028 Pragmatics:
1029
1030 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
1031 didn't scale.
1032
1033 The more traditional mega-struct containing architecture specific
1034 data for all the various GDB components was also considered. Since
0fa6923a 1035 GDB is built from a variable number of (fairly independent)
104c1213
JM
1036 components it was determined that the global aproach was not
1037 applicable. */

1040/* Register a new architectural family with GDB.
1041
1042 Register support for the specified ARCHITECTURE with GDB. When
1043 gdbarch determines that the specified architecture has been
1044 selected, the corresponding INIT function is called.
1045
1046 --
1047
1048 The INIT function takes two parameters: INFO which contains the
1049 information available to gdbarch about the (possibly new)
1050 architecture; ARCHES which is a list of the previously created
1051 \`\`struct gdbarch'' for this architecture.
1052
0f79675b
AC
1053 The INFO parameter is, as far as possible, be pre-initialized with
1054 information obtained from INFO.ABFD or the previously selected
1055 architecture.
1056
1057 The ARCHES parameter is a linked list (sorted most recently used)
1058 of all the previously created architures for this architecture
1059 family. The (possibly NULL) ARCHES->gdbarch can used to access
1060 values from the previously selected architecture for this
1061 architecture family. The global \`\`current_gdbarch'' shall not be
1062 used.
104c1213
JM
1063
1064 The INIT function shall return any of: NULL - indicating that it
ec3d358c 1065 doesn't recognize the selected architecture; an existing \`\`struct
104c1213
JM
1066 gdbarch'' from the ARCHES list - indicating that the new
1067 architecture is just a synonym for an earlier architecture (see
1068 gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch''
4b9b3959
AC
1069 - that describes the selected architecture (see gdbarch_alloc()).
1070
1071 The DUMP_TDEP function shall print out all target specific values.
1072 Care should be taken to ensure that the function works in both the
1073 multi-arch and non- multi-arch cases. */
