1000/* Mechanism for co-ordinating the selection of a specific
1001 architecture.
1002
1003 GDB targets (*-tdep.c) can register an interest in a specific
1004 architecture. Other GDB components can register a need to maintain
1005 per-architecture data.
1006
1007 The mechanisms below ensures that there is only a loose connection
1008 between the set-architecture command and the various GDB
0fa6923a 1009 components. Each component can independently register their need
104c1213
JM
1010 to maintain architecture specific data with gdbarch.
1011
1012 Pragmatics:
1013
1014 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
1015 didn't scale.
1016
1017 The more traditional mega-struct containing architecture specific
1018 data for all the various GDB components was also considered. Since
0fa6923a 1019 GDB is built from a variable number of (fairly independent)
104c1213
JM
1020 components it was determined that the global aproach was not
1021 applicable. */

1024/* Register a new architectural family with GDB.
1025
1026 Register support for the specified ARCHITECTURE with GDB. When
1027 gdbarch determines that the specified architecture has been
1028 selected, the corresponding INIT function is called.
1029
1030 --
1031
1032 The INIT function takes two parameters: INFO which contains the
1033 information available to gdbarch about the (possibly new)
1034 architecture; ARCHES which is a list of the previously created
1035 \`\`struct gdbarch'' for this architecture.
1036
0f79675b
AC
1037 The INFO parameter is, as far as possible, be pre-initialized with
1038 information obtained from INFO.ABFD or the previously selected
1039 architecture.
1040
1041 The ARCHES parameter is a linked list (sorted most recently used)
1042 of all the previously created architures for this architecture
1043 family. The (possibly NULL) ARCHES->gdbarch can used to access
1044 values from the previously selected architecture for this
1045 architecture family. The global \`\`current_gdbarch'' shall not be
1046 used.
104c1213
JM
1047
1048 The INIT function shall return any of: NULL - indicating that it
ec3d358c 1049 doesn't recognize the selected architecture; an existing \`\`struct
104c1213
JM
1050 gdbarch'' from the ARCHES list - indicating that the new
1051 architecture is just a synonym for an earlier architecture (see
1052 gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch''
4b9b3959
AC
1053 - that describes the selected architecture (see gdbarch_alloc()).
1054
1055 The DUMP_TDEP function shall print out all target specific values.
1056 Care should be taken to ensure that the function works in both the
1057 multi-arch and non- multi-arch cases. */
