1011/* Mechanism for co-ordinating the selection of a specific
1012 architecture.
1013
1014 GDB targets (*-tdep.c) can register an interest in a specific
1015 architecture. Other GDB components can register a need to maintain
1016 per-architecture data.
1017
1018 The mechanisms below ensures that there is only a loose connection
1019 between the set-architecture command and the various GDB
0fa6923a 1020 components. Each component can independently register their need
104c1213
JM
1021 to maintain architecture specific data with gdbarch.
1022
1023 Pragmatics:
1024
1025 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
1026 didn't scale.
1027
1028 The more traditional mega-struct containing architecture specific
1029 data for all the various GDB components was also considered. Since
0fa6923a 1030 GDB is built from a variable number of (fairly independent)
104c1213
JM
1031 components it was determined that the global aproach was not
1032 applicable. */

1036
1037 Register support for the specified ARCHITECTURE with GDB. When
1038 gdbarch determines that the specified architecture has been
1039 selected, the corresponding INIT function is called.
1040
1041 --
1042
1043 The INIT function takes two parameters: INFO which contains the
1044 information available to gdbarch about the (possibly new)
1045 architecture; ARCHES which is a list of the previously created
1046 \`\`struct gdbarch'' for this architecture.
1047
0f79675b
AC
1048 The INFO parameter is, as far as possible, be pre-initialized with
1049 information obtained from INFO.ABFD or the previously selected
1050 architecture.
1051
1052 The ARCHES parameter is a linked list (sorted most recently used)
1053 of all the previously created architures for this architecture
1054 family. The (possibly NULL) ARCHES->gdbarch can used to access
1055 values from the previously selected architecture for this
1056 architecture family. The global \`\`current_gdbarch'' shall not be
1057 used.
104c1213
JM
1058
1059 The INIT function shall return any of: NULL - indicating that it
ec3d358c 1060 doesn't recognize the selected architecture; an existing \`\`struct
104c1213
JM
1061 gdbarch'' from the ARCHES list - indicating that the new
1062 architecture is just a synonym for an earlier architecture (see
1063 gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch''
4b9b3959
AC
1064 - that describes the selected architecture (see gdbarch_alloc()).
1065
1066 The DUMP_TDEP function shall print out all target specific values.
1067 Care should be taken to ensure that the function works in both the
1068 multi-arch and non- multi-arch cases. */
