1020/* Mechanism for co-ordinating the selection of a specific
1021 architecture.
1022
1023 GDB targets (*-tdep.c) can register an interest in a specific
1024 architecture. Other GDB components can register a need to maintain
1025 per-architecture data.
1026
1027 The mechanisms below ensures that there is only a loose connection
1028 between the set-architecture command and the various GDB
0fa6923a 1029 components. Each component can independently register their need
104c1213
JM
1030 to maintain architecture specific data with gdbarch.
1031
1032 Pragmatics:
1033
1034 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
1035 didn't scale.
1036
1037 The more traditional mega-struct containing architecture specific
1038 data for all the various GDB components was also considered. Since
0fa6923a 1039 GDB is built from a variable number of (fairly independent)
104c1213
JM
1040 components it was determined that the global aproach was not
1041 applicable. */

1045
1046 Register support for the specified ARCHITECTURE with GDB. When
1047 gdbarch determines that the specified architecture has been
1048 selected, the corresponding INIT function is called.
1049
1050 --
1051
1052 The INIT function takes two parameters: INFO which contains the
1053 information available to gdbarch about the (possibly new)
1054 architecture; ARCHES which is a list of the previously created
1055 \`\`struct gdbarch'' for this architecture.
1056
0f79675b
AC
1057 The INFO parameter is, as far as possible, be pre-initialized with
1058 information obtained from INFO.ABFD or the previously selected
1059 architecture.
1060
1061 The ARCHES parameter is a linked list (sorted most recently used)
1062 of all the previously created architures for this architecture
1063 family. The (possibly NULL) ARCHES->gdbarch can used to access
1064 values from the previously selected architecture for this
1065 architecture family. The global \`\`current_gdbarch'' shall not be
1066 used.
104c1213
JM
1067
1068 The INIT function shall return any of: NULL - indicating that it
ec3d358c 1069 doesn't recognize the selected architecture; an existing \`\`struct
104c1213
JM
1070 gdbarch'' from the ARCHES list - indicating that the new
1071 architecture is just a synonym for an earlier architecture (see
1072 gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch''
4b9b3959
AC
1073 - that describes the selected architecture (see gdbarch_alloc()).
1074
1075 The DUMP_TDEP function shall print out all target specific values.
1076 Care should be taken to ensure that the function works in both the
1077 multi-arch and non- multi-arch cases. */
