1029/* Mechanism for co-ordinating the selection of a specific
1030 architecture.
1031
1032 GDB targets (*-tdep.c) can register an interest in a specific
1033 architecture. Other GDB components can register a need to maintain
1034 per-architecture data.
1035
1036 The mechanisms below ensures that there is only a loose connection
1037 between the set-architecture command and the various GDB
0fa6923a 1038 components. Each component can independently register their need
104c1213
JM
1039 to maintain architecture specific data with gdbarch.
1040
1041 Pragmatics:
1042
1043 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
1044 didn't scale.
1045
1046 The more traditional mega-struct containing architecture specific
1047 data for all the various GDB components was also considered. Since
0fa6923a 1048 GDB is built from a variable number of (fairly independent)
104c1213
JM
1049 components it was determined that the global aproach was not
1050 applicable. */

1054
1055 Register support for the specified ARCHITECTURE with GDB. When
1056 gdbarch determines that the specified architecture has been
1057 selected, the corresponding INIT function is called.
1058
1059 --
1060
1061 The INIT function takes two parameters: INFO which contains the
1062 information available to gdbarch about the (possibly new)
1063 architecture; ARCHES which is a list of the previously created
1064 \`\`struct gdbarch'' for this architecture.
1065
0f79675b
AC
1066 The INFO parameter is, as far as possible, be pre-initialized with
1067 information obtained from INFO.ABFD or the previously selected
1068 architecture.
1069
1070 The ARCHES parameter is a linked list (sorted most recently used)
1071 of all the previously created architures for this architecture
1072 family. The (possibly NULL) ARCHES->gdbarch can used to access
1073 values from the previously selected architecture for this
1074 architecture family. The global \`\`current_gdbarch'' shall not be
1075 used.
104c1213
JM
1076
1077 The INIT function shall return any of: NULL - indicating that it
ec3d358c 1078 doesn't recognize the selected architecture; an existing \`\`struct
104c1213
JM
1079 gdbarch'' from the ARCHES list - indicating that the new
1080 architecture is just a synonym for an earlier architecture (see
1081 gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch''
4b9b3959
AC
1082 - that describes the selected architecture (see gdbarch_alloc()).
1083
1084 The DUMP_TDEP function shall print out all target specific values.
1085 Care should be taken to ensure that the function works in both the
1086 multi-arch and non- multi-arch cases. */
