1032/* Mechanism for co-ordinating the selection of a specific
1033 architecture.
1034
1035 GDB targets (*-tdep.c) can register an interest in a specific
1036 architecture. Other GDB components can register a need to maintain
1037 per-architecture data.
1038
1039 The mechanisms below ensures that there is only a loose connection
1040 between the set-architecture command and the various GDB
0fa6923a 1041 components. Each component can independently register their need
104c1213
JM
1042 to maintain architecture specific data with gdbarch.
1043
1044 Pragmatics:
1045
1046 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
1047 didn't scale.
1048
1049 The more traditional mega-struct containing architecture specific
1050 data for all the various GDB components was also considered. Since
0fa6923a 1051 GDB is built from a variable number of (fairly independent)
104c1213
JM
1052 components it was determined that the global aproach was not
1053 applicable. */

1057
1058 Register support for the specified ARCHITECTURE with GDB. When
1059 gdbarch determines that the specified architecture has been
1060 selected, the corresponding INIT function is called.
1061
1062 --
1063
1064 The INIT function takes two parameters: INFO which contains the
1065 information available to gdbarch about the (possibly new)
1066 architecture; ARCHES which is a list of the previously created
1067 \`\`struct gdbarch'' for this architecture.

1069 The INFO parameter is, as far as possible, be pre-initialized with
1070 information obtained from INFO.ABFD or the previously selected
1071 architecture.
1072
1073 The ARCHES parameter is a linked list (sorted most recently used)
1074 of all the previously created architures for this architecture
1075 family. The (possibly NULL) ARCHES->gdbarch can used to access
1076 values from the previously selected architecture for this
1077 architecture family. The global \`\`current_gdbarch'' shall not be
1078 used.
104c1213
JM
1079
1080 The INIT function shall return any of: NULL - indicating that it
ec3d358c 1081 doesn't recognize the selected architecture; an existing \`\`struct
104c1213
JM
1082 gdbarch'' from the ARCHES list - indicating that the new
1083 architecture is just a synonym for an earlier architecture (see
1084 gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch''
