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
1038 components. Each component can independantly register their need
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
1048 GDB is built from a variable number of (fairly independant)
1049 components it was determined that the global aproach was not
1050 applicable. */
1051
1052
1053/* Register a new architectural family with GDB.
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
1066 The INIT function parameter INFO shall, as far as possible, be
1067 pre-initialized with information obtained from INFO.ABFD or
1068 previously selected architecture (if similar). INIT shall ensure
1069 that the INFO.BYTE_ORDER is non-zero.
1070
1071 The INIT function shall return any of: NULL - indicating that it
1072 doesn't reconize the selected architecture; an existing ``struct
1073 gdbarch'' from the ARCHES list - indicating that the new
1074 architecture is just a synonym for an earlier architecture (see
1075 gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
1076 - that describes the selected architecture (see
1077 gdbarch_alloc()). */
