995 architecture.
996
997 GDB targets (*-tdep.c) can register an interest in a specific
998 architecture. Other GDB components can register a need to maintain
999 per-architecture data.
1000
1001 The mechanisms below ensures that there is only a loose connection
1002 between the set-architecture command and the various GDB
0fa6923a 1003 components. Each component can independently register their need
104c1213
JM
1004 to maintain architecture specific data with gdbarch.
1005
1006 Pragmatics:
1007
1008 Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
1009 didn't scale.
1010
1011 The more traditional mega-struct containing architecture specific
1012 data for all the various GDB components was also considered. Since
0fa6923a 1013 GDB is built from a variable number of (fairly independent)
104c1213
JM
1014 components it was determined that the global aproach was not
1015 applicable. */

1019
1020 Register support for the specified ARCHITECTURE with GDB. When
1021 gdbarch determines that the specified architecture has been
1022 selected, the corresponding INIT function is called.
1023
1024 --
1025
1026 The INIT function takes two parameters: INFO which contains the
1027 information available to gdbarch about the (possibly new)
1028 architecture; ARCHES which is a list of the previously created
1029 \`\`struct gdbarch'' for this architecture.
1030
0f79675b
AC
1031 The INFO parameter is, as far as possible, be pre-initialized with
1032 information obtained from INFO.ABFD or the previously selected
1033 architecture.
1034
1035 The ARCHES parameter is a linked list (sorted most recently used)
1036 of all the previously created architures for this architecture
1037 family. The (possibly NULL) ARCHES->gdbarch can used to access
1038 values from the previously selected architecture for this
1039 architecture family. The global \`\`current_gdbarch'' shall not be
1040 used.
104c1213
JM
1041
1042 The INIT function shall return any of: NULL - indicating that it
ec3d358c 1043 doesn't recognize the selected architecture; an existing \`\`struct
104c1213
JM
1044 gdbarch'' from the ARCHES list - indicating that the new
1045 architecture is just a synonym for an earlier architecture (see
1046 gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch''
4b9b3959
AC
1047 - that describes the selected architecture (see gdbarch_alloc()).
1048
1049 The DUMP_TDEP function shall print out all target specific values.

1051 multi-arch and non- multi-arch cases. */
