/* Mechanism for co-ordinating the selection of a specific
|
| 938 |
|
|
architecture.
|
| 939 |
|
|
|
| 940 |
|
|
GDB targets (*-tdep.c) can register an interest in a specific
|
| 941 |
|
|
architecture. Other GDB components can register a need to maintain
|
| 942 |
|
|
per-architecture data.
|
| 943 |
|
|
|
| 944 |
|
|
The mechanisms below ensures that there is only a loose connection
|
| 945 |
|
|
between the set-architecture command and the various GDB
|
| 946 |
|
|
components. Each component can independently register their need
|
| 947 |
|
|
to maintain architecture specific data with gdbarch.
|
| 948 |
|
|
|
| 949 |
|
|
Pragmatics:
|
| 950 |
|
|
|
| 951 |
|
|
Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
|
| 952 |
|
|
didn't scale.
|
| 953 |
|
|
|
| 954 |
|
|
The more traditional mega-struct containing architecture specific
|
| 955 |
|
|
data for all the various GDB components was also considered. Since
|
| 956 |
|
|
GDB is built from a variable number of (fairly independent)
|
| 957 |
|
|
components it was determined that the global aproach was not
|
| 958 |
|
|
applicable. */

/* Register a new architectural family with GDB.
|
| 962 |
|
|
|
| 963 |
|
|
Register support for the specified ARCHITECTURE with GDB. When
|
| 964 |
|
|
gdbarch determines that the specified architecture has been
|
| 965 |
|
|
selected, the corresponding INIT function is called.

|
|
|
| 967 |
|
|
--
|
| 968 |
|
|
|
| 969 |
|
|
The INIT function takes two parameters: INFO which contains the
|
| 970 |
|
|
information available to gdbarch about the (possibly new)
|
| 971 |
|
|
architecture; ARCHES which is a list of the previously created
|
| 972 |
|
|
``struct gdbarch'' for this architecture.
|
| 973 |
|
|
|
| 974 |
|
|
The INFO parameter is, as far as possible, be pre-initialized with
|
| 975 |
|
|
information obtained from INFO.ABFD or the global defaults.
|
| 976 |
|
|
|
| 977 |
|
|
The ARCHES parameter is a linked list (sorted most recently used)
|
| 978 |
|
|
of all the previously created architures for this architecture
|
| 979 |
|
|
family. The (possibly NULL) ARCHES->gdbarch can used to access
|
| 980 |
|
|
values from the previously selected architecture for this
|
| 981 |
|
|
architecture family.
|
| 982 |
|
|
|
| 983 |
|
|
The INIT function shall return any of: NULL - indicating that it
|
| 984 |
|
|
doesn't recognize the selected architecture; an existing ``struct
|
| 985 |
|
|
gdbarch'' from the ARCHES list - indicating that the new
|
| 986 |
|
|
architecture is just a synonym for an earlier architecture (see
|
| 987 |
|
|
gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch''
|
| 988 |
|
|
- that describes the selected architecture (see gdbarch_alloc()).
|
| 989 |
|
|
|
| 990 |
|
|
The DUMP_TDEP function shall print out all target specific values.
|
| 991 |
|
|
Care should be taken to ensure that the function works in both the
|
| 992 |
|
|
multi-arch and non- multi-arch cases. */
