/* Mechanism for co-ordinating the selection of a specific
architecture.
GDB targets (*-tdep.c) can register an interest in a specific
architecture. Other GDB components can register a need to maintain
per-architecture data.
The mechanisms below ensures that there is only a loose connection
between the set-architecture command and the various GDB
components. Each component can independently register their need
1999-08-31 03:14:27 +02:00
to maintain architecture specific data with gdbarch.
Pragmatics:
Previously, a single TARGET_ARCHITECTURE_HOOK was provided. It
didn't scale.
The more traditional mega-struct containing architecture specific
data for all the various GDB components was also considered. Since
GDB is built from a variable number of (fairly independent)
1999-08-31 03:14:27 +02:00
components it was determined that the global aproach was not
applicable. */
/* Register a new architectural family with GDB.
Register support for the specified ARCHITECTURE with GDB. When
gdbarch determines that the specified architecture has been
selected, the corresponding INIT function is called.
--
The INIT function takes two parameters: INFO which contains the
information available to gdbarch about the (possibly new)
architecture; ARCHES which is a list of the previously created
\`\`struct gdbarch'' for this architecture.
The INFO parameter is, as far as possible, be pre-initialized with
information obtained from INFO.ABFD or the global defaults.
The ARCHES parameter is a linked list (sorted most recently used)
of all the previously created architures for this architecture
family. The (possibly NULL) ARCHES->gdbarch can used to access
values from the previously selected architecture for this
architecture family. The global \`\`current_gdbarch'' shall not be
used.
1999-08-31 03:14:27 +02:00
The INIT function shall return any of: NULL - indicating that it
doesn't recognize the selected architecture; an existing \`\`struct
1999-08-31 03:14:27 +02:00
gdbarch'' from the ARCHES list - indicating that the new
architecture is just a synonym for an earlier architecture (see
gdbarch_list_lookup_by_info()); a newly created \`\`struct gdbarch''
- that describes the selected architecture (see gdbarch_alloc()).
The DUMP_TDEP function shall print out all target specific values.
Care should be taken to ensure that the function works in both the
multi-arch and non- multi-arch cases. */
