/* 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
|
|
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)
|
|
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 INIT function parameter INFO shall, as far as possible, be
|
|
pre-initialized with information obtained from INFO.ABFD or
|
|
previously selected architecture (if similar). INIT shall ensure
|
|
that the INFO.BYTE_ORDER is non-zero.
|
|
|
|
The INIT function shall return any of: NULL - indicating that it
|
|
doesn't recognize the selected architecture; an existing \`\`struct
|
|
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. */
