/* As of 2004-01-17 only the 32-bit SPARC ABI has been identified as an
|
|
ABI suitable for the implementation of a robust extract
|
|
struct-convention return-value address method (the sparc saves the
|
|
address in the callers frame). All the other cases so far examined,
|
|
the DEPRECATED_EXTRACT_STRUCT_VALUE implementation has been
|
|
erreneous - the code was incorrectly assuming that the return-value
|
|
address, stored in a register, was preserved across the entire
|
|
function call.
|
|
For the moment retain DEPRECATED_EXTRACT_STRUCT_VALUE as a marker of
|
|
the ABIs that are still to be analyzed - perhaps this should simply
|
|
be deleted. The commented out extract_returned_value_address method
|
|
is provided as a starting point for the 32-bit SPARC. It, or
|
|
something like it, along with changes to both infcmd.c and stack.c
|
|
will be needed for that case to work. NB: It is passed the callers
|
|
frame since it is only after the callee has returned that this
|
|
function is used.

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 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.
|
|
|
|
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. */
