This OS has been unsupported for over 20 years. We stopped providing
macswig builds more than 20 years ago too:

The required SIOUX library doesn't seem to be available anywhere
now either.
Closes#2323
Avoid using reserved identifiers such as `_DOHINT_H` (fixes#1989),
fix cases where the name doesn't match the filename, and make the naming
more consistent and less likely to collide with include guards in other
headers.
Changes based on supplied patch, but reworked version not tested as
I don't have access to AIX and the submitter hasn't responded in
18 months.
Fixes#1920
Change these typemaps to assume that after a function call,
the parameter has been moved. The parameter's proxy class
that owns the C++ object thus has the underlying pointer set
to null so the object cannot be used again and the object is deleted.
Scrap new javarelease typemap and move contents into javabody typemap.
This works by transferring ownership of the underlying C++ memory
from the target language proxy class to an instance of the unique_ptr
which is passed to the wrapped function via std::move.
The proxy class has a new swigRelease() method which sets the
underlying C++ pointer for the proxy class to null, so working
in much the same way as std::unique_ptr::release(). Any attempt at
using the proxy class will be the same as if the delete() function
has been called on the proxy class. That is, using a C++ null pointer,
when a non-null pointer is usually expected.
This commit relies on the previous commit that uses std::move
on the temporary variable used for the wrapped function's input parameter
as std::unique_ptr is not copyable, it has move-only semantics.
Under %feature("php:type", "compat") we don't generate return type
declaration for virtual methods if directors are enabled for that class.
However if a base class of the class has a method of the same name which
isn't directed this was still getting a return type declaration which
caused PHP to give an error when it tried to load the module.
Now we detect this situation and suppress the base class method's
return type declaration too.
Re-enable testcase director_redefined which now works again (it was
failing under PHP8 due to this issue).

This was created by fc6269a3ca which
converted the non-functioning Octave 6.4 into a duplicate of the
other Octave build instead of dropping it completely.
Performance optimisation for parameters passed by value that are C++11 movable.
Test copy constructor and assignment operator calls for movable types

Changing the hash function breaks some testcases.
It seems there's a latent bug here (I suspect something somewhere in
SWIG depends on the hash iteration order), but I didn't see where and
we can't really have CI continuing to fail.
See #2303.
This reverts commit 5a96a39aa4.
Encapsulate the code to generate arginfo in the PHPTypes class.
By itself this should result in no functional changes, but it's
a step towards being able to delay arginfo generation which I
think is necessary to address the incompatible overridden
method problem discussed in #2151.
The C++ wrappers create a temporary variable for a parameter to be passed to a
function. This is initially default constructed and then copy assigned from the
instance being passed in from the target language. This is unchanged, however,
when the temporary variable is passed to wrapped function, it is now done using
std::move. If the type is move constructible, the move constructor will be used
instead of the copy constructor.
Note that the implementation calls std::move for all user-defined types
(non-primitive types passed by value), this excludes anything passed by pointer,
reference and arrays. It does also include any type that has not been
defined/parsed by SWIG, that is, unknown types. std::move is called via the
SWIG_STD_MOVE macro which only calls std::move for C++11 and later code.
This is the current state of play where the copy constructor and copy
assignment operators are called, even for movable types passed as
function parameters.
The XML target language support is not in good shape and is likely to be
removed unless somebody steps up to bring it up to the expected standard
(it fails to even meet the criteria for "Experimental" currently).
Closes#2213
The one we're currently using only considers the last five characters
plus the least significant bit of the last-but-sixth character, which
unsurprisingly generates a lot of many-way collisions.
This change seems to give about a 4% reduction in wallclock time for
processing li_std_list_wrap.i from the testsuite for Python. The
hash collision rate for this example drops from 39% to 0!
Closes#2303
The directorin typemaps in the director methods now use std::move on the
input parameter when copying the object from the stack to the heap prior
to the callback into the target language, thereby taking advantage of
move semantics if available.
