Previously, specifying more than one simple template template parameter
resulted in a parse error. Now multiple template template parameters are
working including instantiation with %template. Example:
template <template<template<class> class, class> class Op, template<class> class X, class Y>
class C { ... };
Closes#624Closes#1021
Without this, perlhead.swg does `#pragma GCC diagnostic pop`
if `__GNUC__ >= 10` - without any prior `#pragma GCC diagnostic push`.
There's also a mismatch between the conditions that trigger
`#pragma GCC diagnostic ignored` (where the `push` should be)
and the attempt to `#pragma GCC diagnostic pop`.
ccache.c:738:18: runtime error: null pointer passed as argument 1, which is declared to never be null
Fixes stderr redirect in testname CCACHE_CPP2, when the CCACHE_CPP2
environment variable is defined.
mdfour.c:91:20: runtime error: left shift of 139 by 24 places cannot be represented in type 'int'
Looks like this brings some stability to the md4 hash calculation.

From Visual Studio 2022:
warning C4996: 'std::complex<int>::complex': warning STL4037: The effect of instantiating the template std::complex for any type other than float, double, or long double is unspecified. You can define _SILENCE_NONFLOATING_COMPLEX_DEPRECATION_WARNING to suppress this warning.
decltype now accepts C++ expressions instead of just an ID, such as:
int i,j;
... decltype(i+j) ...
... decltype(&i) ...
These result in a warning for non-trivial expressions which SWIG cannot evaluate:
Warning 344: Unable to deduce decltype for 'i+j'.
See 'Type Inference' in CPlusPlus.html for workarounds.

[PHP] Update docs for removal of -noproxy in SWIG 4.1.0

Problems handling < and > in template parameters are now fixed.
Remove illegal C++ code (template typedefs) - replace with a function
using same template.
Recent commits ensure types are correctly stored in SwigType *. In
particular template parameters are enclosed within '<(' and ')>'.
Now we can confidently handle template parameters as really being
delimited as such to fix an infinite loop handling template expressions
containing '<' or '>'. The previous implementation only assumed
template parameters were delimited by '<' and '>'.
Issue #1037
Further corrections to pass SwigType * to methods expecting types
instead of passing readable type strings.
Swig_string_mangle() takes a generic String *, but it was calling
functions that require SwigType *. Swig_string_mangle_type() is
now provided for SwigType *.
The previous commit is a pre-requisite in order to prevent duplicate
symbols from being generated in the C++ wrappers.
Named duplicate class template instantiations now issue a warning and are ignored.
Duplicate empty class template instantiations are quietly ignored.
The test cases are fixed for this new behaviour.
This commit is a pre-requisite for the near future so that the Python
builtin wrappers can correctly use the SwigType_namestr function without
generating duplicate symbol names.
Further corrections to pass SwigType * to methods expecting types
instead of passing readable type strings.
Swig_string_mangle() takes a generic String *, but it was calling
functions that require SwigType *. Swig_string_mangle_type() is
now provided for SwigType *r. The special template handling
on types now occurs in this function.
Further corrections to pass SwigType * to methods expecting types
instead of passing readable type strings.
Required reworking code that adds a fake inheritance for smart pointers
using the smartptr feature. Swig_smartptr_upcast() added as a support
function for this.
Fixes infinite loop due to () brackets in a non-type template
parameter containing an expression
Fixes#2418
Non-trivial expressions are still not qualified properly though.
Further switch to use rtypecheck typemaps instead of hard coded logic.
The full switch to typemaps is deferred until swig-4.2 as it can't be fully
backwards compatible. For now a warning is provided to help the
transition. It provides the full typemap that should be placed into
a user's interface file, for example:
%typemap("rtype") int32_t * "integer"
void testmethod(int32_t * i);
void testmethod();
If there is no rtypecheck typemap for int32_t *, the warning shown is:
example.i:7: Warning 750: Optional rtypecheck code is deprecated. Add the
following typemap to fix as the next version of SWIG will not work without it:
%typemap("rtypecheck") int32_t * %{ (is.integer($arg) || is.numeric($arg)) %}
The warning is shown for any code that previously used "numeric", "integer" or
"character" for the rtype typemap. Copying the rtypecheck typemap as
shown into the user interface file will provide the appropriate fix and
the warning will disappear. This is important to do as swig-4.2 will
not be able to provide this helpful warning.
- Fix for special variable $argtype expansion in rtypecheck typemap.
- Remove unnecessary () brackets when using rtypecheck typemap for
single parameter functions.
- Add rtypecheck typemaps for shared_ptr so that NULL can be used
in overloaded functions taking shared_ptr.
when incorrect types passed are passed to the overloaded methods.
Old unhelpful error message:
Error in f(...) : could not find function "f"
Example of new improved error message:
Error in use_count(k) :
cannot find overloaded function for use_count with argtypes (NULL)
