Update devel/gnustep-objc to 2.1.0 and fix its build
Highlights of 2.1.0 release include:
- Numerous improvements to the Objective-C++ exception interoperation code.
The runtime now dynamically detects whether the libcxxrt or libsupc++ variant
of the Itanium C++ Exception ABI is being used
- Sending a message to `super` where the corresponding method did not exist was
silently ignored in previous versions of the runtime. This now correctly
invokes the forwarding hooks and so (with an implementation of the Foundation
framework, such as GNUstep Base or WinObjC) will trigger an exception or
invoke `forwardInvocation:`.
- The checks for overloaded memory management methods were incorrect, causing
some classes to be incorrectly opted into ARC fast paths. These checks are
now correct.
- Several memory management bugs in corner cases of weak reference management
were fixed.
- The ARM assembly implementation of `objc_msgSend` now correctly restores the
stack after calling a forwarding implementation. This bug caused stack
corruption and usually crashing on ARM.
- The ARC code has been rewritten as C++, using a well-tested third-party
Robin-Hood hash table to store weak references, replacing the home-grown
version. This improves performance and reduces the likelihood of bugs
arising from the hash table implementation.
- Control Flow Guard (CGF) checks were added on Windows on x86 (32- and
64-bit). If Objective-C code is compiled with CFG enabled then
`objc_msgSend` will crash if it attempts to jump to an address that is not a
valid function entry point.
- The function signatures in the blocks headers were updated for compatibility
with recent macOS releases.
- Support for the C11 _Atomic type qualifier in property metadata was added.
Highlights of 2.0.0 release include:
- The linker now removes duplicate selectors within a library.
- The linker will remove duplicate protocol definitions within a library.
- Protocols and classes are now always accessed via an indirection layer, so
they can be extended by future versions of the ABI without breaking
compatibility.
- Categories can include property metadata and both categories.
- Constant strings are now emitted with a richer structure, which provides
faster hashing and better unicode support.
- Instance variable metadata includes size and alignment, allowing better object
layout and more accurate introspection. Instance variable metadata now
includes more accurate information about ARC ownership semantics.
- Method metadata now includes extended type information, allowing bridged
languages to understand the class that methods expect and not just the fact
that they take an object. This was previously an obstacle to supporting
JavaScriptCore's Objective-C bridge with GNUstep.
In addition to the new ABI, there are several improvements on Windows:
- The runtime now uses SEH-based exception handling on Windows. This
interoperates with C++ exceptions in libraries compiled with MSVC or
MSVC-compatible compilers.
- All of the assembly code paths now fully support i386 and x64 Windows.
- Object allocations on 32-bit Windows now use `_aligned_malloc` to guarantee
sufficient alignment for AVX vectors in instance variables.
- The runtime now uses fibre-local storage and critical sections on Windows,
improving performance in multithreaded workloads on Windows.
- Public runtime functions are now marked dllexport, so the runtime can be built
as objc.dll on Windows.
**WARNING**: The new ABI is currently incompatible with incremental linking on
Windows, so projects built with Microsoft's linker must disable incremental
linking.
Note: Microsoft's WinObjC project contains a friendly fork of this library that
includes a work around for the incremental linking issue. If you wish to use
incremental linking on Windows, please use that version. A subsequent version
of clang and link.exe should include a fix that will make it possible to use
this version with incremental linking.
The runtime will now use the new ABI's data structures internally and will
automatically upgrade on-disk structures from old ABIs when used with the old
ABI. As a result, memory usage will be higher when using the old ABI and users
who are unable to recompile their code may prefer to stick with the 1.9.x
release series. Mixing libraries compiled with the old and new ABIs is not
supported and will abort at run time.
The new ABI provides better run-time introspection metadata and smaller
binaries. When used with the new ABI, this version of the runtime will consume
less memory than the previous release.
Highlights of 1.9.0 release include:
- Support for 64-bit ARM (AArch64) processors, including assembly fast paths
for message sending.
- Improved the dispatch table representation to improve performance and cache
usage on the fast path.
- The implementation of `imp_implementationWithBlock`, the function that allows
blocks to be used as methods, no longer requires physical pages to be mapped
both writeable and executable.
- Numerous improvements to the interaction between runtime functions and ARC.
- Support for Thumb-2 interworking on ARM. Note that the library must be
compiled for ARMv7 or ARMv6T2 for this code to be enabled. Once it has been,
other Objective-C binaries linked with the library can be compiled as ARM or
Thumb-2 code. This will also generate Thumb-2 message send functions,
improving instruction cache usage.
- Significant improvements to ARC, including
* The runtime no longer acquires a global lock on every object deallocation (a
global lock is still used for objects that have weak references). *NOTE:*
This is incompatible with other code directly inspecting the reference
count and will break with older versions of GNUstep Base!
* Weak references use a scheme closer to C++ `std::weak_pointer` and are
lazily zeroed on access. This reduces the space overheads for weak
references.
* Some additional helper functions are added for use in `NSObject` and other
root classes, which simplifies the layering between the runtime and the
Foundation (or equivalent) implementation.
- Improvements to how the runtime handles layout of ivars with strong alignment
requirements, which should fix issues relating to using vector types in
Objective-C objects.
- The option to build a separate libobjcxx has been removed. The runtime will
now depend on the C++ standard library implementation if no useable C++
runtime is available. Note that C++ exception interworking does not work
because LLVM's libc++abi (shipped by Apple) does not provide GNU-compatible
hooks and so Objective-C++ exception support will be automatically disabled
on this platform. Any other platforms shipping libc++abi should consider
either GNU libsupc++ or libcxxrt as an alternative

Update gnustep-objc to 1.8.1 This is required to fix the build of gnustep-make on NetBSD 9.0 Changes since previous version in pkgsrc: Version 1.8 - Added API for tracing, allowing interposition on all message sends matching a given selector. - Numerous bug fixes and stability improvements. Version 1.7 - A new CMake-based build system. This makes all of the configurable options available via a clean interface. CPack is supported for building RPM and DEB packages out of the box. - A new CTest-based test suite, replacing the old ad-hoc tests. - Build a single libobjc with support for Objective-C++ on platforms where a C++ ABI library (libcxxrt or libsupc++) is installed as a shared library. - Added specialised property accessor functions and support for atomic properties with C++ non-POD types. - Significant improvements in property introspection and an exhaustive test suite. - Improved integration with libdispatch. The runtime will correctly register work queues with the garbage collector or create autorelease pools around block invocations. - A new exception implementation providing better integration with foreign exceptions (e.g. C++ exceptions). The new ABI is supported by clang 3.3 when compiling with -fobjc-runtime=gnustep-1.7 (or higher). The old ABI is still supported and both can be used within the same program, however code compiled with the old ABI remains unreliable in the presence of foreign exceptions. It is strongly recommended that anyone using exceptions with Objective-C++ switches to the new version. - MIPS64 support in the assembly routines. Currently these are only tested with the n64 ABI. They are believed to work with n32 and o32, but should be considered unsupported on these platforms. - Small algorithmic improvement to the objc_msgSend() implementation, giving approximately a 10% speedup (architecture-dependent) on message sends. - Updated optimisation passes to work with LLVM 3.2 and recent LLVM trunk.

Update gnustep-objc to 1.6.1. Changes are too numerous to list here, but essentially this switches gnustep-objc to libobjc2-1.6.1 in order to provide a modern runtime and support modern Objective-C 2.0 features such as ARC, class extensions, the nonfragile ABI, etc.
