Hi Everyone, I've just branched the 1.0 release of libobjc2. A great many thanks to everyone who tested this, who sent me bug reports and test cases, and most especially to the people who fixed bugs for me.
This runtime supports both the legacy GCC-compatible ABI and a new ABI that is fully supported by clang 2.8 and hopefully, thanks to Nicola's work, in future versions of GCC. It also supports a few features not found anywhere else, such as type-dependent dispatch, which means that programs that will corrupt the stack with other runtimes can be handled safely. The slot mechanism allows Self-style inline caching, eliminating the cost of message lookup in common cases and allowing speculative inlining to be performed safely. In the opts/ directory, there are several LLVM optimisation passes that make use of this. Thanks again to everyone who helped make this release possible, with testing, suggestions, and advice, David GNUstep Objective-C Runtime 1.0 =============================== This is the first official release of the GNUstep Objective-C runtime (a.k.a. libobjc2). This runtime was designed to support the features of Objective-C 2 for use with GNUstep and other Objective-C programs. You may obtain the code for this release from subversion at the following subversion branch: svn://svn.gna.org/svn/gnustep/libs/libobjc2/1.0 Alternatively, a tarball is available from: http://download.gna.org/gnustep/libobjc2-1.0.tar.bz2 The runtime library is responsible for implementing the core features of the object model, as well as exposing introspection features to the user. The GNUstep runtime implements Apple's Objective-C Runtime APIs, and a small number of GCC APIs for legacy compatibility. This library is based on the Étoilé Objective-C Runtime, an earlier research prototype, and includes support for non-fragile instance variables, type-dependent dispatch, and object planes. It is fully compatible with the FSF's GCC Objective-C ABI and also implements a new ABI that is supported by Clang and is required for some of the newer features. Although the runtime has been tested by several people, and is being used extensively by the Étoilé project, it is entirely new (MIT licensed) code and may still contain bugs. If you come across any problems, please report them to the GNUstep Developer mailing list <[email protected]>. A 1.1 release, fixing any bugs that are encountered in wider deployment, is planned to coincide with the next GNUstep release. _______________________________________________ Discuss-gnustep mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnustep
