GNUstep Objective-C Runtime 1.x
|
|
===============================
|
|
|
|
This the ninth official release of the GNUstep Objective-C runtime (a.k.a.
|
|
libobjc2). This runtime was designed to support the features of modern
|
|
dialects of Objective-C for use with GNUstep and other Objective-C programs.
|
|
Highlights of this release include:
|
|
|
|
- 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.
|
|
|
|
You may obtain the code for this release from git and use the 1.x branch:

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 backwards compatible
|
|
with the FSF's GCC 4.2.1 Objective-C ABI and also implements a new ABI that is
|
|
supported by Clang and Étoilé's LanguageKit and is required for some of the
|
|
newer features.
