The GNUstep Objective-C runtime was designed as a drop-in replacement for
|
|
the GCC runtime. It supports three ABIs:
|
|
|
|
- The old GCC ABI, which provides support for Objective-C 1.0 features.
|
|
This can be selected via the -fobjc-runtime=gcc flag in Clang or by
|
|
compiling with GCC.
|
|
|
|
- The initial GNUstep non-fragile ABI, which was intended to be
|
|
compatible with the GCC ABI, but provide support for modern Objective-C
|
|
features. This can be selected with the -fobjc-runtime=gnustep-1.9 flag
|
|
in Clang.
|
|
|
|
- The modern (v2) ABI, which provides richer reflection metadata, smaller
|
|
binaries and reduced memory usage. This is selected with the
|
|
-fobjc-runtime=gnustep-2.0 flag in Clang 7.0 or later.
