◆ anonymous enum

◆ FragileClassFlags

Enumerator
FragileABI_Class_Factory Apparently: is not a meta-class.
FragileABI_Class_Meta Is a meta-class.
FragileABI_Class_HasCXXStructors Has a non-trivial constructor or destructor.
FragileABI_Class_Hidden Has hidden visibility.
FragileABI_Class_CompiledByARC Class implementation was compiled under ARC.
FragileABI_Class_HasMRCWeakIvars Class implementation was compiled under MRC and has MRC weak ivars. Exclusive with CompiledByARC.

EmitImageInfo - Emit the image info marker used to encode some module level information.

See: rdr://4810609&4810587&4810587 struct IMAGE_INFO { unsigned version; unsigned flags; };

Enumerator
eImageInfo_FixAndContinue

◆ NonFragileClassFlags

Enumerator
NonFragileABI_Class_Meta Is a meta-class.
NonFragileABI_Class_Root Is a root class.
NonFragileABI_Class_HasCXXStructors Has a non-trivial constructor or destructor.
NonFragileABI_Class_Hidden Has hidden visibility.
NonFragileABI_Class_Exception Has the exception attribute.
NonFragileABI_Class_HasIvarReleaser (Obsolete) ARC-specific: this class has a .release_ivars method
NonFragileABI_Class_CompiledByARC Class implementation was compiled under ARC.
NonFragileABI_Class_HasCXXDestructorOnly Class has non-trivial destructors, but zero-initialization is okay.
NonFragileABI_Class_HasMRCWeakIvars Class implementation was compiled under MRC and has MRC weak ivars. Exclusive with CompiledByARC.
