These data areas are set up by Foundation to link in as real classes post facto. 15*8d741a5dSApple OSS Distributions * 16*8d741a5dSApple OSS Distributions * We keep these in a separate file so that we can include the runtime code in test subprojects but not include the data so that compiled code that sees the data in libSystem doesn't get confused by a second copy. Somehow these don't get unified in a common block. 17*8d741a5dSApple OSS Distributions **********************/ 18*8d741a5dSApple OSS Distributions 19*8d741a5dSApple OSS Distributions void * _NSConcreteStackBlock[32] = { 0 }; 20*8d741a5dSApple OSS Distributions void * _NSConcreteMallocBlock[32] = { 0 }; 21*8d741a5dSApple OSS Distributions void * _NSConcreteAutoBlock[32] = { 0 }; 22*8d741a5dSApple OSS Distributions void * _NSConcreteFinalizingBlock[32] = { 0 }; 23*8d741a5dSApple OSS Distributions void * _NSConcreteGlobalBlock[32] = { 0 }; 24*8d741a5dSApple OSS Distributions void * _NSConcreteWeakBlockVariable[32] = { 0 }; 25
