1This folder contains list of symbols that should be excluded from the builtin 2libraries for Darwin. There are two reasons symbols are excluded: 3 4(1) They aren't supported on Darwin 5(2) They are contained within the OS on the minimum supported target 6 7The builtin libraries must contain all symbols not provided by the lowest 8supported target OS. Meaning if minimum deployment target is iOS 6, all builtins 9not included in the ios6-<arch>.txt files need to be included. The one catch is 10that this is per-architecture. Since iOS 6 doesn't support arm64, when supporting 11iOS 6, the minimum deployment target for arm64 binaries is iOS 7. 12
