1This folder contains list of symbols that should be excluded from the builtin2libraries for Darwin. There are two reasons symbols are excluded:3 4(1) They aren't supported on Darwin5(2) They are contained within the OS on the minimum supported target6 7The builtin libraries must contain all symbols not provided by the lowest8supported target OS. Meaning if minimum deployment target is iOS 6, all builtins9not included in the ios6-<arch>.txt files need to be included. The one catch is10that this is per-architecture. Since iOS 6 doesn't support arm64, when supporting11iOS 6, the minimum deployment target for arm64 binaries is iOS 7.12
