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