1*7c3d14c8STreehugger RobotThis folder contains list of symbols that should be excluded from the builtin 2*7c3d14c8STreehugger Robotlibraries for Darwin. There are two reasons symbols are excluded: 3*7c3d14c8STreehugger Robot 4*7c3d14c8STreehugger Robot(1) They aren't supported on Darwin 5*7c3d14c8STreehugger Robot(2) They are contained within the OS on the minimum supported target 6*7c3d14c8STreehugger Robot 7*7c3d14c8STreehugger RobotThe builtin libraries must contain all symbols not provided by the lowest 8*7c3d14c8STreehugger Robotsupported target OS. Meaning if minimum deployment target is iOS 6, all builtins 9*7c3d14c8STreehugger Robotnot included in the ios6-<arch>.txt files need to be included. The one catch is 10*7c3d14c8STreehugger Robotthat this is per-architecture. Since iOS 6 doesn't support arm64, when supporting 11*7c3d14c8STreehugger RobotiOS 6, the minimum deployment target for arm64 binaries is iOS 7. 12
