597dcd8f3f [Stdlib][Frontend][CMake] Remove SWIFT_DARWIN_ENABLE_STABLE_ABI_BIT option, make it permanently on. 2019-03-13 09:31:50 -04:00

fbe990481b [Runtime] Dynamically select the is-Swift bit at runtime on Apple platforms. 
Recent Swift uses 2 as the is-Swift bit when running on newer versions, and 1 on older versions. Since it's difficult or impossible to know what we'll be running on at build time, make the selection at runtime.
