Fixes: https://bugs.swift.org/browse/SR-3455 https://bugs.swift.org/browse/SR-3663 https://bugs.swift.org/browse/SR-4032 https://bugs.swift.org/browse/SR-4031 Now, compilation conditions are validated at first, then evaluated. Also, in non-Swift3 mode, '&&' now has higher precedence than '||'. 'A || B && C || D' are evaluated as 'A || (B && C) || D'. Swift3 source breaking changes: * [SR-3663] This used to be accepted and evaluate to 'true' because of short circuit without any validation. #if true || true * 12 = try Anything is OK? print("foo") #endif In this change, remaining expressions are properly validated and diagnosed if it's invalid. * [SR-4031] Compound name references are now diagnosed as errors. e.g. `#if os(foo:bar:)(macOS)` or `#if FLAG(x:y:)` Swift3 compatibility: * [SR-3663] The precedence of '||' and '&&' are still the same and the following code evaluates to 'true'. #if false || true && false print("foo") #endif
