+
+// This package recognizes the conditional compilation flags listed below.
+// To use enable them, uncomment the corresponding lines or define them
+// from the package manager command line:
+//
+//     swift build -Xswiftc -DCOLLECTIONS_INTERNAL_CHECKS
+var settings: [SwiftSetting] = [
+
+  // Enables internal consistency checks at the end of initializers and
+  // mutating operations. This can have very significant overhead, so enabling
+  // this setting invalidates all documented performance guarantees.
+  //
+  // This is mostly useful while debugging an issue with the implementation of
+  // the hash table itself. This setting should never be enabled in production
+  // code.
+//  .define("COLLECTIONS_INTERNAL_CHECKS"),
+
+  // Hashing collections provided by this package usually seed their hash
+  // function with the address of the memory location of their storage,
+  // to prevent some common hash table merge/copy operations from regressing to
+  // quadratic behavior. This setting turns off this mechanism, seeding
+  // the hash function with the table's size instead.
+  //
+  // When used in conjunction with the SWIFT_DETERMINISTIC_HASHING environment
+  // variable, this enables reproducible hashing behavior.
+  //
+  // This is mostly useful while debugging an issue with the implementation of
+  // the hash table itself. This setting should never be enabled in production
+  // code.
+//  .define("COLLECTIONS_DETERMINISTIC_HASHING"),
