  • iOS/IL2CPP: Correctly invoke an action pointing to an extension method.
  • iOS/IL2CPP: Correctly lazy initialize the type information when Type.GetDeclaringType is called.
  • iOS/IL2CPP: Emit memory barriers to ensure the correct acquire and release semantics are enforced for loads and stores of volatile fields.
  • iOS/IL2CPP: Ensure that background threads which are not explicitly joined have their resources freed so that the runtime does not leak thread handles.
