SILOptimizer: Replace Array.append(contentsOf: with Array.append(elem… #5978
It looks like generated SIL for array operations is different on Linux. This is probably due to the lack of bridging on Linux. Can you try to formulate the test-case in a platform independent way? If it is not possible, you could try to write two different tests and specify that one of them should run on platforms with objc-interop and the other on platforms without objc-interop?
