URL: https://github.com/llvm/llvm-project/commit/19ab2664ad3182ffa8fe3a95bb19765e4ae84653 DIFF: https://github.com/llvm/llvm-project/commit/19ab2664ad3182ffa8fe3a95bb19765e4ae84653.diff LOG: [NFC] [C++20] [Coroutines] Mention the side effect of a fix may bring regressions The fix we sent for https://github.com/llvm/llvm-project/issues/56301 may bring performance regressions. But we didn't mention it in the ReleaseNotes so that users may get confused. e.g, https://github.com/llvm/llvm-project/issues/64933. So this patch mentions the possible side effect and the potential solutions in https://github.com/llvm/llvm-project/issues/64945 to avoid misunderstandings.
