@ChuanqiXu9, I actually did the FE changes first and most of the FE logic are in `Sema` now. One question: there does not seem to be an obvious way to get the `llvm::CallBase` from `CodeGenFunction::EmitCallExpr`. I can only get the `llvm::Value *` for the return value then call `llvm::Value::users()` to find the call. Is there a better way to do this?

P.S. Name of the attribute is changed to `[[clang::coro_inplace_task]]`. I will try to do the Middle End changes as you suggested tomorrow and hopefully get rid of the `llvm.coro.safe.elide` intrinsic.
