Looking at the code, I think the optimization here is that, the LambdaForm will just have a single call site for all the cases, whereas the intrinsic does emit a call per case? i.e. the point is that these do not necessarily have to do exactly the same thing? I remember that having a call site per case was important from implementing this, since even if the selector is not a constant, we can then still inline each individual call site. Whereas with a single shared call site, the method handle would become not constant. ------------- PR Comment: https://git.openjdk.org/jdk/pull/23763#issuecomment-2697769525
