What do you mean by that?

IR verification fails because post-parse call devirtualization was not able to replace the `invokeBasic` by an `invokeStatic` in the C2 compiled `testMethodHandleCallWithCCP` method. In theory, that should not be dependent on the availability of C1. So I'm wondering why it fails without C1. Did you check if increasing the number of warmup iterations helps?
