- Guarded devirtualization pass of virtual method calls reduces their run-time cost and enables
the compiler to inline their targets.
- Provided exact type information, this optimization can convert a virtual call into a more
efficient direct call. When no type information is available, the most probable target of
the virtual method can be predicted, and the optimization devirtualizes the call by guarding
it with a cheap run-time class test to verify that the predicted method is in fact the target.
