RuntimeInformation(https://github.com/lambdageek/mono/blob/mjit/mcs/class/Mono.Compiler/Mono.Compiler/RuntimeInformation.cs#L55) such as
ComputeStaticFieldAddressthat call into the runtime to get the required info. A more involved example (that we didn't get to during hack week) might be for a call from one method to another - in that case we would need to provide an internal call method where we could query the runtime for the address of the callee if it has already been JITed, or else cooperate on setting up a trampoline to JIT the callee the first time it is needed.
