This will also avoid some interpreter transitions on wasm, making the stack traces on BCL test suite crashes etc. smaller. |

what would be the additional cases that would fit into the fastpath approach?

I am trying to understand the code and the effect that covering more cases would bring.

We don't have some helper function that does this already?

The calls are of the form: .constrained T_GSHAREDVT callvirt <method> Whenever T_GSHAREDVT is a reference or value type is only known at runtime. Previously these were handled by passing the arguments to a JIT icall which computed the target method and did a runtime invoke. Added 2 optimizations: * Precompute the data which depends only on the type and the method, store it in an rgctx slot and pass it to the JIT icall. * Add a fastpath for simpler cases which makes an indirect call from generated code.
