// Helper functions for running the type-names.rs test under CDB

// CDB exposes an "object model" via JavaScript that allows you to inspect debugging info - in this
// case we want to ask the object model for the return and parameter types for a local variable
// that is a function pointer to make sure that we are emitting the function pointer type in such a
// way that CDB understands how to parse it.
