Avoiding VWT copies when passing raw memory to unspecialized generic parameters

Hi everyone, I've been working on a low-level dispatch bridge where I receive an UnsafeRawPointer and a metatype (Any.Type), and need to forward the underlying value to an unspecialized generic function: func foo<T>(_ value: T) { print(T.self, type(of: value)) } An argument to an unspecialized generic function foo<T>(_ value: T) is passed indirectly as @in_guaranteed T (a pointer in x0 and type metadata in x1). Since the value is already initialized in memory at the raw pointer location, m...
