You can probably get the mangled name of the metatype, and refer to that. Eg,
public func f() -> Any.Type {
return Int.self
}
f()
Compile this with -emit-ir:
@_TMSi = external global %swift.type, align 8
define %swift.type* @_TF4blah1fFT_PMP_() #0 {
entry:
ret %swift.type* @_TMSi
}
So in your C++ program,
extern "C" {
extern void *_TMSi;
}
Note that this is completely unsupported, and probably insane. You have been
warned.
