Are indirect calls tested? I see clang/test/CodeGen/ptrauth-function-lvalue-cast.c testing indirect call via `char *ptr` casted to desired function type, but I don't see a test when we just have a signed function pointer (for example, passed by an argument to a function) and call the function that way. Please let me know if I miss smth.
