示例1: SILDeclRef
static std::pair<ManagedValue, SILDeclRef>
getNextUncurryLevelRef(SILGenFunction &SGF, SILLocation loc, SILDeclRef thunk,
ManagedValue selfArg, SubstitutionMap curriedSubs) {
auto *vd = thunk.getDecl();
// Reference the next uncurrying level of the function.
SILDeclRef next = SILDeclRef(vd, thunk.kind);
assert(!next.isCurried);
auto constantInfo = SGF.SGM.Types.getConstantInfo(next);
// If the function is natively foreign, reference its foreign entry point.
if (requiresForeignToNativeThunk(vd))
return {ManagedValue::forUnmanaged(SGF.emitGlobalFunctionRef(loc, next)),
next};
// If the thunk is a curry thunk for a direct method reference, we are
// doing a direct dispatch (eg, a fragile 'super.foo()' call).
if (thunk.isDirectReference)

next};
if (auto *func = dyn_cast<AbstractFunctionDecl>(vd)) {

// Use the dynamic thunk if dynamic.
if (vd->isObjCDynamic()) {
return {SGF.emitDynamicMethodRef(loc, next, constantInfo.SILFnType),
next};
}

SILValue result =
SGF.emitClassMethodRef(loc, selfArg.getValue(), next, methodTy);

// If the fully-uncurried reference is to a generic method, look up the
// witness.
