DenseSet<GlobalValue::GUID> &CantBePromoted) {
bool NonRenamableLocal = isNonRenamableLocal(A);
GlobalValueSummary::GVFlags Flags(A.getLinkage(), NonRenamableLocal,
/* LiveRoot = */ false);
auto AS = llvm::make_unique<AliasSummary>(Flags, ArrayRef<ValueInfo>{});
auto *Aliasee = A.getBaseObject();
auto *AliaseeSummary = Index.getGlobalValueSummary(*Aliasee);
assert(AliaseeSummary && "Alias expects aliasee summary to be parsed");
AS->setAliasee(AliaseeSummary);
if (NonRenamableLocal)
CantBePromoted.insert(A.getGUID());
Index.addGlobalValueSummary(A.getName(), std::move(AS));

{
Function* f = M.getFunction(name);
if (f != NULL)
return f;
GlobalAlias* ga = M.getNamedAlias(name);
if (ga != NULL) {
