yonghong-song added a comment.
Looks like stripPointerCasts() is enough to make it work (no null Function
pointer any more). This is consistent with
llvm::Constant *CodeGenModule::GetOrCreateLLVMFunction(
StringRef MangledName, llvm::Type *Ty, GlobalDecl GD, bool ForVTable,
bool DontDefer, bool IsThunk, llvm::AttributeList ExtraAttrs,
ForDefinition_t IsForDefinition) {
const Decl *D = GD.getDecl();
...
// Make sure the result is of the requested type.
if (!IsIncompleteFunction) {
assert(F->getFunctionType() == Ty);
return F;
}
llvm::Type *PTy = llvm::PointerType::getUnqual(Ty);
return llvm::ConstantExpr::getBitCast(F, PTy);
}
It either returns a Function, or a Function-Casting-To-ConstantExpr.
