[LLVMdev] Assertion in Function.cpp when linking modules
...dy
I am having a hard time figuring out the following problem:
I am porting a library that uses LLVM 2.5 from Linux to Windows (LLVM compiled with cmake/MSVC, llvm-g++ pre-built binaries).
Compilation works fine, but at runtime, I encounter the following assertion:
Assertion failed: FunctionType::isValidReturnType(getReturnType()) && !isa<OpaqueType>(getReturnType
()) && "invalid return type", file .\Function.cpp, line 164
This happens somewhere in "LinkInModule" when trying to link two loaded .bc-files (generated by llvm-g++).
The weird point:
The assertion fires...

[LLVMdev] LangRef/implementation inconsistency: What is the intended constraint on function return types?
...a function type is a first class type or a void type."
<http://llvm.org/docs/LangRef.html#id14>
and also, contrarily,
"<returntype>‘ is any type except label."
<http://llvm.org/docs/LangRef.html#id15>
On the other hand, the actual implementation of
FunctionType::isValidReturnType opines that:
bool FunctionType::isValidReturnType(Type *RetTy) {
return !RetTy->isFunctionTy() && !RetTy->isLabelTy() &&
!RetTy->isMetadataTy();
}
These definitions are mutually incompatible. What is the intended definition?

[LLVMdev] Newbie question: LLVM IR, printf, and varargs
...!(Ty = dyn_cast<FunctionType>(PFTy->getElementType()))) {
// Pull out the types of all of the arguments...
std::vector<Type*> ParamTypes;
for (unsigned i = 0, e = ArgList.size(); i != e; ++i)
ParamTypes.push_back(ArgList[i].V->getType());
if (!FunctionType::isValidReturnType(RetType))
return Error(RetTypeLoc, "Invalid result type for LLVM function");
Ty = FunctionType::get(RetType, ParamTypes, false);
PFTy = PointerType::getUnqual(Ty);
}

[LLVMdev] Newbie question: LLVM IR, printf, and varargs
Whoops... Seems I forgot the asterisk (*) after the cast. Or something.
Because I did insert the cast and it didn't work. But NOW it works.
Thank you for spending some time on this - and also for presenting the
solution.
