Hello
With LLVM 4.0 my code is being compiled correctly. but with LLVM 7.0.1 I am getting following error;

llvm-7.0.1.src/include/llvm/IR/Module.h:356:43: error:
no matching constructor for initialization of 'SmallVector<llvm::Type *,
sizeof…(ArgsTy)>’
SmallVector<Type*, sizeof…(ArgsTy)> ArgTys{Args…};

What is the reason?

Please help.

Thank You

Due to this I am unable to do my task with LLVM7.0.1. How to solve this?

Please help.

Hi,

It would be great if you can attach your source code and complete error message.

But one of the possible reasons might be some API with var-args, Module::getOrInsertFunction for example(http://llvm.org/doxygen/classllvm_1_1Module.html#a9c362a6df0554c3d9355aadfa67a1914 ), do not use NULL to mark the last argument anymore. So SmallVector cannot deduct the type for NULL, which would be deducted as unsigned int instead of llvm::Type* as originally expected.

Hi,

Yes I think the source code confirm my assumption in my last email: the Module::getOrInsertFunction in line 53 shouldn’t use NULL to terminate the var-args list anymore.
