在LLVM中将ConstantDataArray转换为i8 *

Question

Simple question: "I have a ConstantDataArray of type [7 x i8] , how can I cast it to have the i8* type?"

EDIT More Context:

The ConstantDataArray is created as follows:

ConstantDataArray::getString(Fn->getContext(), "Hello", true);

And I have created a LLVM:Function that has an argument with the type coming from Type::getInt8PtrTy(getGlobalContext()) and I want to cast the array to this type, so I can pass it as an argument.

I'm developing a pass

您可以使用IRBuilder的CreateGlobalStringPtr ，它是用于创建全局字符串常量并返回指向其第一个字符的i8*的便捷包装器。
