How to initialize a string and store value in llvm IR

How can I initialize a local string in llvm IR. I know how to do Int using AllocaInst and StoreInst. Is there similar ways to initialize a string?

Solution

  • First, you create a constant GlobalVariable that holds a byte array representing your string. Any GlobalVariable is of pointer type, so you can use it in your function right away.

    For example, you can use getelementptr instruction in conjunction with load to access string characters.
