[llvm-dev] Setting a function in a module to extern

[Gaier, Bjoern via llvm-dev]

But in my module this function already exist… I first want to delete it but without also deleting the calls to it…

I think you just need to llvm::Function::Create(Type, Linkage, Name, Module) it and not add any basic blocks to it.

Hello again,



as mentioned in a different mail, I’m a beginner with the LLVM and writing a JIT-Client under Windows.



In my llvm::Module I have a certain function – now I want to delete this function, but keep all the calls and references to it. I kind of want to set the function to an external function.

Is this possible?



Kind greetings

Björn
