llvm dev - Apr 2014 - [LLVMdev] Replacing all uses of a StructType

Hello,

I'm trying to replace all uses of StructType A with StructType B. I've
created a class that inherits from ValueMapTypeRemapper, returns B whenever
A is passed to it, and used this class with the CloneFunctionInto function.

Is there a way to clone a function into itself? Currently I've got
duplicates of most of my functions, which is fine, but I don't need to
duplicate main, so I'm looking for a way to replace all uses of A with B
inside main.

Thanks,
Peter

You can clone main() into a new function, the rename main() to something 
else (e.g., oldmain()), and then rename your new function main().  In 
fact, I think Value * now has a takeName() method that allows you to do 
the renaming with a single method call.
