It creates a new function and uses CloneFunctionInto() to create a copy of the instructions in the old function in the new function. The old function can be removed afterward if desired. I'm not sure if the code below would work. I don't see a mechanism that updates instruct...

...unction 3) Find all calls calling the old function and replace them with calls to the new function. This is necessary because a function cannot have its type changed once it has been created. Automatic Pool Allocation adds parameters to functions (which is similar to what you need to do). See MakeFunctionClone() in poolalloc/lib/PoolAllocate/PoolAllocate.cpp in the poolalloc project.

Hello All, I want to change the return type of a function in a Pass(in a module Pass). I dont want to change any of the arguments of that function. Assume that, I can handle the returning values properly inside the function. Please guide me how to do this ? -- Regards, Gokul Ramaswamy, Graduate Student, Department of CSE, IIT Bombay http://www.cse.iitb.ac.in/~ramaswamy --------------

Check out http://llvm.org/svn/llvm-project/poolalloc/trunk and look for the code that does this in lib/PoolAllocate/PoolAllocate.cpp in the MakeFunctionClone() method. -- John T. > > Thanks in advance, and best regards, > Gabriel -------------- next part -------------- An HTML attachment was scrubbed...

Hi all, I am trying to extend a FunctionType to include new parameters. In particular, I want to ensure that the main function has been declared with both argsc and argsv. However there seems to be no easy way to accomplish this: llvm::Function::getFunctionType() returns a a reference to a const object, while modifying only the argument list yields an error during verification since the
