llvm dev - Jul 2012 - [LLVMdev] Non-tail calls

Hi all.

I am using LLVM to develop a procedural language.  Can anybody point me to an
example that uses CreateCall for a non-tail call?  I am having trouble doing
anything with the return value from the call besides returning it immediately.

i.e. Passing the CallInst created by CreateCall to CreateRet is working fine,
but I am having trouble storing the returned value in a local variable or
passing it to another call.

Adelle.

Sounds like you are using the C++ API.

You can store the value like: Value *val = Builder.CreateCall(...);

Then, for example, you can do: Builder.CreateAdd(val, val);

Or whatever else you want to program!
