Hello, I am trying to replace a pointer argument of a call instruction with another pointer argument( new argument value for the call instruction). What is the best way to do it? I could not find any hint/guidance on the web or LLVM manual. Thanks, -- Abid M.

...ibute (or the Attribute::AttrKind <http://llvm.org/doxygen/classllvm_1_1Attribute.html#aab7ee4b8fd1d3e7e4cea87868855e60e> ) if the function already requires the argument position. When I did a similar process to change the calling instruction in the main function, I used the functions "setArgOperand" and "getArgOperand" which worked just fine, and also the "replaceAllUsesWith", I'm looking for something similar in the case of the function's arguments and their use in the function's body. So the question is: How can I properly replace a function (in my case...
