Is there a way to avoid tree destruction? Maybe through a flag? If not, what I need is in the hook, to know if the caller, calls any other functions besides the one we are evaluating the sibcall to. This would be easy with the tree as we would only need to walk the tree and find CALL_EXPR different from the one we get in the argument for the hook. Without the tree, I don't even know if this is possible since we don't have the complete RTL yet, right? Do you have any suggestion? > Richard. > -- Paulo Jorge Matos - pocmatos at gmail.com http://www.pmatos.net
