Suppose I have in my CFG (among others) two basic blocks A and B, with an edge from A to B. I need to do the following: * get the set S of live values across that edge * map each of them to another value (S->S') * replace - in B and its successors - all the uses of values in S with the mapped values (S') Does LLVM provide an easy way to do this (because I can't
