<div dir="ltr"><div><div><div>But I don't want to map only basic blocks, I need too to map the edges "the whole CFG of the function"<br></div><div><b>Yes. First you create simple methods to create an integer graph and to addEdge. Then, two types of edges: between basic blocks inside a function (you can use LLVM succesors) and between functions (use Call/Return/ and identify the pairs (Callee/Caller), so you can add edges between the correspondent basic blocks from different functions.</b><br>
</div>Save
the CFG of the function in another memory address and call it for
example orgCFG and change the CFG by referencing to the orgCFG<br></div><div><b>So first make all the changes on orgCFG (the integers CFG) and then, in another transformation pass: modify your old CFG (by removing./adding, which I don't recommand) or add metadata (keeps information about the changes you want to make, but you don't actually make)</b><br>
