Hi,<div><br></div><div>I worked in llvm to get some information from live variable analysis.</div><div>If the live range of one variable interferes with another, we could record the related two variables into a pair. For example, with a function with local variables 'a', 'b', 'c', 'x' and 'y', the pair set { (a, b), (b,c), (x,y)} indicates that 'a' interferes with 'b', 'b' interferes with 'c', and 'x' interferes with 'y'.</div>
<div><br></div><div>The question is: How can I get this information (maybe in other forms) by using llvm to compile a program?</div><div><br></div><div>Could anyone help me?</div><div>Thanks in advance. </div><div><br>-- <br>
Best regards,<div><br></div><div>Li Qingan</div><br>
