    <div>Dear Petsas,<br>
      <br>
      For analyzing indirect function calls, your best bet is probably
      to use the CallGraph analysis pass that is part of DSA.  DSA is
      included in the poolalloc code; you can get directions on
      downloading poolalloc from the SVA web page:
      <a href="http://sva.cs.illinois.edu/docs/Install.html" target="_blank">http://sva.cs.illinois.edu/docs/Install.html</a>.<br>
      <br>
      The release_32 branch works with LLVM 3.2.  I think mainline
      poolalloc was recently updated to work with LLVM 3.4.<br></div></div></blockquote><div><br></div><div>Do you know where I can find mainline poolalloc so as I can compile it with<br></div><div>LLVM 3.4 ?<br><br></div>

                    <div>Dear all,<br>
                      <br>
                    </div>
                    I would like to keep track of all the indirect calls
                    that may caused from function<br>
                  </div>
                  pointers inside a program. I need this in order to be
                  able to construct the control<br>
                </div>
                flow graph of all the indirect calls, that is which
                function is legal to call another<br>
              </div>
              function.<br>
              <br>
            </div>
            Is there a module that implements this functionality in
            llvm? If not, is there a way to<br>
            do it? Maybe through implementing a pass. I am new to llvm.
            Could you suggest me<br>
          </div>
          <div>a way to start doing this? Perhaps the llvm intermediate
            code can help me on this.<br>
          </div>
          <div>Do you know where this code is being produced? or what
            files or passes do I have<br>
          </div>
          <div>to modify for this?<br>
            <br>
          </div>
          <div>Until now I have used this command to produce and study
            the llvm bitcode for a test<br>
            program:<br>
            clang -S -emit-llvm fpointers.c -c -o fpointers.bc.text<br>
