<div dir="ltr"><div><div><div><div><div><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><br></div><div>Thank you,<br></div><div><br><div>
