Direct calls are not a problem, but currently I also need to retrieve the name of the function in the case of virtual method calls. For example:<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>struct A {<o:p></o:p></p><p class=MsoNormal> A() {}<o:p></o:p></p><p class=MsoNormal> virtual foo() {}<o:p></o:p></p><p class=MsoNormal> virtual ~A() {}<o:p></o:p></p><p class=MsoNormal>};<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>int main() {<o:p></o:p></p><p class=MsoNormal> A* a = new A;<o:p></o:p></p><p class=MsoNormal> a->foo();<o:p></o:p></p><p class=MsoNormal>}<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>In the pass, I can determine the name of the indirect call by using CallInst::getCalledValue(), but that doesn’t give any information on the actual method that is being called, which should be foo(). The only “name” I can get is the type of the class, in which this case is class.A.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Is there any way I can get the name of the virtual method (foo) that is being invoked? It isn’t in the bitcode except for when it is defined. I tried taking a look at the whole-program-devirt source but can’t find where they are actually finding the names of the functions when building the virtual tables for each class.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I would greatly appreciate any help on this and if it is possible at all.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks,<b><span style='font-size:10.0pt;font-family:"Tahoma",sans-serif;color:#0B5394'><o:p></o:p></span></b></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Ben Fu <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
