<div style="line-height:1.7;color:#000000;font-size:14px;font-family:arial"> <br>Hi all,<br>I want to run a function pass on a certain .bc file. In the process, the pass will insert a check function into the .bc file.<br><br>I know the .bc file is regarded as a module in LLVM. So, there are two basic steps needed to be done,<br>1, Use the "getOrInsertFunction"API to add a declaration of the extern "check function".<br>2, Use the "insertBefore"API to insert the CallInst into the right position.<br><br>My problem is about the step 1. How can I get the handle of the .bc file (Probably is a Module*)? so I can <br>declare the extern function like<br>// insert the " i32 @fib(i32 )" to the module M<br>Function *FibF =<br> cast<Function>(M->getOrInsertFunction("fib", Type::getInt32Ty(Context),<br> Type::getInt32Ty(Context),<br> (Type *)0));<br>How can I get the "M" of the .bc file??????<br><br>Any help~<br> <br><div>--<br><div>
