Here is my code, (GV is a GlobalVariable*): GV = new GlobalVariable(AI->getType(), false, GlobalValue::InternalLinkage, 0, "temp_glob", &M); I tell it to make it with internal linkage, but when I run the pass it makes them external: %temp_glob = external global [10 x int]* ; <[10 x int]**> [#uses=2] %temp_glob = external global [10 x float]* ;

Hi all, I just walked across an interesting situation in Module::getOrInsertFunction(Name, Type) in the LLVM C API. In my particular case: One of the first things we do is add a global variable named foo which is a [ 100 x i64 ]. Later we add a function void foo(...) unfortunately, when we do the getOrInsertFunction we get back void (...) * bitcast ([100 x i64]* @foo_ to void (...)*)

Following your suggestion, I got some progress. Thanks again. But I am still stuck in some problems. Constant *Cstr = GV->getInitializer(); After that, I tried to use a. for(unsigned i=0;i<Cstr->getNumOperands();++i){...
