...is necessary, since he wants to replace the function. He only needs to create the new function and splice in the body of the old one. Gabriel: look at Function::getBasicBlockList() and iplist<>::splice(iterator, iplist). Something like Function *NewF = Function::Create(NewFnType, OldF->getLinkage()); NewF->getBasicBlockList().splice(NewF->begin(), OldF->getBasicBlockList()); NewF->takeName(OldF); OldF->eraseFromParent(); is probably what you're looking for.

...y working on a science project and implemented a FunctionPass that clones a function (more precisely a constructor of a struct/class) and adds a parameter. First, we create a new function with a new function type, which includes the newly added parameter: Function *NF = Function::Create(NewFTy, F.getLinkage(), F.getName() + "Cloned", F.getParent()); and after setting up the ValueToValueMapTy, we use the CloneFunctionInto method to clone the function body CloneFunctionInto(NF, &F, Map, true, Returns, "Cloned"); The code seems to work as intended, but when we try to emit deb...

Hi All, I need to call global variable by its name from the following code for(Function::iterator i=F->begin();i!=F->end();++i) { BasicBlock*Bb =&*i; GlobalVariable* GV = new GlobalVariable(type,false, F->getLinkage(),0, "F$"+Bb->getName()); GV->setInitializer(Constant::getNullValue (typ)); GList.push_back(GV); } Could I solve that by mapping the global variables in Stringmap? I need to identify the global variable with its name in the IR to be able to load and store its values....

Hi! I have a module containing a constant e.g. @input = global %0 zeroinitializer, align 16 when I copy the global into another module I use newGlobal->copyAttributesFrom(global); but the new module now has @input = external global %0, align 16 i.e. the zeroinitializer is missing. how do I set it or copy it from the other global? -Jochen

...response to your earlier question, not all constants are safe to use in a different module. So simply copying the initializer may be unsafe... Note that linkage and constness don't seem to count either. newGlobal->setConstant(global->isConstant()); newGlobal->setLinkage(global->getLinkage()); All three of these can also be passed to the constructor for newGlobal, by the way. According to the comment on GlobalValue::copyAttributesFrom() (as well as its GlobalVariable override) this seems to be the defining characteristic that qualifies them as "attributes"; it considers an...

Hi, I've been able to link ioquake, but not without a small modification to lib/Linker/LinkModules.cpp:427 where I had to add: } else if (Dest->hasExternalLinkage() && Src->hasExternalLinkage()){ LinkFromSrc = true;//overwrite old value LT = Src->getLinkage();//use src linkage The reason is that two files both had a global function pointer variable (due to #include's): void ( *alEnable)( ALenum capability ); which got translated to: @alEnable = globale void (i32)* null Linking these resulted in an error (lib/Linker/LinkModules.cpp's o...
