...t one is that I can not change the type of the global value. Let say that I have the following variable: @.str = private unnamed_addr constant [6 x i8] c”Test0A\00", align 1 How can I change the ”Test0A\00” to ”OtherTest0A\00”. Is this possible? I know that you can change the initializer with setInitializer but the global value’s type will not be the same. For now, the only way I found was to create a new global value and to change all theses uses. The second problem that I have is with the function Verifier::visitGlobalVariable. Sometimes, the verifier tells me that the initializer type does no...

...<< gI->getName()<<gI->getInitializer(); } With *gI, I could get all string With gI->getName, I could get the global variable name. With gI->getInitializer(), I could get the init value for the GV. Next, what I want to do is to modify the value of the GV, and I tried to use setInitializer(), but I don't know to do it. setInitializer() need contant parameter. I tried several ways, but I failed. As you said, I can do it like in C level. For C, if I can get the address of the GV, I can read the value and do XOR and then write it back. But for this case, I don't know how to...

...this to repalece an argumrnt of an instruction like: I->setOperand(someArgumentIndex,pConst); However, getGetElementPtr returns a pointerType, which holds the actual type as sub_type. This is a problem when I want to use the data from one global for the initializer of another pGvar->setInitializer(__NeedsAFloatTy_here__); //not pointerTy So what I'm trying to do is copy some data-fields of one global to another. I know the 'index-trace' used in getGetElementPtr, but I need the actual type, not 'covered' by a pointerType. Thank You! Alexander

...But if I rearrange the statements to: @a2 = global i8 addrspace(1)* @a @a = addrspace(1) global i8 0 then I get an ugly assertion failure: Assertion failed: (InitVal->getType() == getType()->getElementType() && "Initializer type must match GlobalVariable type"), function setInitializer, file /Users/jholewinski/projects/llvm/src/llvm/lib/VMCore/Globals.cpp, line 168. Looking at the debugger, I see that InitVal (the initializer for @a2) has type i8*, which looks incorrect as it drops the addrspace from the definition of @a. Before I go too far into this, should this IR work?...

SDUse::setInitial should initialize List to null in your patch. You're probably seeing random uninitialized data noise without that. (Though valgrind wouldn't notice this because of the aggressive reuse of allocated memory.) Also, the replacement getOperandNo is returning the index in the use list, rather t...

Hi all, I am newbie for llvm. I just create a global variable, there are some statements in my pass like: LoadInst* int64_64 = new LoadInst(pthreadPID, "", false, OptAplusOne); int64_64->setAlignment(8); int64_64->dump(); LoadInst* int32_65 = new LoadInst(gvar_int32_myFlag, "", false, OptAplusOne); int32_65->setAlignment(4);

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. Thanks -- * Rasha Salah Omar Msc Student at E-JU...

Hi all, suppose I would like to change the initial value of a global. Is the supposed way to change the initializer via const_global_iterator I I->setInitializer(newOne) ? afaik, newOne is a constant - right? Is the original Initializer automatically purged or do I need to delete it? thanks Alex

...?  If so, what do I need to do to give the variables an initial value and make sure that the Global Variable Optimizer can recognize that these variables can indeed be optimized into constants? You'll essentially have to do it yourself, I think, but it's not hard: just call GlobalVariable::setInitializer and GlobalVariable::setConstant on the globals in question once the bitcode is loaded, then run instcombine to propagate the constants. I don't think globalopt has enough information in your situation to do the optimization in question. -Eli
