Fwd: I cannot change value of global variable in LLVM IR using IRBuilder
I don't think it's the same problem as you described. By printing I meant
calling printf function and passing my global variable as one of the
arguments.
My code:
Instruction* InstructionVisitor::incrementGlobalKey(Instruction* I) {
IRBuilder<> Builder(I->getContext());
Builder.SetInsertPoint(I->getNextNode());
GlobalVariable* key = I->getModule()->getNamedGlobal("globalKey");
if (key) {
LoadInst* load = Builder.CreateLoad(key);
Value* inc = Builder.CreateAdd(load, Builder.getInt...

Fwd: I cannot change value of global variable in LLVM IR using IRBuilder
Hi Everyone,
I'm quite new to LLVM and I want to update value of global variable in LLVM
IR. I created new global variable in ModulePass:
bool runOnModule(llvm::Module &M) {
IRBuilder<> Builder(M.getContext());
Instruction *I = &*inst_begin(M.getFunction("main"));
Builder.SetInsertPoint(I);
M.getOrInsertGlobal("globalKey",
