hi i want replacing a global variable by a constant value for erase instruction. i had seen the code that as follows for (llvm::GlobalVariable::use_iterator U = gv->use_begin(); U != gv->use_end();--U ) { llvm::Instruction *I = llvm::cast<llvm::Instruction>(U); I->replaceAllUsesWith(constPtr); I->eraseFromParent(); } but i dont know how can declare constptr.

Hi nada, > i want replacing a global variable by a constant value for erase instruction. I'm not sure what you mean exactly. A GlobalVariable has pointer type. Do you want to replace that pointer by a constant pointer? Or is it rather that you want to say that the contents of the memory pointed to by the GlobalVariable is constant, and have all places that load that GlobalVariable
