[LLVMdev] replacing a global variable by a constant

[neda 8664]

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.
