Deleting a global variable from a module is similar to deleting an -instruction. First, you must have a pointer to the global variable that you wish - to delete. Second, you must have a pointer to the module the global variable - belongs to. You use the pointer to the module to get its list of global - variables and then use the erase function to remove your global variable. +
Deleting a global variable from a module is just as easy as deleting an +Instruction. First, you must have a pointer to the global variable that you wish + to delete. You use this pointer to erase it from its parent, the module. For example:
GlobalVariable *GV = .. ; -Module *M = GV->getParent(); -M->getGlobaleList().erase(GV); +GV->eraseFromParent();
