    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. + For example:

    + +
    +
    +GlobalVariable *GV = .. ;
+Module *M = GV->getParent();
+
+M->getGlobaleList().erase(GV);
