...basic block (removals are very comomn in peephole optimizers and insertions in register allocators) 2) After an insertion all std::vector<MachineInstr*>::iterators are invalidated. 3) After an erase all std::vector<MachineInstr*>::iterators after it are invalidated. After ilistification, MachineBasicBlock uses an ilist<MachineInstr> data structure (include/Support/ilist). The ilist (short for intrusive list) is a lot like std::list but with the additional benefit of allowing the conversion of a MachineInstr* to an ilist<MachineInstr>::iterator with no cost whatsoev...
