This patch teaches BasicBlock::print to construct an instance of SlotTracker with the containing function. Without this patch, we dump: *** IR Dump After LoopInstSimplifyPass *** ; Preheader: br label %1 ; Loop: <badref>: ; preds = %1, %0 br label %1 Note "<badref>" above. This happens because BasicBlock::print calls: SlotTracker SlotTable(this->getModule()); Note that this constructor does not add the contents of functions to the slot table. That is, basic blocks are left unnumbered. This patch fixes the problem by switching to: SlotTracker SlotTable(this->getParent()); which does add the contents of the Module and the function, this->getParent(), to the slot table.
