For example, when I have a basic block like: bb1: ; preds = %bb load i32* %i, align 4 ; <i32>:11 [#uses=2] load i32* %n_addr, align 4 ; <i32>:12 [#uses=2] icmp slt i32 %11, %12 ; <i1>:13 [#uses=2] cloning it gives something like: bb1_clone: ; preds = %entry load i32* %i, align 4 ; <i32>:28 [#uses=0] load i32* %n_addr, align 4 ; <i32>:29 [#uses=0] icmp slt i32 %11, %12 ; <i1>:30 [#uses=0] Since the temporaries referred to in the cloned icmp instruction are still those created in bb1, I get the "Instructi...
