Which optimizer would remove duplicate, or unneeded loads? In my generator I end up having a lot of the same load. For example here I keep loading "@pt" which will always be the same value. %16 = load %1** @pt, align 8 %17 = getelementptr inbounds %1* %16, i64 0, i32 2, i32 0 %18 = load i32* %17, align 4 call void @trace_integer(i32 %18) %19 = load %1** @pt, align 8 %20 =
