You are right, the or disjoint is missing when -mtriple=nvptx64-nvidia-cuda is enabled, I will check this issue。
I found the reason is that the https://github.com/llvm/llvm-project/commit/cd564c6b4638e654edb68acf7f7d985c08edf468 this commit mention LSV optimization is not mature, So the default is to turn this optimization off, so I think for now I can make some small changes on LSV and then continue to let the user choose whether to enable LSV optimization or not.
