Okay, thank you for your advice. I'll remove `DisableFramePointerElim()` and refactor CanEliminateFrame like this:
`bool CanEliminateFrame = !(requiresAAPCSFrameRecord(MF) && hasFP(MF)) ||
      !(MF.getFunction().hasFnAttribute("frame-pointer") && MF.getFunction().getFnAttribute("frame-pointer").getValueAsString() == "all");`
