This is precisely the sort of transformation that, in my opinion, should be separate from the hardware intrinsics. I mentioned this specific case earlier in the thread (I think; maybe it went to a private mail). The documentation should quote you above, instead of being general and vague (lots of "mays", for example, in the current text). Perhaps we need to have a clearer name for the option, -funsafe-transformations, anyone? I may want to use a hardware intrinsics, but not want those transformations. ..Scott
