Hello, and thanks for your time reading this. I'm trying to test interactions of my dataset, in which the all of the factors are within the same column. Type Vol 1 CMass -4.598 2 BBack -4.605 3 BMass -4.602 4 CMass -4.601 5 CBack -4.605 6 CMass -4.604 7 CMass -4.602 8 CMass -4.604 9 CBack -4.605 10 BBack -4.503 11 CMass -4.605 Im attempting to determine the interaction effects of B or C

Hi I currently would like to find out the signedness of a instruction. But looking at the CBackend, it looks as if it is not that simple? So i have two questions: Is there an easier way than guessing as it is done in the CBackend? Is there a reason for that signedness is not part of the instruction type? Best regards ST

...hat signedness is not part of the instruction type? A lot of LLVM integer instructions don't naturally have a sign. For example, signed addition and unsigned addition are exactly the same operation in two's complement, so the LLVM assembly doesn't bother to encode the signedness. The CBacked "guesses" because the necessary information is completely gone. If you haven't looked at http://llvm.org/docs/LangRef.html, I'd suggest taking a look; it precisely states the semantics of all the LLVM instructions and intrinsics. -Eli
