[LLVMdev] How doesn't llvm generate IR for logical negate operation
Thanks, Bruce. So, what is the easiest way to check if there is any bit set
to 1 in a <N x i1> vector type? I used bitcast instruction to cast it into
"iN" first and them compare iN to 0. Do you have a better way to do it?
Thanks again.
