Right, I'll just replace "registers" with "operands" then. Ok? also to emit such a permutation. In the former case @var{in0}, @var{in1}\n\ and @var{out} are all null. In the latter case @var{in0} and @var{in1} are\n\ the source vectors and @var{out} is the destination vector; all three are\n\ -registers of mode @var{mode}. @var{in1} is the same as @var{in0} if\n\ +operands of mode @var{mode}. @var{in1} is the same as @var{in0} if\n\ @var{sel} describes a permutation on one vector instead of two.\n\ \n\ Return true if the operation is possible, emitting instructions for it\n\ Andreas
