The ternary isn't guaranteed to be branchless. In your case it should almost always be on a modern compiler, but it really shouldn't be present in what one would call branchless code.
replyYou could rewrite it to
reply int* ptr = ((v != 0) * lwr) + ((v == 0) * rwr);
Does any standard library have a glsl-like select(condition, true_val, false_val) that is more or less guaranteed to correspond to a csel?
