     6== Horizontal Halving Operations ==
    57
    68These operations generally have the form `r = hsimd<w>::op(a, b)` for each
     
    3638arguments c,,2i,, and c,,2i+1,,.
    3739
     40== Horizontal Bit Selection ==
     41
     42The operation `n = hsimd<w>::signmask(a)` packs together the high (sign) bits of
     43each ''w''-bit field of `a`, returning the result as an ordinary integer value.
