One could do sum128 with just 8 registers by performing the adds ASAP,
i.e., for sum32

vmovapd   zmm0,  [rbx]
vmovapd   zmm1,  [rbx+64]
vaddpd  zmm0, zmm0, zmm1
vmovapd   zmm1,  [rbx+128]
vmovapd   zmm2,  [rbx+192]
vaddpd  zmm1, zmm1, zmm2
vaddpd  zmm0, zmm0, zmm1
; and then the Horizontal sum

And you can code this as:

vmovapd   zmm0,  [rbx]
vaddpd  zmm0, zmm0, [rbx+64]
vmovapd   zmm1,  [rbx+128]
vaddpd  zmm1, zmm1, [rbx+192]
vaddpd  zmm0, zmm0, zmm1
; and then the Horizontal sum

>

>vaddpd ymm4, ymm3, ymm2
>
>vhaddpd xmm0, xmm4, xmm4

Instead of doing the horizontal sum once for every sum128, it might be
more efficient (assuming the whole thing is not
cache-bandwidth-limited) to have the result of sum128 be a full SIMD
width, and then add them up with vaddpd instead of addsd, and do the
horizontal sum once in the end.

But if the recursive part is to be programmed in Forth, we would need
a way to represent a SIMD width of data in Forth, maybe with a SIMD
stack.  I see a few problems there:

* What to do about the mask registers of AVX-512?  In the RISC-V
  vector extension masks are stored in regular SIMD registers.

* There is a trend visible in ARM SVE and the RISC-V Vector extension
  to have support for dealing with loops across longer vectors.  Do we
  also need to support something like that.

For the RISC-V vector extension, see
<https://riscv.org/wp-content/uploads/2024/12/15.20-15.55-18.05.06.VEXT-bcn-v1.pdf>

One way to deal with all that would be to have a long-vector stack and
have something like my vector wordset
<https://github.com/AntonErtl/vectors>, where the sum of a vector
would be a word that is implemented in some lower-level way (e.g.,
assembly language); the sum of a vector is actually a planned, but not
yet existing feature of this wordset.

An advantage of having a (short) SIMD stack would be that one could
use SIMD operations for other uses where the long-vector wordset looks
too heavy-weight (or would need optimizations to get rid of the
long-vector overhead).  The question is if enough such uses exist to
justify adding such a stack.
