The second example for vec_sum4s gets saturation wrong, since this is signed arithmetic. The third column for r should say it is saturated, and the fourth column result should be 00000000.

The web version has the bullets located oddly with respect to the tables.

For vec_sums, b and r are in italics, rather than boldface.

Otherwise ok, please resubmit.

I suppose the weird bullets are an artifact of github, not the examples themselves...

Those two columns in the vec_sum4s are indeed wrong. The fourth column should indeed be 00000000, but the 3rd column should actually be 7FFEFFFF because 8421 is negative. However, that's not what I intended, and curse me for not acutally writing and running a test.
I'll fix it up. I don't acutally like the 3rd column as a useful example.
I'll resubmit in a bit.

Oh, the bullets are not part of the images. I put the images in a list in the GitHub comment. I have not done this before, but this commit hit multiple sections. I thought, mistakenly, that it would be clearer. :-/

Looks good, with one nit. vec_sum2s is missing the horizontal line at the bottom of the frame, in both PDF and web versions. Can you please fix?

Weird. I think my pictures were both coincidentally poorly captured, omitting the bottom border. Unless you built the changes and see the same thing, I think it was just a poor image capture. I've recaptured the images below:
