Pictures for vec_sum2s, vec_sum4s, and vec_sums
PC requests pictures for these.
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
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?
