Fix compilation with what?
I'm not familiar with the sobel algorith/function so I can't say whether
the code is correct. However those constants are only dword sized and
that is how you do a memory broadcast with avx512(icl). Furthermore
testing your change on an icl system results in a failure in checkasm.
So what program and what version fails to assemble that?
