Hi Ciara Loftus,

We may need some= legacy support for the SSE path for earlier systems. Or it will not be a p= roblem ?=C2=A0
As you specified that modern x86 systems all support AVX2= , if not AVX-512.
Still, we might need some type of support for the SSE= path.


Best Regards,

loss, as in the rare cases where the SSE path would have been used in
the absence of AVX2 or AVX-512, the fallback scalar path will be used
which has feature parity with SSE.
