[RFC][SDAG] Convert build_vector of ops on extractelts into ops on input vectors
Absolutely. We do it for scalars, so it would likely be a matter of just
extending it.
But that is one example. The issue of extracting elements, performing an
operation on each element individually and then rebuilding the vector is
likely more prevalent than that. At least I think that is the case, but
I'll do some analysis to see if it is so or not.
