Yes, my code only handles some cases, but others are handled by the core part
of
tree-vect-generic.cc. I just take care of some special cases up front. So, V8DF
-> V8SI
is still split into smaller vectors for SSE.
And for SSE, I have
another patch to expand the available direct optab environment with
ix86_expand_vec_perm_const_1 (...). This patch hasn't been sent yet.
I will sending it out together after I modify this patch. This gives an overall
view
of my changes to this function.

Yes, my code is based on vectorizable_conversion(...). I will consider to split
the function
and define some new function like your advises to make my code more common.
