[PATCH] D41126: [SelectionDAG] Fixed f16-from-vector promotion problem

[Tim Renouf via Phabricator via llvm-commits]

tpr added a comment.

It can't handle it because it is a fp16_to_fp whose input is v1i16 and result is f32. My theory was that that is illegal, and I needed to fix where that was being generated, which is what I have done.

Do you think my theory is wrong?
