[PATCH] D118459: [ISEL] Canonicalize STEP_VECTOR to LHS if RHS is a splat.

[Paul Walker via Phabricator via llvm-commits]

paulwalker-arm added a comment.

Just wanted to say that I'm not suggesting this patch implements the `binop(splat(x), not_splat(y))` -> `binop(not_splat(y), splat(x))` idea in one go.  I just think that if we agree that it's ultimately the better canonical form then I'm happy to accept this patch as a step in the right direction to unblock your current work and we can fix the rest up later (well sooner rather than later :) )
