[PATCH] D73549: [Analysis] add optional index parameter to isSplatValue()

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

I don't fully understand how this API is going to be used. The current API makes sense to me (are all elements in the vector the same?) but the new one is unclear, especially for the case where no shufflevector is involved. If I have a splat constant, which index does the value come from?

Do you already have a followup patch that uses this API that you could share?
