[PATCH] D100107: [AArch64][SVE] Combine add and index_vector

[Sander de Smalen via Phabricator via llvm-commits]

sdesmalen added a comment.

Thanks, that looks quite neat. Can you also add a few tests when there is >1 use of the stepvector (e.g. using the stepvector in two adds), so we can test the fold indeed doesn't happen?
One test for each of the instructions should be sufficient.
