[PATCH] D146218: [AArch64][CodeGen] Lower (de)interleave2 intrinsics to ld2/st2

[Graham Hunter via Phabricator via llvm-commits]

huntergr updated this revision to Diff 532846.
huntergr added a comment.

- Removed pointer casts. I based the new code a little too closely on the existing shufflevector lowering code.
- Fixed offset calculation to include the interleave Factor.
- Also fixed another bug -- BaseAddr was overwritten with the new GEP value, which increases the offset for later memory operations instead of using the size per load/store. All GEPs now use the original pointer as a base.
