[PATCH] D75674: [AArch64][SVE] Implement vector tuple intrinsics

[Cullen Rhodes via Phabricator via llvm-commits]

c-rhodes updated this revision to Diff 265514.
c-rhodes added a comment.

Changes:

- Rebased on top of D80139 <https://reviews.llvm.org/D80139> implementing `copyToReg`/`copyFromReg` support for illegal scalable vectors. This enables copying vector tuple types between BBs.
- Removed assert in the lowering of `sve_tuple_get`/`sve_tuple_set` intrinsics checking the tuple is `CONCAT_VECTOR`.
- Vector tuple elements are now extracted with `EXTRACT_SUBVECTOR`.
- Removed target specific calling conv methods from AArch64ISelLowering.
- Updated `test/CodeGen/AArch64/sve-intrinsics-create-tuple.ll` to test extract in different BB.
