...EXTRACT_SUBVECTOR and ISD::INSERT_SUBVECTOR in the context of scalable vectors, so that it is possible to insert/extract a fixed-width vector into or from a scalable vector. (https://reviews.llvm.org/D79806) * We added an intrinsic for vscale and corresponding ISD::VSCALE (https://reviews.llvm.org/D68203) What’s next? ============ The next big thing - and probably the most exciting one - will be auto-vectorization using scalable vectors. Vineet Kumar already did an excellent job describing the styles of vectorization for scalable vectors in his recent proposal (http://lists.llvm.org/pipermail/l...
