[PATCH] D79587: [CodeGen][SVE] Legalisation of extends with scalable types

[David Sherwood via Phabricator via llvm-commits]

Hi @efriedma, is there a target-independent equivalent of SUNPKHI? From a quick glance at the codebase where X86 uses ISD::SIGN_EXTEND_VECTOR_INREG it seems vector shuffles are still required for the Hi part, which is fine for fixed length vectors I guess.
