[PATCH] D121677: [RISCV] Return Invalid cost in getGatherScatterOpCost instead of crashing for scalable vectors

[Liao Chunyu via Phabricator via llvm-commits]

liaolucy added a comment.

I try to support scalable vectors in getGatherScatterOpCost, but I don't know how to support scalable vectors.

https://reviews.llvm.org/D115143 SVE adds on an overhead cost for gathers and scatters, which is a rough estimate based on performance investigations.

Does RVV add similar values？
