Why do we only have 2/4/8, I think we should have 2/3/4/5/6/7/8
No idea why I posted that (wrong) version, I used it for
some testing locally. Attached is the proper version, still
called it v3...

Subject: [PATCH v3] RISC-V: Add initial cost handling for segment
loads/stores.
This patch makes segment loads and stores more expensive. It adds
segment_permute_2 as well as 3 to 8 cost fields to the common vector
costs and adds handling to adjust_stmt_cost.
gcc/ChangeLog:
* config/riscv/riscv-protos.h (struct common_vector_cost): Add
segment_permute cost.
* config/riscv/riscv-vector-costs.cc (costs::adjust_stmt_cost):
Handle segment loads/stores.
* config/riscv/riscv.cc: Initialize segment_permute_[2-8] to 1.
So where do we stand with this? Juzhe asked it to be rebased, but I
don't see a rebased version in my inbox and I don't see anything that
looks like this on the trunk.
