https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111337 --- Comment #8 from Robin Dapp --- Yes, I doubt we would get much below 4 instructions with riscv specifics. A quick grep yesterday didn't reveal any aarch64 or gcn patterns for those (as long as they are not hidden behind some pattern replacem

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111337 --- Comment #9 from JuzheZhong --- So, should we support this pattern in RISC-V backend ? Or adjust gimple-isel to generate these 4 STMTs naturally?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111337 --- Comment #10 from Robin Dapp --- I would be OK with the riscv implementation, then we don't need to touch isel. Maybe a future vector extension will also help us here so we could just switch the implementation then.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111317 --- Comment #1 from Robin Dapp --- I think the default cost model is not too bad for these simple cases. Our emitted instructions match gimple pretty well. The thing we don't model is vsetvl. We could ignore it under the assumption that it is
