Description

I think https://github.com/riscv-non-isa/rvv-intrinsic-doc is the place to get them, v1.0 was ratified on April 25 2025.
It would be really nice to get them into standard library now that RISC-V hardware becomes more common and there are various RISC-V-based VMs out there (for example in blockchain space).

Research direction

Start by reviewing the referenced rvv-intrinsic-doc specification and stdarch's existing vendor-specific APIs. Determine the integration entry points and test coverage needed for RISC-V Vector Extension v1.0; done means the relevant intrinsics are available in the standard library with passing tests.
