The RISC-V vector extension introduces SIMD instructions to RISC-V, however many known patterns in other SIMD extensions don't translate 1-to-1.
Therefore, the goal of this document is to share various RVV tips and tricks as well as some common pitfalls.
It should help people familiar with other SIMD ISAs to figure out how to efficiently express many common patterns in RVV.
We collected these paradigms while porting various software and algorithms to RVV.
