afonso360 opened PR #6602 from afonso360:riscv-simd-extra-mul to bytecodealliance:main:

:wave: Hey,

This PR Implements sqmul_round_sat, we have a dedicated instruction for this so it's fairly straight forward.

Additionally it also adds some variants of the existing multiplication instructions that splat one of the inputs. These were originally added before we had support for VX opcodes, and I've just noticed they were missing.

This looks good to me! The vx variants for some of the vector ops seem extremely useful!
