Vector-scalar instructions
Sorry for what may be a question with an answer that may be obvious to those that have been at all the meetings:
Have the vector-scalar instructions (.vs) been eliminated from the vector extensions? By this, I mean where the scalar comes from vector element zero. I only see things like .vx for the arithmetic instructions, where the scalar comes from any of the general-purpose “x” (or alternatively, the floating-point) registers in my reading of the latest version of the specification.

Hi Rich, The reduction operations retain the `.vs` suffix: https://github.com/riscv/riscv-v-spec/blob/master/v-spec.adoc#16-vector-reduction-operations Best, Nick Knight On Wed, Jul 1, 2020 at 10:23 AM Richard Newell via lists.riscv.org <richard.newell=microchip.com@...> wrote:
