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? B

Duplicate Counting Instruction

Hi all, For some certain cases such as histogram we might have duplicate runtime memory dependences, and the current V extension may fail to vectorize such cases. Therefore, I would like to propose du

vrsub.vi, used as negation
2 messages
Is the point of vrsub.vi to provide negation? From a compiler/user perspective, completing the vsub pattern with vsub.vi (even as a virtual instruction) may be a usability enhancement to consider.
