Cancelling vector TG meeting this week
Apologies for late notice, but I’m going to cancel the vector TG meeting today. I still have a backlog of settled issues to incorporate in document, and do not have a set of topics worked up for this

Integer Overflow/Saturation Operations

Vector-widening multiply & accumulate instructions: These instructions, signed or unsigned, will quickly overflow in even simple cases. Given absence of flagging (e.g. OVERFLOW), a saturating version

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.
