zVector instructions missing optional alignment mask operand support #39
Comments
|
There were some masks added in an earlier PoO that were missed when I was catching up on the instructions. Not sure how that happened. I have a couple others reported by one of the other developers to me personally. It looks like I need to do a full review of the vector instructions and see which ones are missing the mask. I will get to them when I can. A lot of life issues right now. Time consuming but not serious. |

No rush.

Thanks for letting me know.

I don't know if this occurs on all affected vector instructions or not, but it occurs on the
