Description Dmitry Selyutin 2022-05-17 10:40:28 BST 
Currently there's no agreement on bitmanip instructions. Once there's a consensus on these, they must also be added to binutils.

What's the state of this? IIRC there was a discussion about grev## instructions. Any consensus reached?

grev/grevw (etc) are going. grevlut and grevluti *are* replacing them.
they need implementing, bug #852.

Hi folks, what's the current state? It seems this should've been handled on openpower-isa side by Toshaan; any updates on this?
