I tried winding back to r197465 and it looks like you added these because
on z196 you got:
ogrk %r2, %r2, %r3 instead of ogr %r2, %r3
and ork %r2, %r2, %r3 instead of or %r2, %r3
Is that right? We don't really want to use the three-address forms
(OGRK and ORK) when the two-address form would do. In these cases
I think the destination and first source are natural ties so we really
should be using OGR and OR for z196 too.
It looks like current trunk (r197599) works again for -mcpu=z196.
Would it be OK to revert this for now?
