I'm fine with that if that is what we want. So something like the following?
+;; This option existed in the past, but now is always silently ignored.
mdirect-move
-Target Undocumented Mask(DIRECT_MOVE) Var(rs6000_isa_flags) WarnRemoved
+Target Undocumented Ignore
The above seems to silently ignore both -mdirect-move and -mno-direct-move
which I think is what we want. That said, it's not what we've done with
other options, but maybe those just need to be changed too?
