 [[isa/fixedshift]].  bmext is actually covered already (shift-with-mask rldicl but only immediate version).
 however bitmask-invert is not, and set/clr are not covered, although they can use the same Shift ALU.
 
-bmext (RB) version is not the same as rldicl because bmext is a right shift by RC, where rldicl is a left rotate.  for the immediate version this does not matter.
+bmext (RB) version is not the same as rldicl because bmext is a right shift by RC, where rldicl is a left rotate.  for the immediate version this does not matter, so a bmexti is not required.
+bmrev however there is no direct equivalent and consequently a bmrevi is required.
