Detailed Description
Cleanup: Convert truncation to cast: sub(V,c) => sub(V>>c*8,0)
If the lone descendant of the SUBPIECE is a INT_RIGHT or INT_SRIGHT, we lump that into the shift as well.
Member Function Documentation
Attempt to apply this Rule.
This method contains the main logic for applying the Rule. It must use a given PcodeOp as the point at which the Rule applies. If it does apply, changes are made directly to the function and 1 (non-zero) is returned, otherwise 0 is returned.
Reimplemented from Rule.

Clone the Rule.
If this Rule is a member of one of the groups in the grouplist, this returns a clone of the Rule, otherwise NULL is returned.
- Parameters
-
grouplist is the list of groups being cloned
- Returns
- the cloned Rule or NULL
Implements Rule.
