Detailed Description
Convert STORE operations using a constant offset to COPY.
The pointer can either be a constant offset into the STORE's specified address space, or it can be a spacebase register plus an offset, in which case it points into the spacebase register's address space.
Member Function Documentation
◆ applyOp()
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 ghidra::Rule.

◆ clone()
|
inlinevirtual |
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 ghidra::Rule.

◆ getOpList()
|
virtual |
List of op codes this rule operates on.
Populate the given array with all possible OpCodes this Rule might apply to. By default, this method returns all possible OpCodes
- Parameters
-
oplist is the array to populate
