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()

int4 RuleStoreVarnode::applyOp ( PcodeOp op,
Funcdata data 
)
virtual

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.

Parameters
opis the given PcodeOp where the Rule may apply
datais the function to which to apply

Reimplemented from Rule.

◆ clone()

virtual Rule* RuleStoreVarnode::clone ( const ActionGroupList grouplist) const
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
grouplistis the list of groups being cloned
Returns
the cloned Rule or NULL

Implements Rule.

◆ getOpList()

void RuleStoreVarnode::getOpList ( vector< uint4 > &  oplist) const
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
oplistis the array to populate

Reimplemented from Rule.
