Detailed Description

Class for performing a single transformation on a PcodeOp or Varnode.

A Rule, through its applyOp() method, is handed a specific PcodeOp as a potential point to apply. It determines if it can apply at that point, then makes any changes. Rules inform the system of what types of PcodeOps they can possibly apply to through the getOpList() method. A set of Rules are pooled together into a single Action via the ActionPool, which efficiently applies each Rule across a whole function. A Rule supports the same breakpoint properties as an Action. A Rule is allowed to keep state that is specific to a given function (Funcdata). The reset() method is invoked to purge this state for each new function to be transformed.

Member Function Documentation

◆ applyOp()

virtual int4 ghidra::Rule::applyOp ( PcodeOp op,
Funcdata data 
)
inlinevirtual

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
