Class InstructionPcodeOverride

java.lang.Object
ghidra.program.model.listing.InstructionPcodeOverride
All Implemented Interfaces:
PcodeOverride
public class InstructionPcodeOverride extends Object implements PcodeOverride

  • Field Details

  • Constructor Details

    • InstructionPcodeOverride

      public InstructionPcodeOverride(Instruction instr)
      This constructor caches the primary and overriding "from" references of instr. This cache is never updated; the assumption is that this object is short-lived (duration of PcodeEmit)
      Parameters:
      instr - the instruction

    • hasCallFixup

      public boolean hasCallFixup(Address callDestAddr)
      Description copied from interface: PcodeOverride
      Returns the call-fixup for a specified call destination.
      Specified by:
      hasCallFixup in interface PcodeOverride
      Parameters:
      callDestAddr - call destination address. This address is used to identify a function which may have been tagged with a CallFixup.
      Returns:
      true if call destination function has been tagged with a call-fixup

    • getCallFixup

      public InjectPayload getCallFixup(Address callDestAddr)

      Returns the call-fixup for a specified call destination. If the destination function has not be tagged or was tagged with an unknown CallFixup name this method will return null.
      Specified by:
      getCallFixup in interface PcodeOverride
      Parameters:
      callDestAddr - call destination address. This address is used to identify a function which may have been tagged with a CallFixup.
