Class InstructionPcodeOverride

  • All Implemented Interfaces:
    PcodeOverride
    public class InstructionPcodeOverride
extends java.lang.Object
implements PcodeOverride

    • Constructor Detail

      • 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
