Package ghidra.pcode.emu.jit.gen.op

Interface ShiftIntBinOpGen<T extends JitIntBinOp>

Type Parameters:
T - the class of p-code op node in the use-def graph
All Superinterfaces:
BinOpGen<T>, org.objectweb.asm.Opcodes, OpGen<T>
All Known Implementing Classes:
IntLeftOpGen, IntRightOpGen, IntSRightOpGen
public interface ShiftIntBinOpGen<T extends JitIntBinOp> extends BinOpGen<T>
An extension for integer shift operators

This is just going to invoke one of the JitCompiledPassage.intLeft(int, int), JitCompiledPassage.intRight(int, int), JitCompiledPassage.intSRight(int, int), etc. methods, depending on the operand types.

  • Method Details

    • methodName

      String methodName()
      The name of the static method in JitCompiledPassage to invoke
      Returns:
      the name

    • generateBinOpRunCode

      default JitType generateBinOpRunCode(JitCodeGenerator gen, T op, JitControlFlowModel.JitBlock block, JitType lType, JitType rType, org.objectweb.asm.MethodVisitor rv)
      Emit code for the binary operator

      At this point both operands are on the stack. After this returns, code to write the result from the stack into the destination operand will be emitted.

      This reduces the implementation to just the name of the method to invoke. This will select the JVM signature of the method based on the p-code operand types.

      Specified by:
      generateBinOpRunCode in interface BinOpGen<T extends JitIntBinOp>
      Parameters:
      gen - the code generator
      op - the operator
      block - the block containing the operator
      lType - the actual type of the left operand
      rType - the actual type of the right operand
      rv - the method visitor
      Returns:
      the actual type of the result
