Enum Class IntSDivOpGen

java.lang.Object
java.lang.Enum<IntSDivOpGen>
ghidra.pcode.emu.jit.gen.op.IntSDivOpGen
All Implemented Interfaces:
BinOpGen<JitIntSDivOp>, OpGen<JitIntSDivOp>, Serializable, Comparable<IntSDivOpGen>, Constable, org.objectweb.asm.Opcodes
public enum IntSDivOpGen extends Enum<IntSDivOpGen> implements BinOpGen<JitIntSDivOp>
The generator for a int_sdiv.

This uses the binary operator generator and simply emits Opcodes.IDIV or Opcodes.LDIV depending on the type.

    • afterLeft

      public JitType afterLeft(JitCodeGenerator gen, JitIntSDivOp op, JitType lType, JitType rType, org.objectweb.asm.MethodVisitor rv)
      Description copied from interface: BinOpGen
      Emit code between reading the left and right operands

      This is invoked immediately after emitting code to push the left operand onto the stack, giving the implementation an opportunity to perform any manipulations of that operand necessary to set up the operation, before code to push the right operand is emitted.

      Specified by:
      afterLeft in interface BinOpGen<JitIntSDivOp>
      Parameters:
      gen - the code generator
      op - the operator
      lType - the actual type of the left operand
      rType - the actual type of the right operand
      rv - the method visitor
      Returns:
      the new actual type of the left operand

    • generateBinOpRunCode

      public JitType generateBinOpRunCode(JitCodeGenerator gen, JitIntSDivOp op, JitControlFlowModel.JitBlock block, JitType lType, JitType rType, org.objectweb.asm.MethodVisitor rv)
      Description copied from interface: BinOpGen
      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.

      Specified by:
      generateBinOpRunCode in interface BinOpGen<JitIntSDivOp>
      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
