Class FunctionOptype

java.lang.Object
com.pnfsoftware.jeb.core.units.code.asm.decompiler.ir.FunctionOptype
@Ser public class FunctionOptype extends Object
Custom operator ("function") used to build custom operations.

  • Field Details

    • FLAG_OPND_HAVE_SAME_BITSIZE

      public static final int FLAG_OPND_HAVE_SAME_BITSIZE
      This flag indicates that all operands should have the same bitsize. This check is enforced when creating operations using such a function type.
      See Also:

    • FLAG_PASSTHRU_FOR_ECALL_DFA_CALCULATION

      public static final int FLAG_PASSTHRU_FOR_ECALL_DFA_CALCULATION
      This flag is reserved for single-operand custom operators to specify that the operand is to be treated as a pointer, and the data pointed by it should be treated as such during data-flow calculations.

      This is especially important for DFA calculations of IECall. Essentially, code like: 

       call(1, 2, 3, CUSTOM_FUNC(par_stkvarX))
      will be treated the same as the following by IECall.getDefUse(): 
       call(1, 2, 3, par_stkvarX)
