Examples with Insn3rc soot.toDex.instructions.Insn3rc used on opensource projects

Example 1 with Insn3rc

use of soot.toDex.instructions.Insn3rc in project soot by Sable.

the class ExprVisitor method buildInvokeInsn.

private Insn buildInvokeInsn(String invokeOpcode, MethodReference method, List<Register> argumentRegs) {
    Insn invokeInsn;
    int regCountForArguments = SootToDexUtils.getRealRegCount(argumentRegs);
    if (regCountForArguments <= 5) {
        Register[] paddedArray = pad35cRegs(argumentRegs);
        Opcode opc = Opcode.valueOf(invokeOpcode);
        invokeInsn = new Insn35c(opc, regCountForArguments, paddedArray[0], paddedArray[1], paddedArray[2], paddedArray[3], paddedArray[4], method);
    } else if (regCountForArguments <= 255) {
        Opcode opc = Opcode.valueOf(invokeOpcode + "_RANGE");
        invokeInsn = new Insn3rc(opc, argumentRegs, (short) regCountForArguments, method);
    } else {
        throw new Error("too many parameter registers for invoke-* (> 255): " + regCountForArguments + " or registers too big (> 4 bits)");
    }
    // save the return type for the move-result insn
    stmtV.setLastReturnTypeDescriptor(method.getReturnType());

Example 2 with Insn3rc

use of soot.toDex.instructions.Insn3rc in project soot by Sable.

the class ExprVisitor method caseNewMultiArrayExpr.

@Override

    } else {
        stmtV.addInsn(new Insn3rc(Opcode.FILLED_NEW_ARRAY_RANGE, dimensionSizeRegs, dimensions, arrayTypeItem), null);
    }
    // check for > 255 is done already
    // move the resulting array into the destination register
    stmtV.addInsn(new Insn11x(Opcode.MOVE_RESULT_OBJECT, destinationReg), origStmt);
