Hi Jochen,
I still have a quesiton: How can I load variables via Groovy
utilities? Here[1] is my current way to load varaibles, it is not correct
though it can compile and run(i.e. the related test can not pass[2]):
I tried the following way, but error occurred[3]...
```
int newRegister = 0;
Parameter[] lambdaSharedVariableParameters =
syntheticLambdaMethodNode.getNodeMetaData(LAMBDA_SHARED_VARIABLES);
for (Parameter parameter : lambdaSharedVariableParameters) {
ClassNode type = parameter.getType();
operandStack.load(parameter.getType(), newRegister);
// increment to next register, double/long are using two places
newRegister++;
if (type == ClassHelper.double_TYPE || type ==
ClassHelper.long_TYPE) newRegister++;
}
operandStack.remove(lambdaSharedVariableParameters.length);
```
Could you tell me how to load variables properly?
Cheers,
Daniel.Sun
