I'll repeat a comment sent personally to you before.

>I tried an implementation in a similar way to AccReductionOperator::Operator. It cannot tell the reason for parsing failures. The name of AccReductionOperator::Operator is redundant. I tried to add ReduceOperation::Add directly (without ::Operator::), but the OpenACC version has a sourced parser. Defining 'source' in 'ReduceOperation' does not match with other code.

There was no CUF REDUCE support that time. Should I check it?
