Detailed Description
A variant of Store for +=, -=, *=, etc
Example: var_[indices_] += expr_
These operations follow commutative law. Making them the special ReduceTo nodes helps analyzing dependences more accurately
Member Function Documentation

Implements freetensor::ASTPart.
Member Data Documentation
◆ expr_
◆ indices_
| SubTreeList<ExprNode> freetensor::ReduceToNode::indices_ = ChildOf{this} |
◆ op_
| ReduceOp freetensor::ReduceToNode::op_ |
◆ sync_
| bool freetensor::ReduceToNode::sync_ |
If true, can safely reduce from multiple threads to one location. Prefer atomic over other synchronizations
NOTE: Synchronizations only have to be done among ReduceTo nodes. No need to synchronize between a ReduceTo and a Load, or a ReduceTo and a Store, since our schedules prohibits simultaneous ReduceTo and Load, or ReduceTo and Store.
◆ var_
| std::string freetensor::ReduceToNode::var_ |
