Detailed Description

template<typename ParDimAttrT>
class mlir::acc::ACCParMappingPolicy< ParDimAttrT >

Policy class that defines how OpenACC parallelism levels map to target-specific parallel dimension attributes.

Implementations provide the actual mapping.

Template parameter ParDimAttrT specifies the attribute type returned by the mapping functions (e.g., mlir::acc::GPUParallelDimAttr for GPU targets).

This policy allows different mapping strategies:

• Standard GPU mapping (gang->block, worker->threadY, vector->threadX)
• Custom mappings for specific targets or optimization strategies

Pass an implementation to functions that need to perform the mapping.
