Detailed Description

template<typename LoopTy>
struct mlir::linalg::GenerateLoopNest< LoopTy >

Utility class used to generate nested loops with ranges described by loopRanges and loop type described by the iteratorTypes.

bodyBuilderFn is used to generate the body of the innermost loop. It is passed a range of loop induction variables and a range of operand values to use.
