SmallVector< Loops, 8 > mlir::tile (ArrayRef< scf::ForOp > forOps, ArrayRef< Value > sizes, ArrayRef< scf::ForOp > targets)
 Performs tiling fo imperfectly nested loops (with interchange) by strip-mining the forOps by sizes and sinking them, in their order of occurrence in forOps, under each of the targets. More...
Loops mlir::tile (ArrayRef< scf::ForOp > forOps, ArrayRef< Value > sizes, scf::ForOp target)
 Performs tiling (with interchange) by strip-mining the forOps by sizes and sinking them, in their order of occurrence in forOps, under target. More...
Loops mlir::tilePerfectlyNested (scf::ForOp rootForOp, ArrayRef< Value > sizes)
 Tile a nest of scf::ForOp loops rooted at rootForOp with the given (parametric) sizes. More...
void mlir::getPerfectlyNestedLoops (SmallVectorImpl< scf::ForOp > &nestedLoops, scf::ForOp root)
