Detailed Description

Include the generated interface declarations.

The pass expands memref operations that modify the metadata of a memref (sizes, offset, strides) into a sequence of easier to analyze constructs.

Implementation of a pass that rewrites the IR so that uses of gpu::AddressSpaceAttr in memref memory space annotations are replaced with caller-specified numeric values.

In particular, this pass transforms operations into explicit sequence of operations that model the effect of this operation on the different metadata. This pass uses affine constructs to materialize these effects.

FilterFunctionType

using mlir::FilterFunctionType = typedef std::function<bool(Operation &)>

A NestedPattern is a nested operation walker that:

1. recursively matches a substructure in the tree;
2. uses a filter function to refine matches with extra semantic constraints (passed via a lambda of type FilterFunctionType);
3. TODO: optionally applies actions (lambda).

Nested patterns are meant to capture imperfectly nested loops while matching properties over the whole loop nest. For instance, in vectorization we are interested in capturing all the imperfectly nested loops of a certain type and such that all the load and stores have certain access patterns along the loops' induction variables). Such NestedMatches are first captured using the match function and are later processed to analyze properties and apply transformations in a non-greedy way.

The NestedMatches captured in the IR can grow large, especially after aggressive unrolling. As experience has shown, it is generally better to use a plain walk over operations to match flat patterns but the current implementation is competitive nonetheless.

• Moves (i.e. doesnt clone) operations from the loop to the newly created loop
• Replaces the uses of loop with the new loop.
• loop isnt erased, but is left in a "no-op" state where the body of the loop just yields the basic block arguments that correspond to the initialization values of a loop. The loop is dead after this method.

SparseParallelizationStrategy

Defines a parallelization strategy.

Any independent loop is a candidate for parallelization. The loop is made parallel if (1) allowed by the strategy (e.g., AnyStorageOuterLoop considers either a dense or sparse outermost loop only), and (2) the generated code is an actual for-loop (and not a co-iterating while-loop).

SparseToSparseConversionStrategy

enum mlir::SparseToSparseConversionStrategy

strong

Defines a strategy for implementing sparse-to-sparse conversion.

kAuto leaves it up to the compiler to automatically determine the method used. kViaCOO converts the source tensor to COO and then converts the COO to the target format. kDirect converts directly via the algorithm in https://arxiv.org/abs/2001.02609; however, beware that there are many formats not supported by this conversion method.

The presence of the kAuto option violates our usual goal of keeping policy completely separated from mechanism. The reason it exists is because (at present) this strategy can only be specified on a per-file basis. To see why this is a problem, note that kDirect cannot support certain conversions; so if there is no kAuto setting, then whenever a file contains a single non-kDirect-able conversion the user would be forced to use kViaCOO for all conversions in that file! In the future, instead of using this enum as a Pass option, we could instead move it to being an attribute on the conversion op; at which point kAuto would no longer be necessary.

		Block::iterator	end,
		const AffineCopyOptions &	copyOptions,
		std::optional< Value >	filterMemRef,
		DenseSet< Operation * > &	copyNests
	)

Performs explicit copying for the contiguous sequence of operations in the block iterator range [‘begin’, ‘end’), where ‘end’ can't be past the terminator of the block (since additional operations are potentially inserted right before end.

copyOptions provides various parameters, and the output argument copyNests is the set of all copy nests inserted, each represented by its root affine.for. Since we generate alloc's and dealloc's for all fast buffers (before and after the range of operations resp. or at a hoisted position), all of the fast memory capacity is assumed to be available for processing this block range. When 'filterMemRef' is specified, copies are only generated for the provided MemRef. Returns success if the explicit copying succeeded for all memrefs on which affine load/stores were encountered.

AffineMap mlir::alignAffineMapWithValues	(	AffineMap	map,
		ValueRange	operands,
		ValueRange	dims,
		ValueRange	syms,
		SmallVector< Value > *	newSyms = nullptr
	)

Re-indexes the dimensions and symbols of an affine map with given operands values to align with dims and syms values.

Each dimension/symbol of the map, bound to an operand o, is replaced with dimension i, where i is the position of o within dims. If o is not in dims, replace it with symbol i, where i is the position of o within syms. If o is not in syms either, replace it with a new symbol.

Note: If a value appears multiple times as a dimension/symbol (or both), all corresponding dim/sym expressions are replaced with the first dimension bound to that value (or first symbol if no such dimension exists).

The resulting affine map has dims.size() many dimensions and at least syms.size() many symbols.

The SSA values of the symbols of the resulting map are optionally returned via newSyms. This is a concatenation of syms with the SSA values of the newly added symbols.

Note: As part of this re-indexing, dimensions may turn into symbols, or vice versa.

applyOpPatternsAndFold() [1/2]

LogicalResult mlir::applyOpPatternsAndFold	(	ArrayRef< Operation * >	ops,
		const FrozenRewritePatternSet &	patterns,
		GreedyRewriteStrictness	strictMode,
		bool *	changed = nullptr,
		bool *	allErased = nullptr,
		Region *	scope = nullptr
	)

Applies the specified rewrite patterns on ops while also trying to fold these ops.

Newly created ops and other pre-existing ops that use results of rewritten ops or supply operands to such ops are simplified, unless such ops are excluded via strictMode. Any other ops remain unmodified (i.e., regardless of strictMode).

• GreedyRewriteStrictness::AnyOp: No ops are excluded.
• GreedyRewriteStrictness::ExistingAndNewOps: Only pre-existing and newly created ops are simplified. All other ops are excluded.
• GreedyRewriteStrictness::ExistingOps: Only pre-existing ops are simplified. All other ops are excluded.

In addition to strictness, a region scope can be specified. Only ops within the scope are simplified. This is similar to applyPatternsAndFoldGreedily, where only ops within the given regions are simplified. If no scope is specified, it is assumed to be the first common enclosin
