OpenACCExecMapping

enum mlir::acc::OpenACCExecMapping

Enumeration used to encode the execution mapping on a loop construct.

They refer directly to the OpenACC 3.3 standard: 2.9.2. gang 2.9.3. worker 2.9.4. vector

Value can be combined bitwise to reflect the mapping applied to the construct. e.g. acc.loop gang vector, the gang and vector could be combined and the final mapping value would be 5 (4 | 1).

buildComputeRegion()

ComputeRegionOp mlir::acc::buildComputeRegion	(	Location	loc,
		ValueRange	launchArgs,
		ValueRange	inputArgs,
		llvm::StringRef	origin,
		Region &	regionToClone,
		RewriterBase &	rewriter,
		IRMapping &	mapping,
		ValueRange	output = {},
		FlatSymbolRefAttr	kernelFuncName = {},
		FlatSymbolRefAttr	kernelModuleName = {},
		Value	stream = {},
		ValueRange	inputArgsToMap = {} )

Build an acc.compute_region operation by cloning a source region.

Creates a new acc.compute_region with the given launch arguments and origin string, then clones the operations from regionToClone into its body. Launch operands should be acc.par_width results (index); the region entry block gets matching index block arguments first, then arguments for each ins operand. Multi-block regions are wrapped with scf.execute_region.

The mapping is used and updated during cloning, allowing callers to track value correspondences. Optional output, kernelFuncName, kernelModuleName, and stream arguments are forwarded to the op.

When inputArgsToMap is non-empty, it is used as the key set for the clone mapping (instead of inputArgs). Use this when cloning a region that references one set of values (e.g. the source function's args) while the op's operands are another set (e.g. the current block's args). inputArgsToMap must have the same size as inputArgs when provided.

Clone an ACC region into a destination block at the given insertion point.

Requires a single-block source region. Maps block arguments and optional result replacement: values in resultsToReplace are replaced with the leading operands of the cloned region's acc.yield (1:1). Erases acc.yield/terminator and merges blocks. Returns all yielded values, including any values not used as replacements, and the insertion point after the clone.

The messageFn is only invoked if remarks are enabled, allowing callers to avoid constructing expensive messages when remarks are disabled.

Parameters

op	The operation to emit the remark for.
messageFn	A callable that returns the remark message.
category	Optional category for the remark. Defaults to "openacc".

Returns

An in-flight remark object that can be used to append additional information to the remark.

Both have to produce a value, and of the same type. With no condition only thenFn is emitted and its value returned. As with emitGuardedByIfCond, the insertion point is left after the branch.

		ModuleOp	module,
		const DataLayout &	dl,
		OpenACCSupport *	support = nullptr,
		Value	var = {} )

Returns the size and ABI alignment in bytes.

For aggregate structures and arrays, padding between members or elements is not taken into account. The result is a close estimate suitable for early OpenACC layout decisions, but not a complete ABI guarantee. For final size computations, use LLVM materialized types.

ty itself is sized dialect-agnostically; when support is provided it sizes aggregate element types, so that nested dialect types are handled. Callers that hold an OpenACCSupport should therefore ask it directly - OpenACCSupport::getTypeSizeAndAlignment covers dialect types and falls back to this utility - and call this utility directly only for a type this utility is expected to know.

When var is provided, MappableType sizes the mapped object rather than the type's storage alone.

Returns std::nullopt when the size is not statically computable or the type is not supported.

True when another data clause of the same construct maps the same variable with a copy-back and no copy-in.

One entry operation is emitted per clause, so a construct such as create(a) copyout(a) or copyin(a) copyout(a) maps a twice. The runtime keeps one mapping per variable and acts on it once, which makes the copy-back depend on whichever entry it processes: the entry that has no copy-back of its own must therefore carry from as well.

spliceConstructRegion()

void mlir::acc::spliceConstructRegion	(	Operation *	op,

Splices region, the body of a structured construct, into the block holding op, so that the construct itself can be erased.

The code that follows op is branched to where the region ends, whether it ends in an acc.terminator or, as a region holding no terminator does, at the end of its blocks.

tileACCLoops()

mlir::acc::LoopOp mlir::acc::tileACCLoops	(	mlir::acc::LoopOp	tileLoop,
		const llvm::SmallVector< mlir::Value > &	tileSizes,
		int32_t	defaultTileSize,
		mlir::RewriterBase &	rewriter )

Tile a single fused acc.loop that carries all associated induction variables (one IV per tile dimension).

This produces exactly two multi-IV loops, each carrying all of the tiled induction variables:

• a "tile group" loop that steps over tiles: each step is the original step multiplied by the tile size. It keeps the original loop's gang attribute.
• an "element group" loop that walks the iterations inside one tile: it keeps the original step, its lower bound is the current tile's starting index, and its upper bound is clamped to min(original upper bound, tile start + tile extent). It keeps the original loop's vector (or worker) attribute.

Before Tiling:

#pragma acc loop tile(tile_size1, tile_size2)
 for (i = lb1; i < ub1; i += step1) { // original loop
   for (j = lb2; j < ub2; j += step2) {
     a[i,j] = i + j;
   }
 }

After Tiling (each group is one multi-IV loop over all tiled IVs):

// tile group
for (i = lb1; i < ub1; i += (step1 * tile_size1),
     j = lb2; j < ub2; j += (step2 * tile_size2)) {
  // element group
  for (ii = i; ii < min(ub1, (step1 * tile_size1) + i); ii += step1,
       jj = j; jj < min(ub2, (step2 * tile_size2) + j); jj += step2) {
    a[ii,jj] = i + j;
  }
}

Unknown tile sizes (represented as -1 in acc dialect for tile(*)) are resolved to the provided default tile size.

Parameters

tileLoop	The fused loop to tile.
tileSizes	The tile sizes for each tiled dimension. Values of -1 are treated as unknown and resolved to defaultTileSize.
defaultTileSize	The default tile size to use for unknown (*) tiles.
rewriter	The rewriter to use for modifications.

Returns

The tile group loop that is modified in place.

scf::ExecuteRegionOp mlir::acc::wrapMultiBlockRegionWithSCFExecuteRegion	(	Region &	region,
		IRMapping &	mapping,
		Location	loc,
		RewriterBase &	rewriter )

Wrap a multi-block region in an scf.execute_region.

Wrap a multi-block region with scf.execute_region.

Clones the given region into a new scf.execute_region. Terminators with no successors (i.e., region exit points) are replaced with scf.yield. Use this to convert unstructured control flow (e.g. multiple blocks with branches) into a single SCF region.

Parameters

region	The region to wrap (cloned into the execute_region; not modified).
mapping	IR mapping for the clone; updated with block and value mappings.
loc	Location for the created execute_region op.
rewriter	RewriterBase for creating and erasing operations.

Returns

The created scf.execute_region operation.
