Detailed Description

This class implements a pattern rewriter for use with ConversionPatterns.

It extends the base PatternRewriter and provides special conversion specific hooks.

Member Function Documentation

◆ applySignatureConversion()

Block * ConversionPatternRewriter::applySignatureConversion	(	Block *	block,
		TypeConverter::SignatureConversion &	conversion,
		const TypeConverter *	converter = `nullptr`
	)

Apply a signature conversion to given block.

This replaces the block with a new block containing the updated signature. The operations of the given block are inlined into the newly-created block, which is returned.

If no block argument types are changing, the original block will be left in place and returned.

A signature converison must be provided. (Type converters can construct a signature conversion with convertBlockSignature.)

Optionally, a type converter can be provided to build materializations. Note: If no type converter was provided or the type converter does not specify any suitable argument/target materialization rules, the dialect conversion may fail to legalize unresolved materializations.

◆ cancelOpModification()

void ConversionPatternRewriter::cancelOpModification ( Operation * op )

overridevirtual

PatternRewriter hook for updating the given operation in-place.

Reimplemented from mlir::RewriterBase.

Definition at line 1826 of file DialectConversion.cpp.

References rewrite().

◆ canRecoverFromRewriteFailure()

bool mlir::ConversionPatternRewriter::canRecoverFromRewriteFailure ( ) const

inlineoverridevirtual

Indicate that the conversion rewriter can recover from rewrite failure.

Recovery is supported via rollback, allowing for continued processing of patterns even if a failure is encountered during the rewrite step.

Reimplemented from mlir::PatternRewriter.

Definition at line 866 of file DialectConversion.h.

◆ convertRegionTypes()

FailureOr< Block * > ConversionPatternRewriter::convertRegionTypes	(	Region *	region,
		const TypeConverter &	converter,
		TypeConverter::SignatureConversion *	entryConversion = `nullptr`
	)

Apply a signature conversion to each block in the given region.

This replaces each block with a new block containing the updated signature. If an updated signature would match the current signature, the respective block is left in place as is. (See applySignatureConversion for details.) The new entry block of the region is returned.

SignatureConversions are computed with the specified type converter. This function returns "failure" if the type converter failed to compute a SignatureConversion for at least one block.

Optionally, a special SignatureConversion can be specified for the entry block. This is because the types of the entry block arguments are often tied semantically to the operation.

PatternRewriter hook for erasing a dead operation.

The uses of this operation must be made dead by the end of the conversion process, otherwise an assert will be issued.

◆ finalizeOpModification()

overridevirtual

PatternRewriter hook for updating the given operation in-place.

◆ getRemappedValue()

Value ConversionPatternRewriter::getRemappedValue ( Value key )

Return the converted value of 'key' with a type defined by the type converter of the currently executing pattern.

Return nullptr in the case of failure, the remapped value otherwise.

Definition at line 1735 of file DialectConversion.cpp.

◆ getRemappedValues()

LogicalResult ConversionPatternRewriter::getRemappedValues	(	ValueRange	keys,
		SmallVectorImpl< Value > &	results
	)

Return the converted values that replace 'keys' with types defined by the type converter of the currently executing pattern.

Returns failure if the remap failed, success otherwise.

void ConversionPatternRewriter::inlineBlockBefore	(	Block *	source,
		Block *	dest,
		Block::iterator	before,
		ValueRange	argValues = `std::nullopt`
	)

overridevirtual

PatternRewriter hook for inlining the ops of a block into another block.

◆ replaceOp() [1/2]

void ConversionPatternRewriter::replaceOp	(	Operation *	op,
		Operation *	newOp
	)

overridevirtual

Replace the given operation with the results of the new op.

The number of op results must match. The types may differ: the dialect conversion driver will reconcile any surviving type mismatches at the end of the conversion process with source materializations. The original operation is erased.

Reimplemented from mlir::RewriterBase.

Definition at line 1650 of file DialectConversion.cpp.

References mlir::Operation::getResults().

◆ replaceOp() [2/2]

void ConversionPatternRewriter::replaceOp	(	Operation *	op,
		ValueRange	newValues
	)

overridevirtual

Replace the given operation with the new values.

The number of op results and replacement values must match. The types may differ: the dialect conversion driver will reconcile any surviving type mismatches at the end of the conversion process with source materializations. The given operation is erased.

Reimplemented from mlir::RewriterBase.

Definition at line 1655 of file DialectConversion.cpp.

References mlir::Operation::getName(), and mlir::Operation::getNumResults().

◆ replaceOpWithMultiple()

void ConversionPatternRewriter::replaceOpWithMultiple	(	Operation *	op,
		ArrayRef< ValueRange >	newValues
	)

Replace the given operation with the new value ranges.

The number of op results and value ranges must match. If an original SSA value is replaced by multiple SSA values (i.e., a value range has more than 1 element), the conversion driver will insert an argument materialization to convert the N SSA values back into 1 SSA value of the original type. The given operation is erased.

Note: The argument materialization is a workaround until we have full 1:N support in the dialect conversion. (It is going to disappear from both replaceOpWithMultiple and applySignatureConversion.)

◆ startOpModification()

void ConversionPatternRewriter::startOpModification ( Operation * op )
