Member Function Documentation

◆ applySignatureConversion()

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

Apply a signature conversion to the entry block of the given region.

This replaces the entry block with a new block containing the updated signature. The new entry block to the region is returned for convenience.

If provided, converter will be used for any materializations.

Definition at line 1506 of file DialectConversion.cpp.

◆ cancelRootUpdate()

void ConversionPatternRewriter::cancelRootUpdate ( Operation * op )

overridevirtual

PatternRewriter hook for updating the root operation in-place.

Reimplemented from mlir::RewriterBase.

Definition at line 1633 of file DialectConversion.cpp.

◆ 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 691 of file DialectConversion.h.

◆ cloneRegionBefore()

void ConversionPatternRewriter::cloneRegionBefore	(	Region &	region,
		Region &	parent,
		Region::iterator	before,
		IRMapping &	mapping
	)

overridevirtual

PatternRewriter hook for cloning blocks of one region into another.

The given region to clone must not have been modified as part of conversion yet, i.e. it must be within an operation that is either in the process of conversion, or has not yet been converted.

Reimplemented from mlir::RewriterBase.

Definition at line 1591 of file DialectConversion.cpp.

References mlir::RewriterBase::cloneRegionBefore(), mlir::Region::empty(), mlir::IRMapping::lookup(), mlir::PreOrder, and mlir::Block::walk().

◆ convertNonEntryRegionTypes()

LogicalResult ConversionPatternRewriter::convertNonEntryRegionTypes	(	Region *	region,
		const TypeConverter &	converter,
		ArrayRef< TypeConverter::SignatureConversion >	blockConversions
	)

Convert the types of block arguments within the given region except for the entry region.

This replaces each non-entry block with a new block containing the updated signature.

If special conversion behavior is needed for the non-entry blocks (for example, we need to convert only a subset of a BB arguments), such behavior can be specified in blockConversions.

Definition at line 1518 of file DialectConversion.cpp.

◆ convertRegionTypes()

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

Convert the types of block arguments within the given region.

This replaces each block with a new block containing the updated signature. The entry block may have a special conversion if entryConversion is provided. On success, the new entry block to the region is returned for convenience. Otherwise, failure is returned.

overridevirtual

PatternRewriter hook for erase all operations in a block.

PatternRewriter hook for erasing a dead operation.
