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

If provided, converter will be used for any materializations.

Definition at line 1678 of file DialectConversion.cpp.

References mlir::Region::getParentOp().

◆ cancelOpModification()

void ConversionPatternRewriter::cancelOpModification ( Operation op)
overridevirtual

PatternRewriter hook for updating the given operation in-place.

Reimplemented from mlir::RewriterBase.

Definition at line 1801 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 721 of file DialectConversion.h.

◆ 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 an updated signature would match the current signature, the respective block is left in place as is.

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 1696 of file DialectConversion.cpp.

References mlir::Region::getParentOp().

◆ 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. If an updated signature would match the current signature, the respective block is left in place as is.

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.

◆ eraseBlock()

void ConversionPatternRewriter::eraseBlock ( Block block)
overridevirtual

PatternRewriter hook for erase all operations in a block.

This is not yet implemented for dialect conversion.

Referenced by mlir::detail::ConversionPatternRewriterImpl::applySignatureConversion().

◆ eraseOp()

void ConversionPatternRewriter::eraseOp ( Operation op)
overridevirtual

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.

Reimplemented from mlir::RewriterBase.

void ConversionPatternRewriter::finalizeOpModification ( Operation op)
overridevirtual

PatternRewriter hook for updating the given operation in-place.

Reimplemented from mlir::RewriterBase.

Definition at line 1789 of file DialectConversion.cpp.

◆ getImpl()

detail::ConversionPatternRewriterImpl & ConversionPatternRewriter::getImpl ( )

Return a reference to the internal implementation.

Definition at line 1818 of file DialectConversion.cpp.

◆ 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 1718 of file DialectConversion.cpp.

References mlir::failed().

◆ 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.

◆ inlineBlockBefore()

void ConversionPatternRewriter::inlineBlockBefore ( Block source,

Block::iterator  before,
ValueRange  argValues = std::nullopt 
)
overridevirtual

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

Reimplemented from mlir::RewriterBase.

◆ replaceOp() [1/2]

◆ startOpModification()

void ConversionPatternRewriter::startOpModification ( Operation op)
overridevirtual

PatternRewriter hook for updating the given operation in-place.

Note: These methods only track updates to the given operation itself, and not nested regions. Updates to regions will still require notification through other more specific hooks above.
