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 1731 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 796 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.

◆ eraseBlock()

void ConversionPatternRewriter::eraseBlock ( Block block)
overridevirtual

PatternRewriter hook for erase all operations in a block.

This is not yet implemented for dialect conversion.

◆ finalizeOpModification()

void ConversionPatternRewriter::finalizeOpModification ( Operation op)
overridevirtual

PatternRewriter hook for updating the given operation in-place.

Reimplemented from mlir::RewriterBase.

Definition at line 1719 of file DialectConversion.cpp.

◆ getImpl()

detail::ConversionPatternRewriterImpl & ConversionPatternRewriter::getImpl ( )

Return a reference to the internal implementation.

Definition at line 1748 of file DialectConversion.cpp.

Referenced by mlir::OperationConverter::convertOperations().

◆ 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 1648 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,

ValueRange  argValues = std::nullopt 
)
overridevirtual

◆ 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 1559 of file DialectConversion.cpp.

References mlir::Operation::getResults().

◆ replaceOp() [2/2]

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

◆ 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.)

◆ replaceUsesOfBlockArgument()

void ConversionPatternRewriter::replaceUsesOfBlockArgument ( BlockArgument  from,
Value  to 
)

Replace all the uses of the block argument from with value to.

◆ 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.

Reimplemented from mlir::RewriterBase.
