◆ registerConstraintFunction() [2/2]

void PDLPatternModule::registerConstraintFunction	(	StringRef	name,
		PDLConstraintFunction	constraintFn
	)

Register a constraint function with PDL.

A constraint function may be specified in one of two ways:

LogicalResult (PatternRewriter &, ArrayRef<PDLValue>)

In this overload the arguments of the constraint function are passed via the low-level PDLValue form.

LogicalResult (PatternRewriter &, ValueTs... values)

In this form the arguments of the constraint function are passed via the expected high level C++ type. In this form, the framework will automatically unwrap PDLValues and convert them to the expected ValueTs. For example, if the constraint function accepts a Operation *, the framework will automatically cast the input PDLValue. In the case of a StringRef, the framework will automatically unwrap the argument as a StringAttr and pass the underlying string value. To see the full list of supported types, or to see how to add handling for custom types, view the definition of ProcessPDLValue above.

◆ registerRewriteFunction() [1/2]

void PDLPatternModule::registerRewriteFunction	(	StringRef	name,
		PDLRewriteFunction	rewriteFn
	)

Register a rewrite function with PDL.

A rewrite function may be specified in one of two ways:

void (PatternRewriter &, PDLResultList &, ArrayRef<PDLValue>)

In this overload the arguments of the constraint function are passed via the low-level PDLValue form, and the results are manually appended to the given result list.

ResultT (PatternRewriter &, ValueTs... values)

In this form the arguments and result of the rewrite function are passed via the expected high level C++ type. In this form, the framework will automatically unwrap the PDLValues arguments and convert them to the expected ValueTs. It will also automatically handle the processing and packaging of the result value to the result list. For example, if the rewrite function takes a Operation *, the framework will automatically cast the input PDLValue. In the case of a StringRef, the framework will automatically unwrap the argument as a StringAttr and pass the underlying string value. In the reverse case, if the rewrite returns a StringRef or std::string, it will automatically package this as a StringAttr and append it to the result list. To see the full list of supported types, or to see how to add handling for custom types, view the definition of ProcessPDLValue above.
