◆ applySignatureConversion()

Block * ConversionPatternRewriterImpl::applySignatureConversion	(	Block *	block,
		const TypeConverter *	converter,
		TypeConverter::SignatureConversion &	signatureConversion
	)

Apply the given signature conversion on the given block.

The new block containing the updated signature is returned. If no conversions were necessary, e.g. if the block has no arguments, block is returned. converter is used to generate any necessary cast operations that translate between the origin argument types and those specified in the signature conversion.

◆ buildUnresolvedMaterialization()

		ValueVector	valuesToMap,
		ValueRange	inputs,
		TypeRange	outputTypes,
		Type	originalType,
		const TypeConverter *	converter,
		bool	isPureTypeConversion = `true`
	)

Build an unresolved materialization operation given a range of output types and a list of input operands.

Build an unresolved materialization operation given an output type and set of input operands.

Returns the inputs if they their types match the output types.

If a cast op was built, it can optionally be returned with the castOp output argument.

If valuesToMap is set to a non-null Value, then that value is mapped to the results of the unresolved materialization in the conversion value mapping.

If isPureTypeConversion is "true", the materialization is created only to resolve a type mismatch. That means it is not a regular value replacement issued by the user. (Replacement values that are created "out of thin air" appear like unresolved materializations because they are unrealized_conversion_cast ops. However, they must be treated like regular value replacements.)
