Detailed Description

Specialization of PatternRewriter that OneToNConversionPatterns use.

The class provides additional rewrite methods that are specific to 1:N type conversions.

Member Function Documentation

◆ applySignatureConversion()

Block * OneToNPatternRewriter::applySignatureConversion	(	Block *	block,
		OneToNTypeMapping &	argumentConversion
	)

Applies the given argument conversion to the given block.

This consists of replacing each original argument with N arguments as specified in the argument conversion and inserting unrealized casts from the converted values to the original types, which are then used in lieu of the original ones. (Eventually, applyPartialOneToNConversion replaces these casts with a user-provided argument materialization if necessary.) This is similar to ArgConverter::applySignatureConversion but (1) handles 1:N type conversion properly and probably (2) doesn't handle many other edge cases.

◆ replaceOp()

void OneToNPatternRewriter::replaceOp	(	Operation *	op,
		ValueRange	newValues,
		const OneToNTypeMapping &	resultMapping
	)

Replaces the results of the operation with the specified list of values mapped back to the original types as specified in the provided type mapping.

That type mapping must match the replaced op (i.e., the original types must be the same as the result types of the op) and the new values (i.e., the converted types must be the same as the types of the new values).
