Public Attributes
SmallVector< Instruction * >	Instrs
	The insertelement instructions that form the pack pattern in bottom-up order, i.e., the first instruction in Instrs is the bottom-most InsertElement instruction of the pack pattern.
SmallVector< Value * >	Operands
	The "external" operands of the pack pattern, i.e., the values that get packed into a vector, skipping the ones in Instrs.

Detailed Description

Member Data Documentation

Instrs

SmallVector<Instruction *> llvm::sandboxir::VecUtils::PackPattern::Instrs

The insertelement instructions that form the pack pattern in bottom-up order, i.e., the first instruction in Instrs is the bottom-most InsertElement instruction of the pack pattern.

For example in this simple pack pattern: Pack0 = insertelement <2 x i8> poison, i8 v0, i64 0 Pack1 = insertelement <2 x i8> Pack0, i8 v1, i64 1 this is [ Pack1, Pack0 ].

Operands

SmallVector<Value *> llvm::sandboxir::VecUtils::PackPattern::Operands

The "external" operands of the pack pattern, i.e., the values that get packed into a vector, skipping the ones in Instrs.

The operands are in bottom-up order, starting from the operands of the bottom-most insert. So in our example this would be [ v1, v0 ].
