struct FixedScalableVFPair

Declaration

struct FixedScalableVFPair { /* full declaration omitted */ };

Description

A class that represents two vectorization factors (initialized with 0 by default). One for fixed-width vectorization and one for scalable vectorization. This can be used by the vectorizer to choose from a range of fixed and/or scalable VFs in order to find the most cost-effective VF to vectorize with.
