    SmallVectorImpl<SCEV const*>& Sizes,
    SCEV const* ElementSize);

Parameters

Name

Description

Scalar evolution used to GCD‐divide the collected terms.

Terms

Parametric terms extracted from the access function.

Sizes

Filled with the inferred size of each array dimension.

ElementSize

Size in bytes of one array element.
