WebFeb 27, 1997 · Simpson identified another approach to GVN, called Strongly Connected Component (SCC)-Based Value Numbering [45, 46], which uses a hashtable but is flexible enough to allow for congruence classes ... WebOct 23, 2024 · There are two main approaches to global value numbering, as described in ["Value Numbering"][], Briggs, Cooper, and Simpson, 1997, both of which ultimately require input code in SSA form. Hash-based techniques, like those used in local value numbering, hash operations and find redundant values by comparing to previously hashed operations.

Standardization of the attribute values involves a z-transform, where the mean for all values is subtracted from each …
WebJun 1, 1997 · Value numbering is a compiler‐based program analysis method that allows redundant computations to be removed. This paper compares hash‐based approaches derived from the classic local algorithm1 with partitioning approaches based on the work of Alpern, Wegman and Zadeck.2 Historically, the hash‐based algorithm has been applied to … Weba particular relevant life policy are subject to SCC rules.
