Method using SLP packing with statements having both isomorphic and non-isomorphic expressions

摘要

Disclosure for using SLP in processing a plurality of statements, wherein the statements are associated with an array having a number of array positions, and each statement includes one or more expressions. Expressions are gathered for each of the statements into a structure comprising a single merge stream furnished with a location for each expression. The location for a given expression is associated with one of the array positions. A plurality of expressions are selectively identified and SLP packing operations are applied to the identified expressions to merge into one or more isomorphic sub-streams. Expressions of the isomorphic sub-streams and other expressions of the single merge stream are combined into a number of input vectors that are substantially equal in length to one another. A location vector is generated that contains the respective locations for all of the expressions in the single merge stream.
