1. A system for processing partially vectorized code, said system comprising: a partial vectorizing compiler to: determine hot paths and cold paths within a loop body; remove any determined cold paths from consideration for vectorization; identify backward dependencies within a plurality of iterations within the loop body of said code, wherein at least one of said plurality of iterations includes at least one backward dependency, wherein said identifying includes: generating a static single assignment (SSA) analysis of said loop body; generating a loop dependence graph (LDG) based on said SSA of said loop body, said LDG comprising nodes and edges, wherein said nodes are associated with vectorization units of said SSA and said edges are associated with dependence relations between said nodes, and wherein said vectorization units comprise statements, expressions and operations, and said dependence relations comprise control dependence edges (CDE) and data dependence edges (DDE); partitioning said LDG into one or more first-type regions and one or more second-type regions, wherein said first-type regions comprise backward dependency loops and said second-type regions do not comprise backward dependency loops; and classifying at least one first-type region into a first category including loops having induction variables, a second category including strictly sequential backward dependency loops or a third category including conditionally vectorized backward dependency loops; select one or more ranges of said plurality of iterations within said loop body, wherein said selected ranges exclude said identified backward dependencies, and vectorize said selected ranges; and a vector processor to execute said selected ranges, wherein said vector processor is a hardware processor including one or more scalar processors.
