Abstract: Loop vectorization methods and apparatus are disclosed. An example method includes setting a dynamic adjustment value of a vectorization loop; executing the vectorization loop to vectorize a loop by grouping iterations of the loop into one or more vectors; identifying a dependency between iterations of the loop as; and setting the dynamic adjustment value based on the identified dependency.
