Abstract: A vector friendly instruction format and execution thereof. According to one embodiment of the invention, a processor is configured to execute an instruction set. The instruction set includes a vector friendly instruction format. The vector friendly instruction format has a plurality of fields including a base operation field, a modifier field, an augmentation operation field, and a data element width field, wherein the first instruction format supports different versions of base operations and different augmentation operations through placement of different values in the base operation field, the modifier field, the alpha field, the beta field, and the data element width field, and wherein only one of the different values may be placed in each of the base operation field, the modifier field, the alpha field, the beta field, and the data element width field on each occurrence of an instruction in the first instruction format in instruction streams.

Abstract: Methods, apparatus, systems and articles of manufacture (e.g., computer readable storage media) to perform automatic compiler optimization to enable streaming-store generation for unaligned contiguous write access are disclosed. Example apparatus disclosed herein are to mark a store instruction in source program code as a transformation candidate when the store instruction is associated with a group of memory accesses that are unaligned with respect to a size of a cache line in a cache. Disclosed apparatus are also to transform the store instruction that is marked as the transformation candidate to form transformed program code when a non-temporal property is satisfied, the transformed program code to replace the store instruction with (i) a write to a buffer in the cache and (ii) a streaming-store instruction that is to write contents of the buffer to memory.
