Abstract
In one particular example, this disclosure provides an efficient mechanism to determine the degree of parallelization possible for a loop in the presence of possible memory aliases that cannot be resolved at compile-time. Hardware instructions are provided that test memory addresses at run-time and set a mode or register that enables a single instance of a loop to run the maximum number of SIMD (Single Instruction, Multiple Data) lanes to run in parallel that obey the semantics of the original scalar loop. Other hardware features that extend applicability or performance of such instructions are enumerated.
