    Abstract: Embodiments of computer-implemented methods, systems, computing devices, and computer-readable media (transitory and non-transitory) are described herein for analyzing execution of a plurality of executable instructions and, based on the analysis, providing an indication of a benefit to be obtained by vectorization of at least a subset of the plurality of executable instructions. In various embodiments, the analysis may include identification of the subset of the plurality of executable instructions suitable for conversion to one or more single-instruction multiple-data (“SIMD”) instructions.

    Abstract: Example methods and apparatus to manage object locks are disclosed. A disclosed example method includes intercepting a processor request to apply the lock on the object, identifying a performance history of the object based on a number of instances of contention, reducing computing resources of the processor by, when the number of instances is below a threshold value, generating a lock bypass for the object to cause speculative execution of target code within the object, and preventing speculative execution by applying the lock on the object when the number of instances is above the threshold value.

    Abstract: In one embodiment, a processor can operate in multiple modes, including a direct execution mode and an emulation execution mode. More specifically, the processor may operate in a partial emulation model in which source instruction set architecture (ISA) instructions are directly handled in the direct execution mode and translated code generated by an emulation engine is handled in the emulation execution mode. Embodiments may also provide for efficient transitions between the modes using information that can be stored in one or more storages of the processor and elsewhere in a system. Other embodiments are described and claimed.

    Abstract: An inter-architecture compatibility apparatus of an aspect includes a control flow transfer reception module to receive a first call procedure operation, intended for a first architecture library module, from a first architecture code module. The first call procedure operation involves a first plurality of input parameters. An application binary interface (ABI) change module is coupled with the control flow transfer reception module. The ABI change module makes ABI changes to convert the first call procedure operation involving the first plurality of input parameters to a corresponding second call procedure operation involving a second plurality of input parameters. The second call procedure operation is compatible with a second architecture library module. A control flow transfer output module is coupled with the ABI change module. The control flow transfer output module provides the second call procedure operation to the second architecture library module.
