  • Patent number: 10877757
    Abstract: A just-in-time (JIT) compiler binds constants to specific memory locations at runtime. The JIT compiler parses program code derived from a multithreaded application and identifies an instruction that references a uniform constant. The JIT compiler then determines a chain of pointers that originates within a root table specified in the multithreaded application and terminates at the uniform constant. The JIT compiler generates additional instructions for traversing the chain of pointers and inserts these instructions into the program code. A parallel processor executes this compiled code and, in doing so, causes a thread to traverse the chain of pointers and bind the uniform constant to a uniform register at runtime. Each thread in a group of threads executing on the parallel processor may then access the uniform constant.

  • Patent number: 10705685
    Abstract: A graphical user interface (GUI) can be tested using a navigation system to access objects. As an example, a processing device in a system can receive a selection of an object. The selection can be made through the GUI. In response to the selection, the processing device retrieves the object and a destination at which the object is located. The processing device recursively traverses a backwards navigation path from the destination to the graphical user interface using the name of the object and the destination. The processing device can then navigate to the destination using the backwards navigation path.

  • Patent number: 10642587
    Abstract: Technologies for indirectly calling vector functions include a compute device that includes a memory device to store source code and a compiler module. The compiler module is to identify a set of declarations of vector variants for scalar functions in the source code, generate a vector variant address map for each set of vector variants, generate an offset map for each scalar function, and identify, in the source code, an indirect call to the scalar functions, wherein the indirect call is to be vectorized. The compiler module is also to determine, based on a context of the indirect call, a vector variant to be called and store, in object code and in association with the indirect call, an offset into one of the vector variant address maps based on (i) the determined vector variant to be called and (ii) the offset map that corresponds to each scalar function.

  • Patent number: 10642724
    Abstract: Technologies for bridging trace gaps include a computing device that traces execution of a program to generate an execution trace and identifies a trace gap in the execution trace. The computing device generates a first call stack that corresponds to a location immediately before the trace gap and a second call stack that corresponds to a location immediately after the trace gap. Each call stack identifies a list of functions, and each function corresponds to a source function of the program. The computing device evaluates connection pairs between the first call stack and the second call stack to determine whether each connection pair is valid and, for each valid connection pair, a number of matching functions. The computing device selects a connection pair that is valid and has a largest number of matching functions and bridges the trace gap with the selected connection pair. Other embodiments are described and claimed.

  • Patent number: 10546130
    Abstract: A Timed Attestation Process (TAP) utilizes a CPU bus cycle counter/timer to accurately measure the time needed to calculate a specific function value for an attestation query in an embedded system. The attestation query takes into account embedded software and the hardware data path. An attestation value database stores the unique timing and function data associated with each hardware design element in the embedded device, which each have unique timing characteristics. By utilizing the CPU bus cycle counter/timer of the client device, the TAP increases the time accuracy to the smallest tolerance possible relative to a particular CPU (typically +/?one instruction cycle). The integrity of the embedded software contained in the permanent storage elements and the hardware timing to access each component is verifiable against the unique timing characteristics stored in the database. With this timing characteristic, each hardware element is linked to a specific software configuration.

  • Patent number: 10545744
    Abstract: A sequence of input language (IL) instructions of a guest system is converted, for example by binary translation, into a corresponding sequence of output language (OL) instructions of a host system, which executes the OL instructions. In order to determine the return address after any IL call to a subroutine at a target entry address P, the corresponding OL return address is stored in an array at a location determined by an index calculated as a function of P. After completion of execution of the OL translation of the IL subroutine, execution is transferred to the address stored in the array at the location where the OL return address was previously stored. A confirm instruction block is included in each OL call site to determine whether the transfer was to the correct or incorrect call site, and a back-up routine is included to handle the cases of incorrect call sites.
