    Abstract: A malicious object detection system for use in managed runtime environments includes a check circuit to receive call information generated by an application, such as an Android application. A machine learning circuit coupled to the check circuit applies a machine learning model to assess the information and/or data included in the call and detect the presence of a malicious object, such as malware or a virus, in the application generating the call. The machine learning model may include a global machine learning model distributed across a number of devices, a local machine learning model based on use patterns of a particular device, or combinations thereof. A graphical user interface management circuit halts execution of applications containing malicious objects and generates a user perceptible output.

    Abstract: State recovery methods and apparatus for computing platforms are disclosed. An example method includes inserting, with a processor, a first instruction into optimized code to cause a first portion of a register in a first state to be saved to memory before execution of a region of the optimized code, maintaining, with the processor, a first indication of a first manner in which the first portion of the register is to be restored in connection with a state recovery after execution of the region of the optimized code, and maintaining, with the processor, a second indication of a second manner in which a second portion of the register is to be restored in connection with the state recovery after execution of the region of the optimized code.

    Abstract: Technologies for native code invocation using binary analysis are described. A computing device for invoking native code from managed code using binary analysis receives a call from a thread executing a managed code segment to execute a native code segment. The computing device performs a binary analysis of the native code segment and generates, from the binary analysis, a complexity indicator that indicates a level of complexity of the native code segment by comparing the native code segment to at least one predefined complexity rule. Additionally, the computing device stores a status of the thread based on the complexity indicator and executes the native code segment. Other embodiments are described and claimed.

    Abstract: A vector reduction instruction is executed by a processor to provide efficient reduction operations on an array of data elements. The processor includes vector registers. Each vector register is divided into a plurality of lanes, and each lane stores the same number of data elements. The processor also includes execution circuitry that receives the vector reduction instruction to reduce the array of data elements stored in a source operand into a result in a destination operand using a reduction operator. Each of the source operand and the destination operand is one of the vector registers. Responsive to the vector reduction instruction, the execution circuitry applies the reduction operator to two of the data elements in each lane, and shifts one or more remaining data elements when there is at least one of the data elements remaining in each lane.

    Abstract: A data processing system (DPS) supports control-flow integrity (CFI). The DPS comprises a processing element with a CFI enforcement mechanism that supports one or more CFI instructions. The DPS also comprises at least one machine-accessible medium responsive to the processing element. Managed code in the machine-accessible medium is configured (a) to execute in a managed runtime environment (MRE) in the data processing system, and (b) to transfer control out from the MRE to unmanaged code, in response to a transfer control statement in the managed code. The machine-accessible medium also comprises a binary translator which, when executed, converts unmanaged code in the data processing system into hardened unmanaged code (HUC) by including CFI features in the HUC. The CFI features comprise one or more CFI instructions to utilize the CFI enforcement mechanism of the processing element for transfers of control initiated by the HUC. Other embodiments are described and claimed.
