Appl. No.:

11/673905

Inventors:

Yuguang Wu - Mountain View CA, US
Jin Lin - San Jose CA, US

Assignee:

Oracle America, Inc. - Redwood City CA

International Classification:

G06F 15/00
G06F 9/30
G06F 9/40

US Classification:

712216

Abstract:

A system and method for aggressive loop parallelization using speculative execution is disclosed. The method may include transforming code of a target application for concurrent execution, which may include adding an instruction to create a global address table entry for each store operation on which a load operation of a different loop iteration is dependent. The method may include replacing a standard load instruction with a special instruction configured to determine if an operand address of the load matches an operand address in one of the global address table entries. Another special instruction may remove a table entry following execution of the corresponding store operation. If an operand address of a load of a currently executing thread matches an operand address in the global address table, the method may include setting a checkpoint, completing execution of the thread in a pre-fetch mode, and re-executing the thread from the checkpoint.

International Classification:

G06F 9/45

US Classification:

717160, 717159

Abstract:

Methods to improve optimization of compilation are presented. In one embodiment, a method includes identifying one or more optimization speculations with respect to a code region and speculatively performing transformation on an intermediate representation of the code region in accordance with an optimization speculation. The method includes generating an advice message corresponding to the optimization speculation and displaying the advice message if the optimization speculation results in an improved compilation result.

International Classification:

G06F 21/54

G06F 9/48

Abstract:

Enforcing shadow stack violations at module granularity, rather than at thread or process granularity. An exception is processed during execution of a thread based on code of an application binary, which is enabled for shadow stack enforcement, that calls an external module. The exception results from a mismatch between a return address popped from the thread's call stack and a return address popped from the thread's shadow stack. Processing the exception includes determining that the exception resulted from execution of an instruction in the external module, and determining whether or not the external module is enabled for shadow stack enforcement. Based at least on these determinations, execution of the thread is terminated when the external module is enabled for shadow stack enforcement, or the thread is permitted to continue executing when the external module is not enabled for shadow stack enforcement.

International Classification:

G06F 21/31

Abstract:

Disclosed herein is a technique that can selectively display secure content on a computing device. The technique can detect both lock and unlock events and issue appropriate control signals that cause an application to display a more secure version of the application when necessary based on a particular UI context file. The UI context file can specify a configuration that includes pre-configured hidden or removed UI elements that do not need to be adjusted at runtime. Moreover, the technique can seamlessly pivot to a different UI context file that specifies a configuration of the application that allows the user to experience the full-capabilities of the application when the computing device is in an unlocked-mode.
