Patent number: 9195486Abstract: Observation and analysis based optimization of software code is disclosed. An expected value is chosen for a dynamic attribute that cannot be determined, prior to execution of the associated software code, to be guaranteed to have that expected value at runtime. An optimized version of the software code is generated, including one or more optimizations based on an assumption that the dynamic attribute will have the expected value. Non-exhaustive examples of a dynamic attribute include a variable type; a location in memory; a location in which a global object, property, or variable is stored; the contents of a global function or method; and a value of a global property or variable. A check is performed during execution of the optimized version of the software code, prior to executing the portion that has been optimized based on the assumption, to verify that the dynamic attribute has the expected value.Type: GrantFiled: July 30, 2010Date of Patent: November 24, 2015Assignee: Apple Inc.Inventors: Victor Leonel Hernandez Porras, Christopher Arthur Lattner, Jia-Hong Chen, Eric Marshall Christopher, Roger Scott Hoover, Francois Jouaux, Robert John McCall, Thomas John O'Brien, Pratik Solanki

Patent number: 9146759Abstract: Techniques for processing source code written in a traditionally interpreted language such as JavaScript, or another dynamic and/or interpreted language, are disclosed. In one example, compiled code associated with the source code is constructed and executed. An assumption on which a specific aspect of the compiled code is based (e.g., an optimization) is tested at a checkpoint of the compiled code. A roll over to fallback code is performed if the test indicates the assumption is not true.Type: GrantFiled: July 30, 2010Date of Patent: September 29, 2015Assignee: Apple Inc.Inventors: Victor Leonel Hernandez Porras, Christopher Arthur Lattner, Jia-Hong Chen, Eric Marshall Christopher, Roger Scott Hoover, Francois Jouaux, Robert John McCall, Thomas John O'Brien, Pratik Solanki
