James I.A. Gartley has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Efficient interpreter profiling to obtain accurate call-path information
    Patent number: 9417856
    Abstract: A method for obtaining accurate call path information in a mixed-mode environment where interpreted methods and non-interpreted methods can call one another is disclosed. In one embodiment, such a method includes generating an event and recording it in a buffer when an interpreted method calls an interpreted method. The method also generates an event and records it in the buffer when an interpreted method calls a non-interpreted method. The method further generates an event and records it in the buffer when a non-interpreted method calls an interpreted method. The method refrains from generating an event when a non-interpreted method calls a non-interpreted method. A corresponding apparatus and computer program product are also disclosed.

  • Partial inlining with software based restart
    Patent number: 8701097
    Abstract: A compiler and method of optimizing code by partial inlining of a subset of blocks of called blocks of code into calling blocks of code. A restart of the called blocks of code is provided for the case where non-inlined blocks of code are reached at run time. Blocks selected for partial inlining may include global side effects depending on the computer program environment. Global side effects in the selected blocks of code leading to a restart are sanitized in order to defer changes to the global state of the computer program.
