Mark J. Wielaard 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).

  • Preloading unwind data for non-intrusive backtracing
    Patent number: 9111036
    Abstract: An unwind data system stores unwind data for a target module in memory pages in main memory prior to an introspection tool making an attempt to generate a backtrace for the target module. The unwind data system detects a trigger in a user script, which includes instructions to generate a backtrace for the target module using the introspection tool. The trigger corresponds to a section of software code of the target module. The unwind data system locates the unwind data in the memory pages in the main memory for the section of software code of the target module and unwinds the section of software code to generate a backtrace using the unwind data located in the memory pages in the main memory.

  • Generating backtracing information for software debugging of software programs running on virtual machines
    Patent number: 8701088
    Abstract: A mechanism for generating backtracing information for software debugging of software programs running on virtual machines. A method of embodiments of the invention includes probing a virtual machine of a computer system, the virtual machine to run a software program, accessing compiler-generated output at a storage medium of the computer system, the compiler-generated output having debug information relating to the virtual machine, and obtaining the debug information from the compiler-generated output. The method further includes generating backtracing information of the software program using the debug information, and providing the backtracing information for debugging of the software program.
