  • Methods for performining cross module context-sensitive security analysis
    Patent number: 7971193
    Abstract: A computer-implemented method for detecting program bugs in source code of a computer program that includes a plurality of source modules, each of the plurality of source modules including at least a set of subroutines, is provided. The method includes performing summary collection on subroutines of the plurality of source modules. Performing the summary collection includes collecting first data pertaining to at least untrusted data in each of the subroutines of the plurality of source modules. The method also includes storing the first data in a set of intermediate files. The method further includes performing interprocedural analysis on the set of intermediate files. The interprocedural analysis is configured to identify at least first untrusted data in a given subroutine of the subroutines of the plurality of source modules and to map a data flow tracking the first untrusted data across at least two of the plurality of source modules.

  • Circular scheduling method and apparatus for executing computer programs by moving independent instructions out of a loop
    Patent number: 5386562
    Abstract: A procedure which is a particular type of software pipelining is provided which increases the efficiency with which code is executed by reducing or eliminating stalls such as by filling delay slots. The process includes moving instructions in a loop from one loop iteration to another. The moving of instructions provides the scheduler with additional independent instructions in a given basic block so the scheduler has greater freedom to move instructions into unfilled delay slots. The procedure includes changing the entry point into the loop, thus effectively moving an instruction from near the top of the loop to near the bottom of the loop, while changing the iteration number of the moved instruction.
