Method and apparatus for optimizing time and testing of higher level language program

摘要

A method for time use analysis of a higher level language program is performed by displaying source code lines in descending order according to the amount of time spent by the program to execute machine code into which the source code lines have been compiled. Source code lines are displayed arranged in order according to the percentages of the amounts of time spent in execution during runs of the program, and the higher percentages identified for optimizing actions. A digital processing apparatus for performing the analysis includes a display for showing the source code lines that require the most time of execution, a selection apparatus for selecting those source code lines having the greater opportunity for significant corrective action, and displaying the various selected source code lines in the order in which the lines are kept in the program along with the corresponding time spent by the program to execute machine code into which the source code lines have been compiled. An improved method and apparatus identifies source code lines which a testing program does not test in its test procedure. A digital processing apparatus displays in different orders those source code lines identified as not having been used. Test programs are improved so that machine code instructions for all lines of source code are executed.
