Profile instrumentation method and profile data collection method

A profile data collection method in which profile data are obtained and collected during the execution of a program so as to grasp the behavior of the program, comprising:

• setting a stack area adapted to be used in determining caller procedure, a heap area adapted to be used in allocating profile data records, and a table in a dynamic array data structure;
• profiling the program including inserting instrumentation code into the program for instructing collection of profile data during execution of the program;
• and
• collecting the profile data in response to the instrumentation code while data storage processing is performed so as to store the profile data into said stack area, said heap area, and said table.

A profile data collection method in which profile data are obtained and collected during the execution of a program so as to grasp the behavior of the program, wherein

• a stack area, a heap area, and a table are previously set on a dynamic array data structure;
• when profiling is performed so as to collect profile data, data storage processing is performed so as to store data regarding said profiling into said stack area, said heap area, and said table;
• at the beginning of measurement of profile data, information regarding an object to be profiled is pushed into said stack area, and at the end of said measurement, said information is popped from said stack area;
• a profile data record obtained via measurement is written into said heap area;
• and
• the caller-callee relationship of functions subjected to profiling is written into said table so as to hold these data.

A profile data collection method in which profile data are obtained and collected during the execution of a program so as to grasp the behavior of the program, wherein

• a stack area, a heap area, and a table are previously set on a dynamic array data structure;
• when profiling is performed so as to collect profile data, data storage processing is performed so as to store data regarding said profiling into said stack area, said heap area, and said table;
• and
• initialization processing for securing areas for said stack area, said heap area and said table, and cleanup processing for cleaning up said stack area, said heap area and said table after completion of said profiling are both executed independently of program execution processing including said profiling.
