20 | # programs compiled with profile-directed optimizations. Compile and | |
21 | # run a test with profile options, compile it with options using the | |
22 | # profile feedback, and then run the test again. Optionally compile | |
23 | # and run a third time without the profile-directed optimization and | |
24 | # compare timing results of the program with normal optimization and | |
25 | # with the profile-directed optimization. Each test is run using | |
