------- Additional Comments From vda at port dot imtp dot ilyichevsk dot odessa dot ua 2005-04-21 13:36 ------- testcase is measuring how many twofish_setkey()'s can be executed per second. By inserting extra 'return 0;' in the body of that function and running the testcase, we can measure where it spends most of the execution time.
Testcase already has such return (and large comment) exactly after for() loop which runs much faster in non-optimized compile. Move "return 0" above the loop and things return to normal (-O2 is faster than non-optimized). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21147
