I'll have a go at duplicating your results, then have a go at extending the test case coverage. A pretty obvious first question would be: How much better test coverage would you get if you ran the test cases with -O3, something like this: [dcb30@localhost trunk]$ cd gcc/testsuite/ [dcb30@localhost testsuite]$ for i in `find . -name \*.c -print | sort` > do > echo $i > $TEST_COMPILER -c -O3 -Wall $i > done I am assuming that there is no easy flag on the testsuite to compile everything with -O3 instead of whatever flags each test case wants.
