--- Comment #2 from Steve Ellcey <sje at cup dot hp.com> 2011-06-21 15:48:14 UTC --- I built an hppa2.0w-hp-hpux11.11 compiler with --disable-bootstrap and then ran the test suite to see if I could get a smaller test case. The tests are still running but there are many failures with -O1 and higher levels of optimization. One small example is gcc.c-torture/execute/20000717-1.c, which fails during execution at -O1, -O2, -O3, -Os. Here are some other tests that fail at -O1: FAIL: gcc.c-torture/execute/20000706-1.c execution, -O1 FAIL: gcc.c-torture/execute/20000706-2.c execution, -O1 FAIL: gcc.c-torture/execute/20000706-5.c execution, -O1 FAIL: gcc.c-torture/execute/20000717-5.c execution, -O1 FAIL: gcc.c-torture/execute/20011113-1.c execution, -O1 FAIL: gcc.c-torture/execute/20020215-1.c execution, -O1
