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
