http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49454 --- 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/2717-1.c, which fails during execution at -O1, -O2, -O3, -Os. Here are some other tests that fail at -O1: FAIL: gcc.c-torture/execute/2706-1.c execution, -O1 FAIL: gcc.c-torture/execute/2706-2.c execution, -O1 FAIL: gcc.c-torture/execute/2706-5.c execution, -O1 FAIL: gcc.c-torture/execute/2717-5.c execution, -O1 FAIL: gcc.c-torture/execute/2003-1.c execution, -O1 FAIL: gcc.c-torture/execute/20020215-1.c execution, -O1

I assumed so. Richard's comments regarding the patch indicated that it was unlikely to fix all the problems on hppa (a callee copies target). Dave
