Now the testresult for hppa64-hp-hpux11.11 looks good
http://gcc.gnu.org/ml/gcc-testresults/2011-08/msg00952.html

I'd like to close this PR.

Likely.  Sounds like the usual ungraceful failure of dejagnu to find the
baseboard file: it just tries to execute the file natively and then oddly times
out instead of just failing; note lack of "cris-axis-elf-run" calls in the
.log files.  That is, if you're running dejagnu-1.4.4 or earlier;
dejagnu-1.5 should already have the baseboard.  For future reference,
.

I've got

FAIL: gcc.dg/cleanup-10.c execution test
FAIL: gcc.dg/cleanup-11.c execution test

FAIL: g++.dg/eh/crossjump1.C execution test
FAIL: g++.dg/eh/unexpected1.C execution test

...

A tiny testcase in #1 of PR49686

int foo (int a)
{
  if (a)
bar ();
  return 1;
}

is again compiled to

foo:
.LFB0:
tstr4,r4
bt/s.L2
sts.lpr,@-r15
mov.l.L3,r0
jsr@r0
nop

with -O1 -fexceptions -fnon-call-exceptions.

The problem looks to be in libgcc:

Program received signal SIGSEGV, Segmentation fault.
0xc0091924 in _Unwind_DeleteException (exc=0x8001a090)
 at ../../../gcc/libgcc/../gcc/unwind.inc:271

David, most of those c++ tests require system headers to compile,
but g++.old-deja/g++.robertl/eb31.C does not.

Except that I don't see any changes to unwind info in any delay
slots for that test case, so I'm particularly confused about what
could have gone wrong with that test.  Does it work without delayed
branches?

Or is the problem in fact in libgcc somewhere?  I.e. you have to
compile libgcc with -fno-delayed-branch in order to fix things?

Mine.

Kaz, can you enumerate some specific tests that are now failing?
It'll save me time trying to track down the problem.  E.g. a cross
to CRIS is hanging in the simulator for *every* execution test,
so I assume there's something wrong with my cris-sim dejagnu setup.
I havn't tried sh-sim yet, but will do so while looking at hppa...
