I'm seeing the same problems on Tru64 UNIX.  I've used the attached patch to
avoid the ICE and provide a sane default in default_clone_table_section.

Created attachment 26114
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26114
proposed minimal patch

With this patch, the only remaining TM failure on Tru64 UNIX is 

FAIL: libitm.c/clone-1.c execution test

as expected.

While that might solve the ICE, the clone table doesn't actually
get registered, which is why that clone-1 test case still fails.

You'll need to play with collect2 and all its magic symbols to
get that to work.

Of course, you mentioned that already.  Unfortunately, I didn't have
much time for gcc work lately and don't know when I get around to it.
The hack I posted is certainly better than tons of ICEs when trying to
keep track of testsuite failures.

I need to determine whether it's possible to support the section changes
needed for itm on 32-bit hppa*-*-hpux*.   Placement is critical (i.e.,  
we
can't support changes to a named section mid function).  I was thinking
of defining pa_no_named_section to do this.  I definitely can't enable
named sections as this would create many other problems.  Effectively,
I need selective support for named sections.

I did disable -fgnu-tm on the above target.  This fixes the ICE but I'm
still left with the testsuite failures.

The attached patch seems to fix the tm test failures.  However, it  
needs a bit more testing
and I don't understand the registration magic.

What's the status of this report?
Do all libitm tests passed on PA? 
Does it still not working on Tru64 UNIX?

Thanks.

All tm tests pass on PA (well, there is one that fails on 32-bit HP-UX 
due to the limited
alignment of common.  -fno-common should fix this).  As of now, I 
haven't had a chance
to try porting libitm to hppa-linux.  I'm not sure it can be ported to 
hppa-hpux.

libitm.c/clone-1.c still doesn't work on Tru64 UNIX, and cannot as Richard
mentioned on platforms without named section support.  I didn't get around to
investigate the collect2 route yet.

Without my proposed patch (hack, actually), all tm patches ICE on Tru64 UNIX.

Tru64 has been deprecated.  Since this has been fixed for HPUX,
there are no more live systems with the problem.
