Gcc mainline failed to bootstrap on Linux/ia64

[H. J. Lu]

Gcc mainline on Sat Sep  6 07:08:21 PDT 2003 failed to bootstrap on
Linux/ia64. I got

This appears to be related to change of mine to notice_global_symbol.
I just commited fix to different problem that may fix it.  Can you
please ensure that the following patch is in your tree?
       * cgraph.c (cgraph_mark_reachable_node): Only enqueue finalized functions.
       (cgraph_varpool_finalize_decl): Notice global symbol when needed.

The current mainline, on Sat Sep  6 23:22:22 UTC 2003, is even worse.

I am just testing the attached patch I will commit as obvious if it
passes.
It should help you too.

See the same 'hanging' on ppclinux and solaris 2.9.

I saw the hang problem on solaris2.7, but Jan's patch here fixed it.
http://gcc.gnu.org/ml/gcc/2003-09/msg00332.html

Andreas and HJ, you may have still seen the problem because Jan
installed his patch on mainline just now, several hours after
installing it on 3.3.x.  Can you please reconfirm with current
mainline CVS?

Hm, ok, ppclinux build in progress. Sol 2.9 syncing. Let you know asap.

Sorry, for the delay. My new hppa needs some config :)

Thanks anyway.

For the record, solaris in stage 3 now. Was hanging before in stage 2.

Further info coming.

Here it is:

ppc linux now in stage of building the libs (libgcj at the moment). 
Solaris 2.9 died in libstdc++ with the filed (12126) bug.
Darwin building, but I had a hanger in libgcj.

Honza, thanks & sorry for bothering you!

Situation is very unstable on every arch I have. (BE)

Andreas

P.S Kaveh, mail delivery probs on your account.

Excellent.

Definitly no need to apologize :) thanks for usefull testing and
feedback!  The unit-at-a-time change brings me number of headaches by
being able to uncover really a lot of latent bugs and design issues.
Hope to get into end of that soon.

This is still not fixed.

Can you please send me something more specific (such as a bracktrace?)
I can't build on IA-64 myself right now...

This testcase triggers ill defined behaviour and probably should be
turned into hard error, unfortunately I still don't know how to do that
without breaking glibc yet.

I will take look on the 20000120-2.c and install the patch as obvious.
Thanks!

That can be great.  Let me know if you find it realted to unit-at-a-time
code.

are failing on a lot of systems and have been for a while.  In fact, they
all fail on AIX as well. The testcases are questionable.

	The libffi testcases were added since your last bootstrap.  Do the
failures report cgraph problems?

I see now failure of 20011119-1.c on i386 too.  The problem is that
re-definition of function kills the saved function body:

extern inline int foo (void) { return 23; }
int xxx(void) __asm__("xxx");
int xxx(void) { return 23; }
extern int foo (void) __attribute__ ((weak, alias ("xxx")));

I do have patch to keep it (attached), but I am not convienced that it
is good idea to allow such a construct.  Would be possible to error on
this?   If so, any idea what exactly test?  Or does the attached patch
look OK?
