If darwin doesn't care about the PR other/26208 problem, it can certainly
just #define _Unwind_GetIPInfo(ctx, ip) (*(ip) = 0, _Unwind_GetIP (ctx)
in its own unwind.h or something similar.
But if it cares, it needs to allow libgcc_s symbol additions.

------- Comment #2 from geoffk at gcc dot gnu dot org 2006-06-06 01:17 -------
Clearly, we cannot add any symbols to the 10.4 libgcc_s. 10.4 has already
shipped, and we do not have a time travel device.
By default, gcc compiles for the earliest OS version it knows about. For C++,
that means 10.3.9/10.4. This is best for users.
Thus, by default, you cannot use any new symbols in libgcc_s.
The problem occurs because libstdc++ wants to use the new symbol by default. I
can think of a bunch of solutions to the problem:
1. Have libstdc++ use autoconf to detect the presence of the new symbol and use
it only if it exists.
2. Decide that the purpose of libstdc++ is to be installed only on new (not yet
existing) system versions, and pass appropriate flags to the compiler to make
this happen. Of course, this might make testing hard for people still using
10.4.
3. Decide that libstdc++ and libgcc go together, and hack libstdc++'s link to
use libgcc_s.1.dylib directly. Apple doesn't do this internally, we're
shipping 4.0.0 libstdc++ and 4.0.1 libgcc. Apple's libstdc++ is binary
incompatible with FSF libstdc++ (in small but important ways) and so the effect
of this might be that no-one can use FSF libstdc++ or FSF libgcc on Darwin at
all.
4. Declare that we don't care. The problem right now affects only people with
the MACOSX_DEPLOYMENT_TARGET environment variable set which they probably
shoudn't have set while building FSF GCC.
I think we should go for (1), although (4) has certain advantages...

------- Comment #3 from howarth at nitro dot med dot uc dot edu 2006-06-13 02:10 -------
It appears that on Macintel, simply unsetting MACOSX_DEPLOYMENT_TARGET is
insufficient to
eliminate the undefined symbols for _Unwind_GETIPInfo when building gcj. This
doesn't happen
on ppc Darwin. Currently the fink developers have decided to leave
MACOSX_DEPLOYMENT_TARGET set to 10.4 and use the
http://gcc.gnu.org/ml/gcc-patches/2006-02/msg02041.html patch. Would it be
better for them to unset MACOSX_DEPLOYMENT_TARGET
and use Jakub's recommendation of adding...
#define _Unwind_GetIPInfo(ctx, ip) (*(ip) = 0, _Unwind_GetIP (ctx)
to a darwin specific unwind.h? I am trying to get them from forking the
libstdc++ in fink.

------- Comment #4 from howarth at nitro dot med dot uc dot edu 2006-06-13 16:44 -------
Geoff,
Does any other os, that uses gcc, version libgcc_s in the manner that Apple
does?
Simply not setting MACOSX_DEPLOYMENT_TARGET during the build of gcc 4.2 doesn't
make the problem go away. The resulting libstdc++.6.dylib and libgcc_s.1.dylib
libraries
have _Unwind_GetIPInfo symbols whereas libgcc_s.10.4.dylib and
libgcc_s.10.5.dylib
don't. This precludes safely using MACOSX_DEPLOYMENT_TARGET at all with gcc
4.2.
I know you said you won't assign this to yourself until it happens to you.
However it
isn't happening to you because you don't want it to. Apple really needs to deal
with the
breakage caused by their decision to version libgcc_s.

Created an attachment (id=11724)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=11724&action=view)
libstdc++ macro to test for _Unwind_GetIPInfo
I have attached a macro that could be put in libstdc++-v3/acinclude.m4 and
called from configure to check for the existence of _Unwind_GetIPInfo. I
haven't submitted it as a patch because I don't know how to handle Java.
libjava also uses _Unwind_GetIPInfo but the java configure script doesn't seem
to allow for compiling and linking test programs in order to check for
routines.

------- Comment #8 from howarth at nitro dot med dot uc dot edu 2006-07-19 23:25 -------
I can confirm on MacOS X 10.4 that Steve's proposed patch works fine
with the current gcc trunk. I can successfully bootstrap while
MACOSX_DEPLOYMENT_TARGET is set to 10.4 and no regressions
occur when the 'make check' is done afterwards without
MACOSX_DEPLOYMENT_TARGET being set. Only libgcc_s.1.dylib
ends up with __Unwind_GetIPInfo being defined. The libgcc_s.10.4.dylib
and libgcc_s.10.5.dylib files do not. However I guess we should ask
Geoff if Apple would like __Unwind_GetIPInfo defined in libgcc_s.10.5.dylib
since that library is unreleased.

We can't define __Unwind_GetIPInfo in libgcc_s.10.5.dylib at this time. If we
create a situation in which we can, rest assured, we will.

Actually libstdc++ is only part of the problem, the other part is libjava.
Eric if you are going to close something, you should test it.

------- Comment #15 from sje at cup dot hp dot com 2006-09-11 22:31 -------
Bryce, have you looked at ifdef'ing the use of _Unwind_GetIPInfo in the Java
library? Would you be willing to do so? I have created an autoconf test
(GCC_CHECK_UNWIND_GETIPINFO) in trunk/config/unwind_ipinfo.m4 and the C++
runtime library is checking for HAVE_GETIPINFO before using it. I believe the
un-ifdef'ed use of this function in the java library is the reason this PR is
still open.

Is this what we are waiting for? I came up with that by just placing
wrappers around the changes submitted on...
http://gcc.gnu.org/viewcvs/trunk/libjava/stacktrace.cc?r1=115069&r2=115235&pathrev=115235
and
http://gcc.gnu.org/bugzilla/attachment.cgi?id=10915
so that the previous code was in place when HAVE_GETIPINFO is false.

Yes, I think the #ifdef is a reasonable solution. Stack traces will be
inaccurate when GetIPInfo is unavailable, but I don't see any easy way around
that.

------- Comment #19 from howarth at nitro dot med dot uc dot edu 2006-09-18 04:40 -------
Tested the patch on Darwin 8 with no regressions. Verified that the
_Unwind_GetIPInfo
symbols are absent for libgcj with HAVE_GETIPINFO undefined. While the patch is
over
10 lines, I would argue that I only wrote the lines with the preprocessor
statements and
the rest is simply a return of previously existing code from others.

I'll test that with tonight's gcc trunk build using MACOSX_DEPLOYMENT_TARGET
unset which should create both a libstdc++ and libgcj with the
_Unwind_GetIPInfo

Okay, the autoconf changes for libstdc++ and libgcj actually work okay.
The test program uses the static libgcc.a to link (which lacks the
__Unwind_GetIP symbol) so that HAVE_GETIPINFO remains undefined regardless of
whether MACOSX_DEPLOYMENT_TARGET is set or not. I believe this is the behavior
we want on Darwin since the alternative of allowing MACOSX_DEPLOYMENT_TARGET
unset to cause __Unwind_GetIP to be used in libstdc++ and libgcj would create
libraries that couldn't be used when MACOSX_DEPLOYMENT_TARGET was set to 10.4
or 10.5. I'll post the patches to gcc-patches shortly.

------- Comment #30 from schwab at suse dot de 2007-03-31 10:57 -------
The configure check is finding the definition of _Unwind_GetIPInfo in libgcc_s
(from unwind-compat.o) when configuring with --with-system-libunwind.

When configuring with --with-system-libunwind, GCC should not include
unwind-compat.o (or any unwind code) in the build of libgcc_s. Then the
configure check will work correctly.

unwind-compat is _required_ for the system libunwind.

Geoff, do you intend to backport these Darwin patches to 4.2.0?

I don't know what patches you're referring to, so no.

Mark,
Are you under the impression that the libstdc++-v3 and libjava patches were
only applied to trunk? That isn't the case as those went into 4.2 branch some
time ago as r115654 and r117259. The only
outstanding issue I see is comment 31 which doesn't seem to be Darwin specific.

Steve,
Does this problem merit a P1 blocker status? For that specific issue,
can't we
downgrade this bug report to P2? Is it essential that --with-system-libunwind
work in gcc 4.2.0 or could that just be retargeted for gcc 4.2.1?

I think a non-working --with-system-libunwind corner case on darwin is a P4 at
best?

Mike,
Why don't you close this report as RESOLVED and create another one just for
the non-working --with-system-libunwind issue as a P4. That might help prevent
folks from constantly reopening this PR as a P1.
