[Bug c++/19159] [4.0/4.1 Regression] Undefined symbol: vtable for __cxxabiv1::__vmi_class_type_info

[mmitchel at gcc dot gnu dot org]

--- Comment #34 from mmitchel at gcc dot gnu dot org  2005-10-31 02:08 
---
According to the thread starting with the reference in Comment #31, this is
just a spurious warning on systems without weak symbols.  As such, it's never
going to be release-critical.

The two leading proposals were made for resolving the problem: (1) use a
dynamic initialization on systems without weak symbols, or (2) warn only if the
static variable is actually addressed, as otherwise the fact that there are
multiple copies doesn't matter.  I agree with Jason that (2) is the best
option, and it should be relatively easy to implement, given that we already
mark things as addressed; we could just move the warning to that location.

The remaining failures are all either due to (a) defects in the V3 testsuite, or
(b) defects in V3 itself, or (c) semi-spurious warnings in the C++ front end.

Postponed until GCC 4.0.1.

I would think this is the same as PR 20584 where there is a testcase but nobody 
has reduced it since it 
has to do with "#pragma implementation" and if you get rid of all the file 
markers aka "# file line", it 
goes away.

The warnings are from GCC:

ginyu% grep "used but never defined" *.c
decl2.c:  cp_warning_at ("inline function %qD used but never defined", 
decl);

You could be right that this is a PCH problem and possibly configuring
with --disable-libstdcxx-pch would help.

I suspect that there is some PCH involvement here.  In particular, the warnings
you're seeing while compiling header_cassert are very surprising, in that the
preprocessed source for that file does not contain the string "_S_do_it".  So, I
think the problem is related to PCH.  To fix that, I'll need a test case that I
can reproduce in a cross environment; i.e., preprocessed source that I can turn
into a PCH, and then some use of the PCH that produces the warnings.

In any case, I'm going to test, and then check in, the latest patch, as lots of
link-time warnings is better than link failures.

Thanks for clarifying that you are only seeing warning messages.

That indicates that I've probably fixed the original bug, but there is some kind
of secondary bug.  I will see if I can reproduce.

The _S_do_it reference appears in a .stabx directive:

.stabx  
"_Array_copy_ctor:Tt1478=s1_S_do_it::1479=f-11:_ZNSt16_Array_copy_ctorImLb1EE8_S_do_itEPKmS2_Pm;2A?;;",0,140,0

Just a note, the failures were caused by "used but never defined"
warnings.  I didn't look at all the fails but I didn't see any
link failures with your latest patch.

Dave, I think that the problem with _S_do_it is an entirely separate bug.  In
particular, V3 builds with -fno-inline-templates, but does not use
-fno-implicit-inline-templates.  The _S_do_it function is inline.  Since AIX
does not have weak symbols, we probably make that function have internal linkage
in the library, which causes the link failures you're seeing.

To confirm that, would you please send me the preprocessed version of both 
valarray-inst.cc and header_cassert.cc, together with the cc1plus command-line
used on AIX to compile each?

Thanks,

Dave --

I've finally got a new version of the patch.  I've played with it some, and I
feel like it ought to work, but maybe I'm still missing something.  If it
doesn't work, would you mind attached preprocessed source for tinfo.cc and
tinfo2.cc from libsupc++?  These are the files where the type info vtables ought
to be defined.  That would make it easier for me to experiment with things in an
AIX cross compiler.

Thanks!
