Hello,

would it be possible for you to check whether this problem still occurs on gcc 3.3? This should be 
checkable by cross compiler, but unfortunately, binutils for hp-ux has issues cross-compiling... 
Thanks,

Dara

Subject: Re:  [HP-UX] typeinfo not generated correctly when #pragmas are involved

Hi all bug trackers,

  Sorry for the delay, I just didn't find any time for testing this issue. 
Unfortunately we have switched to AIX-5.1 in the meanwhile, so I can oonly 
provide a test for this platform with the given example:

$ gcc -c LS.cc && nm LS.o | c++filt | grep typeinfo
0000000000000368 D typeinfo for LS
                 U typeinfo name for LS
$ gcc -v
Reading specs from /usr/local/lib/gcc-lib/powerpc-ibm-aix5.1.0.0/3.3/specs
Configured with: ../gcc-3.3/configure --disable-nls
Thread model: aix
gcc version 3.3
$

So, its the same again for gcc-3.3 under AIX-5.1 (I also did not discover weak 
symbols on this platform). The typeinfo name symbol is still undefined.

Hopefully, I will be a little faster the next time in giving feedback.

   Wolfgang

There is no testcase reduction yet, and regression analysys. Can anybody able 
to reproduce the bug work out a reduced testcase and check if it's a regression?

Wolfgang, to ease the work, would you please report what the expected output of 
nm should be?

Pay a developer? gcc does not come with any guarantee that we fix bugs 
that are found. We try to, but our highest priority is to fix regressions 
and if your priorities are different you may be willing to pay someone 
to do what you need.

OK, now I know, what's expected from me as a bug reporter. I was just 
wondering, because IMHO this bug seemed to be a simple thing to fix to me.  
But I might be wrong, pleae dont't shout on me, I'm just an ordinary gcc-user 
since 2.6.0, I don't have any experience in compiler programming and I *relly* 
appreciate the work on the gcc developers. This the very first occasion I 
encountered a gcc regression, that's why I' d like to conribute. 
So I will reduce the testcase and confirm, that this is a regression w.r.t. to 
gcc-2.95, because with gcc-2.95 all my programs using #prgama interface linked 
fine under AIX-4.3, while they refused to link starting with gcc-3.2. (I did 
not use gcc-3.{0,1}.x).

Sorry if I sounded rude -- it is just a fact that we are developer starved 
and that we need to focus on what our priorities are. That's why we don't 
make promises as to when a bug is going to be fixed. You can increase your 
chances of a bug getting fixed by paying someone to do it, though. Another 
way is to provide as small a testcase as possible and/or show that this 
is a regression.

Ok, unfortunately I was unable to contruct a simpler test case than the 
original poster. However, I'd say that his testcase LS.tar.gz is already quite 
minimal. 
 
I revisited this test case on my AIX-5.1.0.0 machine using gcc-3.3 and snipped 
the assembler listing of the typeinfo instance of class LS, which has been 
emitted by gcc -s. 
 
The first version is the original example of the poster, which includes a 
std::vector<int> member in class LM. 
 
So summing up, I would decalre this bug a regression against gcc-2.95, with me 
failing to contruct an example without std::vector. I tried to replace 
std::vector with a simple minimal template class but failed to reproduce the 
bug. 
 
TIA to anyone who could assist in solving this problem. 
 
------------AIX assembler listing--------------- 
_ZTI2LS: 
        .long   _ZTVN10__cxxabiv117__class_type_infoE+8 
        .long   _ZTS2LS[RW] 
        .align 2 
        .globl _GLOBAL__F__ZN2LSC2Ev 
_GLOBAL__F__ZN2LSC2Ev: 
----------end of AIX assembler listing--------------- 
 
Here the typeinfo instance (_ZTI2LS) refers the typeinfo name (a symbol which 
should carry the char pointer to the type name, which is "2LS" in this case), 
but this symbol is never generated, which causes the linker error 
 
unresolved symbol 'typeinfo name class xxxx' 
 
for more complex programs, which involve templates and #pragma interface/
#pragma implementation. 
 
As the original poster suggested, I replaced the std::vector<int> by a simple 
int and snipped the assemvbler listing of the generated typeinfo instance. 
 
------------AIX assembler listing--------------- 
_ZTI2LS: 
        .long   _ZTVN10__cxxabiv117__class_type_infoE+8 
        .long   _ZTS2LS 
        .csect _LS.rw_cc[RO],3 
        .align 2 
_ZTS2LS: 
        .byte "2LS" 
        .byte 0 
        .csect .data[RW],3 
        .align 2 
        .globl _GLOBAL__F__ZN2LSC2Ev 
_GLOBAL__F__ZN2LSC2Ev: 
----------end of AIX assembler listing--------------- 
 
Here, the typeinfo correctly refers the generated typeinfo name _ZTS2LS, which 
contains the string "2LS" as expected. 
 
Unfortunately, I don't have a gcc-2.95 installation on a non-wek architecture 
around, but I definitely compiled and linked more complex programs, which show 
the above mentioned linker error, successfully using gcc-2.95 under AIX-4.3.

The testcase is really small (except for the use of the <vector> 
header file, of course). I don't have such a machine, but enough 
people have reproduced it already, so let's mark it as a regression 
and assign a milestone. 
 
Anyone wanting to try present gcc CVS on this?
