[Bug c++/80916] New: Spurious "declared 'static' but never defined" warning

[davmac at davmac dot org]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80916

Bug ID: 80916
   Summary: Spurious "declared 'static' but never defined" warning
   Product: gcc
   Version: 7.1.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: c++
  Assignee: unassigned at gcc dot gnu.org
  Reporter: davmac at davmac dot org
  Target Milestone: ---

The following code (reduced via creduce) gives a warning, when compiled with:
g++ -std=c++11 -Os -Wall -Wno-invalid-offsetof -c dinit-warn.cc

dinit-warn.cc:20:40: warning: 'void b::i< 
>::dispatch(void*) [with  = {anonymous}::l]' declared
'static' but never defined [-Wunused-function]
 template  class i : j { void dispatch(void *); };
^~~~

However, the highlighted function, "dispatch", is not declared 'static' (and
indeed nothing in the code is declared static). Occurs at -Os and -O2, -O3, not
at -O1/-O0.

--- begin ---
class a;
namespace b {
template  class i;
class j {
  friend a;
  virtual void dispatch(void *);
};
}
class a {
  using d = b::j;

public:
  template  using c = b::i;
  void f() {
d *k = nullptr;
k->dispatch(this);
  }
};
namespace b {
template  class i : j { void dispatch(void *); };
}
using g = a;
g h;
namespace {
class l : g::c {};
}
void m() { h.f(); }

I can't seem to get gcc-go to work in my builds of GCC, and I don't understand
why. Here's my build configuration:

Whenever I run the gcc-provided 'go' binary, I just get this:

$ go.gcc
fatal error: DWARF underflow in .debug_info at 4

runtime stack:
fatal error: DWARF underflow in .debug_info at 4
panic during panic

runtime stack:
Segmentation fault (core dumped)
$


Assuming my GCC build process is doing what it should, the go.gcc binary should
have debug info and not be stripped, and 'file' appears to agree that's the
case:

$ file /usr/bin/go.gcc
/usr/bin/go.gcc: ELF 64-bit LSB executable, x86-64, version 1 (SYSV),
dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux
2.6.32, BuildID[sha1]=4467591638a8ccaebbab3384129ec221295ad6a9, not stripped,
with debug_info


But based on the "DWARF underflow" messages, I guess the debug information in
the binary is somehow broken?

We now have the function check_conjg_transpose_variable in frontend-passes.c,
which we could use for detecting and counting transpose and conjg.

Hmm... looks like we could do something with that in
gfc_conv_intrinsic_funcall.

[nathan at gcc dot gnu.org]

--- Comment #6 from Nathan Sidwell  ---
I have a small reproducer, regardless of bitsize:

extern int meminfo ();
struct meminfo {};

void frob ()
{
  meminf ();
}

stat hack when the struct decl is last.  It looks like a patch I have on the
modules branch is not as orthogonal to this as I thought.

Good, so no point in me trying the 64-bit route.

No worries: same here, and I can always revert the patch locally until
the bug is resolved.

yes, must be something with a 32-bit target.  I can reproduce it on x86_64
linux host targeting either i386-linux or i386-solaris. 

We have a TYPE_DECL whose TREE_CHAIN points to itself.  So when the spelling
corrector iterates over the decls in a namespace it gets stuck at that point.

It's end of day here, so don't expect more progress until tomorrow.

Maybe it's a 64-bit vs. 32-bit thing then?  I could try
amd64-pc-solaris2.12 and sparcv9-sun-solaris2.12 bootstraps with your

--- Comment #1 from Nathan Sidwell  ---
My money's on:
Stat hack representation
* name-lookup.c (STAT_HACK_P, STAT_TYPE, STAT_DECL,
MAYBE_STAT_DECL, MAYBE_STAT_TYPE): New.
(stat_hack): New.
(find_namespace_binding): Replace with ...
(find_namespace_slot): ... this.
(find_namespace_value): New.
(name_lookup::search_namespace_only,
name_lookup::adl_namespace_only): Adjust.
(update_binding): Add SLOT parameter, adjust.
(check_local_shadow): Use find_namespace_value.
(set_local_extern_decl_linkage): Likewise.
(do_pushdecl): Adjust for namespace slot.
(push_local_binding): Assert not a namespace binding.
(check_for_out_of_scope_variable): Use find_namespace_value.
(set_identifier_type_value_with_scope): Likewise.
(get_namespace_binding): Likewise.
(set_namespace_binding): Delete.
(set_global_binding): Directly update the binding.
(finish_namespace_using_decl): Likewise.
(lookup_type_scope_1): Use find_namespace_slot and update.
(do_push_nested_namespace): Use find_namespace_value.

But x86_64-linux is not being affected in the way you describe.  The backtrace
is something borking in the spelling correcting stuff.

   Summary: [8 regression] Infinite loop in cc1plus with stat hack
patch
   Product: gcc
   Version: 8.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3

preprocessed input

Between 20170528 (r248544) and 20170529 (r248574), mainline bootstrap on both
Solaris/x86 and Solaris/SPARC hangs in stage2 with cc1plus compiling a
configure
test for basename.  The compilation hasn't finished even after 50 minutes while
it should take only seconds, of course.

The problem boils down to

$ cc1plus -fpreprocessed conftest.ii -quiet -mcpu=v9 -o conftest.s

with the attached conftest.ii.

A stacktrace looks like

[-Wundeclared-selector]
performSelector:@selector(sharedKeyBindingManager)];
^~~

2. Better location info: the caret points to the beginning of the line instead
of the actual selector that is undeclared:

macappkit.m:2016:7: warning: undeclared selector ‘setQuoteBinding:’
   [keyBindingManager performSelector:@selector(setQuoteBinding:)
   ^

should point to 'setQuoteBinding:' instead.

3. '-Wundeclared-selector' ignores -ftrack-macro-expansion. Take for example:

macappkit.m: In function ‘-[EmacsController
handleQueuedNSEventsWithHoldingQuitIn:]’:
macappkit.m:1869:8: warning: undeclared selector ‘dummy’
MOUSE_TRACKING_RESET();
^~~~

MOUSE_TRACKING_RESET is a macro that expands to:

#define MOUSE_TRACKING_RESET()  \
  [self setTrackingObject:nil andResumeSelector:@selector(dummy)]

on line 1735 of this file. I would expect the warning to point inside the
definition of this macro, instead of pointing where it is used.

The file I am compiling, macappkit.m, is from YAMAMOTO Mitsuharu's Mac port of
Emacs. Full command line is:

This potentially caused errors while compiling Clang 3.9 in C++1z mode.

See Richard Smith comments on
http://lists.llvm.org/pipermail/cfe-commits/Week-of-Mon-20170522/193826.html

Quote:
"""
This is wrong. We have a "public:" on the previous line! But I think this
is just GCC's diagnostic being screwed up and what it's trying to say is
that it selected a deleted function.

But this function is the wrong overload resolution result; the operator
std::string from the base class should be selected.

[Bug gcov-profile/80911] gcov failed: gcno corrupted

I have not yet been able to reproduce the problem in a standalone build and
test (and I need to keep the build I encountered this in undisturbed). So it's
not easy for me to try this out atm.


OTOH, I think I managed to pin-point the problem with valgrind when running
gcov:
...
==23606== Conditional jump or move depends on uninitialised value(s)
==23606==at 0x405E70: read_graph_file() (gcov.c:1391)
==23606==by 0x404BD5: process_file(char const*) (gcov.c:914)
==23606==by 0x40454C: main (gcov.c:666)
==23606== 
gcov-1.gcno:corrupted
gcov-1.gcda:profile mismatch for 'main'
...

gcov.c:1391:
...
  1388unsigned mark_catches = 0;
  1389struct arc_info *arc;
  1390  
  1391if (src >= fn->blocks.size () || fn->blocks[src].succ)
  1392  goto corrupt;
  1393  
  1394while (num_dests--)
...

So, AFAIU, the immediate problem is that the corruption test reads
uninitialized memory (which I think confirms your analysis).

Hi,

There's the problem, for the file you sent me, I don't see the same:

$ ./gcov-dump /home/marxin/Programming/testcases/pr80911/gcov-1.gcno

while for my gcno file created I see the same what you can see:

$ ./gcov-dump gcov-1.gcno
gcov-1.gcno:note:magic `gcno':version `A80e'

You file is also much smaller:
marxin@marxinbox:~/Programming/gcc/objdir/gcc> l
/home/marxin/Programming/testcases/pr80911/gcov-1.gcno
-rw-r--r-- 1 marxin users 335 May 29 11:57
/home/marxin/Programming/testcases/pr80911/gcov-1.gcno
marxin@marxinbox:~/Programming/gcc/objdir/gcc> l gcov-1.gcno
-rw-r--r-- 1 marxin users 1056 May 29 11:51 gcov-1.gcno

That said can you please verify gcov --version and gcov-dump --version.
The gcno file should be flushed and closed in gcov_close function. Can you
please take a look?

Thanks,
Martin

Can't confirm that, running trunk@248556 works fine for me.
Utilizing valgrind also does not help.

Can you please run a single test manually:

$ gcc --coverage gcov-1.c
$ ./a.out
$ gcov gcov-1.c

And you can also test:
$ gcov-dump gcov-1.gcno
