             Bug #: 52239
           Summary: Upgrade GCC Bugzilla to 4.2
    Classification: Unclassified
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: web
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: LpSolit@netscape.net


It's upgrade time again! :)

Or more exactly, we are close from releasing Bugzilla 4.2 final upstream
(currently at 4.2rc2) and it has some valuable security fixes and new features
compared to 4.0:

 http://www.bugzilla.org/releases/4.2/release-notes.html#v42_feat


I blogged about security improvements, and I think it worths reading:


http://lpsolit.wordpress.com/2012/02/01/bugzilla-4-2rc2-4-0-4-3-6-8-and-3-4-14-released/

GCC Bugzilla is currently running 4.0.4, so it has most of the security
improvements mentioned in my post, so no worry about that. :)

If there is something I should be aware of before doing the upgrade to 4.2 (due
to new security restrictions), please let me know. :)


I have no ETA for the final release of 4.2 (still a few blockers to fix first),
so there is no ETA for the upgrade of GCC Bugzilla yet, but I guess this should
happen at the end of this month, or during next month.

@overseers: remind me when you plan to upgrade to Perl 5.10+, please. :)

Confirmed, CCing overseers since there is a question about the perl version.

Bugzilla 4.2 has been released today. But overseers told me that bzr (Bazaar)
cannot be installed on the server because it has a too old version of Python.
As Bugzilla 4.0.x is the last branch to have a CVS mirror of the upstream bzr
repository, I will have to wait for the upgrade of the server before I can
install Bugzilla 4.2 using bzr. Meanwhile, I will keep doing minor upgrades on
the 4.0.x branch.

--- Comment #3 from Frédéric Buclin <LpSolit at netscape dot net> 2012-08-14 18:58:00 UTC ---
Another reason why I cannot simply download the 4.2 tarball and install it till
bzr is available: Bugzilla 4.2 requires MySQL 5.0.15, but the version available
is 4.1.22, a way too old version of MySQL.

@oversees: any news about the migration to the new hardware/software?

We released Bugzilla 4.4rc1 meanwhile, and 4.4rc2 should be released in the
next 2 weeks. 4.4 final will come next.

I saw that the OS has finally been upgraded to RHEL6. This means that it's now
possible to upgrade to Bugzilla 4.4. I won't have time this month, but that's
doable during next month.

That's out of my control. This must be fixed on the SVN side, not the Bugzilla
one.

             Bug #: 57210
           Summary: Using alignas with an union does not compile.
    Classification: Unclassified
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: damien.levac@gmail.com


I have a construct of the form:

template <unsigned int ALIGNMENT>
class foo {
    /* ... */
    private:
        alignas(ALIGNMENT) union bar_ { /* ... */ } bar;
};

which does not compile with the following errors:
    error: 'ALIGNMENT' is not a type
    error: ISO C++ forbids declaration of 'alignas' with no type [-fpermissive]
    error: expected ';' at end of member declaration

The following alternatives have been tried without success:

/* ... */
union alignas(ALIGNMENT) bar_ { /* ... */ } bar;
union bar_ { alignas(ALIGNMENT) int foo; /* ... */ } bar;
/* ... */

With different but equivalent error messages.

Test case 2 for issue 57204

The original test and description are slightly misleading because they could be
interpreted to suggest that the compiler should generate the same optimized
code for the good case and bad case. This was not the intent of providing those
two tests. The two tests may give the same result algorithmically if all
elements of d are non-negative, but the actual operations can be different.
Consider the following:

Good:
k=0: ...
k=1:
  i=0:
    d_ik = d[1]
    j=0: ...
    j=1:
      t = d_ik + d[n+1]
      d[1] = MIN(d[1],t)
    j=2:
      t = d_ik + d[n+2]      <--- This is different
      d[2] = MIN(d[2],t)
    ...

Bad:
k=0: ...
k=1:
  i=0:
    j=0: ...
    j=1:
      t = d[1] + d[n+1]
      d[1] = MIN(d[1],t)
    j=2:
      t = d[1] + d[n+2]      <--- This is different
      d[2] = MIN(d[2],t)
    ...

Attached a second set of tests to more clearly demonstrate the issue. The
following cases result in the same operations, but the compiler still generates
worse code for the bad case than the good case. In the bad case, it once again
generates slower code with auto-vectorization than without auto-vectorization.

New Good:
void foo(float * d, int n)
{
  int i, j, k;
  for (k=0; k<n; ++k) {
    for (i=0; i<n; ++i) {
      for (j=0; j<k; ++j) {
        float t = d[i*n+k] + d[k*n+j];
        d[i*n+j] = (d[i*n+j] < t) ? d[i*n+j] : t;
      }
      for (j=k; j<n; ++j) {
        float t = d[i*n+k] + d[k*n+j];
        d[i*n+j] = (d[i*n+j] < t) ? d[i*n+j] : t;
      }
    }
  }
}

Note that I didn't include the fix from
https://bugzilla.mozilla.org/show_bug.cgi?id=571533 yet as I first want to make
sure that this fix is still needed after the upgrade.

I will need to shut down Bugzilla while I do a backup of the DB, upgrade the
source code and update the DB schema. I will do it tomorrow (Thursday).

That's weird. I can indeed reproduce the problem on GCC Bugzilla, but not on my
local copy of GCC Bugzilla nor in a vanilla 4.4 installation. Investigating!

I spotted a minor size inefficiency in the code:

   0x0000000000400720 <+32>:    jle    0x4007c5 <_Z6write2R6Streamj+197>
   0x0000000000400726 <+38>:    mov    %rdx,%rsi
   0x0000000000400729 <+41>:    test   %r12b,%r12b
...
   0x00000000004007c5 <+197>:    mov    (%rbx),%rsi
   0x00000000004007c8 <+200>:    mov    %rbx,%rdi
   0x00000000004007cb <+203>:    callq  0x4005d0 <_ZN6Stream5WriteEPhS0_>
   0x00000000004007d0 <+208>:    mov    (%rbx),%rdx
   0x00000000004007d3 <+211>:    mov    %rdx,0x8(%rbx)
   0x00000000004007d7 <+215>:    mov    %rdx,%rsi
   0x00000000004007da <+218>:    jmpq   0x400729 <_Z6write2R6Streamj+41>

The mov at +215 would not be needed if the jump went to +38 instead of +41.

            Bug ID: 57250
           Summary: [C++11] std::shared_ptr misses atomic_* support
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: daniel.kruegler at googlemail dot com

Consider this as a reminder bug entry to provide the atomic_* overloads for
std::shared_ptr. A minimal test case could be:

#include <memory>

int main() {
  const std::shared_ptr<int> p;
  bool is_lock_free = std::atomic_is_lock_free(&p);
  std::shared_ptr<int> p2 = std::atomic_load(&p);
  std::shared_ptr<int> p3 = std::atomic_load_explicit(&p,
std::memory_order_seq_cst);
  std::atomic_store(&p2, p);
  std::atomic_store_explicit(&p2, p, std::memory_order_seq_cst);
  std::shared_ptr<int> p4 = std::atomic_exchange(&p2, p);
  p4 = std::atomic_exchange_explicit(&p2, p, std::memory_order_seq_cst);
  bool chk = std::atomic_compare_exchange_weak(&p2, &p3, p);
  chk = std::atomic_compare_exchange_strong(&p2, &p3, p);
  chk = std::atomic_compare_exchange_weak_explicit(&p2, &p3, p,
std::memory_order_seq_cst, std::memory_order_seq_cst);
  chk = std::atomic_compare_exchange_strong_explicit(&p2, &p3, p,
std::memory_order_seq_cst, std::memory_order_seq_cst);
}

Since the update, the Bugzilla favicon is shown,

Created attachment 30132

gcc49-pr57300.patch

We can actually use epilogue_completed, while that is set already a few passes
before peephole2, the only split it runs is on eh_return immediately after
setting it, so it won't split this (and even if it would, it is not a
wrong-code matter, just missed-optimization).  But, generally we then peephole2
this fine if possible (reg is dead), or split4.  Tested:
long long c;

void
foo (int a)
{
  c = a;
}
where the reg is indeed dead to verify.  So is this approach reasonable, at
least for 4.8.1?

Doesn't work here:

$ curl http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52238 2>/dev/null|grep ico

still shows
    <link rel="shortcut icon" href="images/favicon.ico" >
which is still the Bugzilla symbol instead of the GCC symbol:
http://gcc.gnu.org/bugzilla/images/favicon.ico

At the Sourceware site, it shows the correct favicon:
   http://sourceware.org/bugzilla/images/favicon.ico

Did you by chance (only) fix it there?
