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.

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.

Maybe you could refuse to do the update if nobody helps about that. Kidding ;)

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).

I have patches the daily tester with those two patches so we see where we stand
with these improvements...

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:

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

Component: libstdc++

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);

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?
