[Bug libstdc++/45549] merge is_iterator into iterator_traits

> __is_iterator can be useful anyway,

Of course, they should use the same helper classes but they can coexist,
although the 2 current uses of is_iterator would disappear. I was personally in
favor of having is_iterator in the standard...

> Anyway, are you sure that, given the current wording in C++0x, such
> iterator_traits is strictly conforming?

Howard seems to think so. The first paragraph of [iterator.traits] is good, the
second one not so good (but it could be argued that the definition is provided
for exposition, that it doesn't have to be copied verbatim to every
implementation). It doesn't seem less conforming than what is used for
next/prev.

But then in some sense it is an extension, as it lets not strictly conforming
code work (but doesn't break any conforming code). Which is why I am asking
about an opinion on a possible enhancement, not calling it a bug.

Well, I think we are comparing two changes of very different impact and size.
In the case of next / prev we have two functions, completely new in C++0x,
getting a bit of constraining in the return type, no additional defaulted
template parameters, only constraining in the return type: I would argue tha,
in general, the way we are living the post-concepts era, this is more or less
something the user looking inside headers of C++ library implementations is
going to find in *many* more places than those where the Standard explicitly
talks about "does not participate to overload resolution". I can also add that
this very thing makes me a little nervous, but I didn't raise the issue
explicitly anywhere, thus... Anyway, in the other case, we are talking about
changing a fundamental building block of the library. Certainly we would do
that only in C++0x mode, agreed, still we are diverging more from C++03 in an
area where the Standard is *not* diverging at all: as far as I can see, either
we could use a defaulted template parameter with the enable_if on __is_iterator
for the default; or we could create a small hierarchy, without enable_if. This
is not something I would deliver for C++03 too, after so many years with a
straightforward implementation, definitely not. Do you have in mind a simpler
way to implement the "smart" iterator_traits?

[Bug target/45483] gcc-4.4.3: probably wrong optimization options chosen by "-march=native"

[pacho at condmat1 dot ciencias dot uniovi dot es]

--- Comment #6 from pacho at condmat1 dot ciencias dot uniovi dot es  
2010-09-06 10:45 ---
This is what I get with gcc-4.5.1:
root   651  0.0  0.1  13080  1780 tty1 S+   19:18   0:00

 - --param l2-cache-size=2048 -mtune=generic -quiet -dumpbase -
 - -- -auxbase-strip /dev/null -o /tmp/cc3udN3F.s

Then, looks like:
1. It's still using -mtune=generic
2. It now uses "-march=pentium-m" instead of "presscott" :-/
3. It doesn't seem to detect "sse3" 

Thanks for your help :-)

The reason is obvious: The configure-script just appends '-lgmpxx' to @ppllibs@
without any gmp library search path.

For those of you who stumbled over this bug report by utilizing your favourite
search engine:
A quick fix is to give
--with-ppl=" -L/lib"
to configure.

BTW: On systems with a shared libppl, libgmpxx is not needed as it is pulled in
via DT_NEEDED.

I completely agree here. After the removal of concepts, the library is in need
of more concept-related work in the standard, it shouldn't be up to the
implementers.

Ok. It seemed safe enough to me (especially since some other implementations do
it), so I thought I should ask.

> Do you have in mind a simpler
> way to implement the "smart" iterator_traits?

No, I was going with the small hierarchy (ie keep the partial specializations
for pointers, and have the generic implementation derive from helper::value> where helper is empty by default and has a
partial specialization for T,true that contains 5 typedefs). It looked like the
safest option.

Feel free to close the bug if you think it is a bad idea.

Nice that we agree on many points. Anyway, my plan would be (I cannot resist ;)

Just to make sure, does that mean you are writing the prototype, or do you want

[Bug bootstrap/45556] New: Add PPL and CLooG-PPL source to gcc source tree for build

[tom dot browder at gmail dot com]

As of now, gcc builds with gmp, mpfr, and mpc source directories placed in the
gcc tree by the user.  Adding the other two main prerequisites into the tree
for full gcc features would be a win for users.  The inter-dependence of the
configuration options between the latter two and gmp, mpfr, and mpc makes it
difficult for a user to build all successfully without trial and error.  An
explicitly versioned set of the five sources known to work for a given version
of gcc to be downloaded with a helper script (like the one by Andrew Haley:
download_prerequisites.sh) would be very helpful and ease debugging and help
for all.

Testsuite results for the PR36502v9.patch are shown in
http://gcc.gnu.org/ml/gcc-testresults/2010-09/msg00537.html. The compiler ICEs
shown for gfortran.dg/backspace_1.f, gfortran.dg/record_marker_2.f,
gfortran.dg/graphite/pr42393-1.f90 libgomp.fortran/appendix-a/a.16.1.f90,
libgomp.fortran/omp_atomic2.f90, libgomp.graphite/force-parallel-3.c,
libgomp.graphite/force-parallel-9.c and 25_algorithms/heap/moveable.cc
shouldn't be due to my patch as the identical patch (except for test cases
corrections) was tested in
http://gcc.gnu.org/ml/gcc-testresults/2010-09/msg00168.html and didn't show
them. While I don't see these in other reported i386-apple-darwin10
testresults, those aren't using --enable-checking=yes. I will rebuild gcc trunk
without PR36502v9.patch, reconfirm those ICEs and file PRs against them
separately.

[Bug c/45559] New: [4.4 regression] wrong conversion from unsigned int/long to float

[zimmerma+gcc at loria dot fr]

With the following program:

#include 

int
main()
{
  unsigned int t = 254733465;
  float f;
  f = (float) t;
  printf ("t=%u f=%.0f\n", t, f);
}

I get with gcc 4.3 the expected result:

t=254733465 f=254733472

but with gcc 4.4.5:

t=254733465 f=482062944

which is clearly wrong.

Note: this was obtained on smetana.debian.org with
gcc 4.4.5 20100824 (prerelease) (Debian 4.4.4-11)

Note 2: this bug makes GMP-ECM fail:

Looks like it's some mixup of ""/"no"/"dpd" somewhere...
It looks like the dfp.m4 patch is wrong, enabling dfp half-way, such that the
parser and preprocessor doesn't see that it's not supported, but the target
still isn't "dfp" as far as the test-suite is concerned (and it shouldn't):

Unfortunately, even with your patch the mips-sgi-irix6.5 Ada bootstrap
is still broken.

I just noticed that even in the complete absence of reload inheritance, the
allocate_reload_reg routine performs free_for_value_p checks, and therefore
implicitly takes reload ordering into account.  This seems to imply that even
if we'd do merge_assigned_reloads only if no inheritance has taken place, we'd
still have a problem.

Does anybody have any idea how much merge_assigned_reloads actually contributes
to performance on i386, in particular now that we have a bit more post-reload
optimizers that potentially clear up duplicate code of the type generated by
unmerged reloads?

Nice. Just to confirm, that's indeed what I had in mind, except that I was
going to rename __is_iterator_helper to __has_iterator_category and move
"||is_pointer" from the helper to __is_iterator (and then use
__has_iterator_category for __iterator_traits). But it is equivalent.

Now to the hardest part: deciding whether to apply it ;-)

More failures:

use iso_fortran_env
integer :: i
print *, shape(real_kinds(1))  ! should be rejected (scalar)
i = real_kinds(1)  ! ICE
end

Thus, the FE has problems if one takes a REF of an EXPR_ARRAY, i.e. the shape
does not get updated.

Patch to address IPA-CP parameter removal issues

This patch makes IPA-CP to refrain from modifying a function when it
sees a any type attributes.  It fixes the test case.  I do not expect
it to cause any problems elsewhere but I have not yet bootstrapped or
tested it (I have just scheduled both for tonight).

As far as I understand it there is already a test in our testsuite
that fails (with the patch from comment #7 applied) and so I am not
going to add an extra one.

I think it's best to check this in separately and I will submit it for
approval tomorrow if there are no unforeseen problems.

In a way that's unfortunate: Both "fn attr" and argument removal are
optimization options.

FAAD developers don't answer my e-mails, so what I can do? Resort to compile
FAAD library using a specially compiled GCC? What about other less experienced

There is no full port of the Ada compiler to this platform in the FSF tree.
You can only build a 64-bit Ada compiler with the unpatched sources.

Bisection identified r163383, Bernd's 4-insn combine patch, as the cause for
this regression.  However, it got fixed today by r163917, Andreas Krebbel's fix
for an s390x regression from r163383.
