The issue is indeed about use of reinterpret_cast in a constexpr method. The consensus, according to bug 55039, is that this should not be supported. There is also a lot of mention of 'the other PR'. Am I missing something, or is GCC being non-strict by still supporting this? Is there a stricter mode where this and other extensions are not available (for writing portable code)?

I can understand that this is ok behavior for C, but to have to
EXPLICITLY ASK typesafe language like C++ to inform me if function
WITH RETURN TYPE does not return anything ?
If this is not bug why shouldn't we make
int n;
n =;
printf("%d",n);
to be legal code, compiler should simply assign whatever it wants. Right ?
Could anyone explain what for should missing return on typical C++ function
be useful at all ?
Not to mention probability that it has been forgotten by mistake.
-Wreturn-type should be set by default.

{

unsigned int i;
for (i = 0; i < c; ++i)

No, because that's not even legal syntax, so that's a completely different
case.

OK, so let's change the report to say that then.
In general though, please don't report bugs claiming there are no warnings if
you haven't even tried -Wall, there's a notice when you report a bug asking you
to check that.
Reduced example:
struct A { int i; };
A f()
{
A a = { 0 };
// missing return
}
int main()
{
A a = f();
return a.i;
}
[Bug target/54791] AIX-only: Constructors are not called in main program.
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54791 --- Comment #7 from David Edelsohn 2012-11-03 13:48:46 UTC --- The New York area has experienced a major natural disaster. I am located near NYC. GCC support is provided by volunteers. Repeatedly resending your message will not elicit a faster response. AIX uses the XCOFF file format, not ELF. The object files do not contain .ctor or .init sections to define constructors. The GCC collect2 wrapper scans object files for constructors and creates a function to call them. If the constructors are inlined, the symbols might not appear when the object files are scanned, preventing them from being included in the list of constructors to call.

[Bug libstdc++/54075] [4.7.1] unordered_map insert 3x slower than 4.6.2
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54075
--- Comment #33 from François Dumont 2012-11-03
15:28:30 UTC ---
I fear that this performance issue is a normal drawback of the major
enhancement for PR 41975. Before this evolution the hashtable data model was
like a std::vector. During the insert operation it was easy
to find out if the inserted element was already in the targetted bucket by
simply checking for equality with each element of the bucket forwward_list. The
code was something like:
for (auto it = bucket.begin(); it != bucket.end(); ++it)
if (comp(*it, element))
// The element already exists
return false;
// Ok, no equivalent element
return true;
After the evolution the data model became a combination of a
std::forward_list containing all elements and a
std::vector::iterator> representing buckets. Now to check
if an element is already in a bucket we still need to compare for equality with
each element of the bucket but the element of the bucket are harder to
identified. There is no more bucket end so we must also check that the element
we are about to compare is still in the bucket. The code became something like:
// Pre: bucket not empty.
for (auto it = buckets[n];)
{
if (comp(*it, element))
// The element already exists
return false;
++it;
if (it == end() || bucket(it) != n)
// We are not in bucket n anymore
return false;
}
// Ok, no equivalent element
return true;
The new design helps to iterate through the container because even if it is
almost empty we simply need to iterate within the forward_list. In the previous
implementation we needed to iterate within a bucket forward_list and then jump
above all empty buckets which could be very expensive. Try to run
testsuite/performance/23_containers/insert_erase/41975.cc, you can easily tweak
it to make it run with the tr1 implementation and you will notice the
difference. This test also show the insert overhead even if with a perfect
hasher like the one use in this test the impact is very limited.
To make bucket(it) not too expensive the new implementation caches most of the
time the hash code which explain the additional memory. You can try to ask for
it not to be cache but you might have to qualified your hasher with noexcept,
static assertions will tell you so.
So for the moment I can see a way to restore tr1 insert performance without
impacting erase performance. In my opinion, a Standard implementation needs to
behave correctly in all use cases and not to be perform very well in one use
case but very bad in an other.

I did it because I got delivery failures on the first 4 mails.) So just to be 100% sure on this: If I want to be sure all my constructors are called I should not have any of them inlined. Correct ? What about if I have a constructor body/implementation inside a class declaration ? Does the compiler inline that as well? I guess it might. So how do you see this case. Is it not a bug? I mean I am expecting my constructors to be called and they are not. Do you know a easy way to solve this without modifying all my constructors ? (any compiler options perhaps, ..using __attribute__((constructor)) ) ? PS: If I want to send you an attachment in a mail what format should it be ? txt, doc ?

I am located near NYC. GCC support is provided by volunteers. Repeatedly resending your message will not elicit a faster response. AIX uses the XCOFF file format, not ELF. The object files do not contain .ctor or .init sections to define constructors. The GCC collect2 wrapper scans object files for constructors and creates a function to call them. If the constructors are inlined, the symbols might not appear when the object files are scanned, preventing them from being included in the list of constructors to call.

Correct ? > What about if I have a constructor body/implementation inside a class > declaration ? Does the compiler inline that as well? I guess it might. I am not positive that inlining is the problem, but that seems like a good hypothesis. collect2 scans object files looking for constructors by name, e.g., GLOBAL__I_ You can look at the global symbols using $ nm -BCpg .o If the constructors are visible when NOT inlined and disappear when they are inlined, that is the problem. If "nm" cannot see them, the mechanism for creating the list of constructors (and destructors) cannot see them either. > So how do you see this case. Is it not a bug? I mean I am expecting my > constructors to be called and they are not. > Do you know a easy way to solve this without modifying all my constructors ? > (any compiler options perhaps, ..using __attribute__((constructor)) ) ? The methods already are constructors. Additional attributes will not make a difference. If you can create a small, self-contained testcase with a constructor that works or does not work depending on inlined, I can look. I am not sure how inlined constructors are recorded in ELF files. This sounds like a bug, but it will take some investigation to figure out how difficult it is to fix given the behavior of AIX and GCC. Inlined constructors may not be a practical option on AIX. Also, please use the GCC Bugzilla interface for comments and attaching testcases, not email replies. There probably is a way to add attachments using email, but I do not know how and Bugzilla is much more useful without all of the email history already present in the comment history.

The problem is that we do in module.c's gfc_use_modules: gfc_use_module (module_list); if (module_list->intrinsic) free_rename (module_list->rename); But then in trans-decl.c's gfc_trans_use_stmts: for (rent = use_stmt->rename; rent; rent = rent->next) While freeing the memory is probably fine for build-in intrinsic modules like ISO_Fortran_env and ISO_C_Binding; however, doing so for intrinsic modules which are loaded for a file is wrong.

Unfortunately, -v -save-temps doesn't save the java source from a list input. So far, I've only seen this with jc1. I imagine this is because the input is huge.

Well, I haven't looked into this issue in detail, but, it looks like everyone
is about the same speed if you put a foo.{reserve or rehash}(n) before the
inserts.
Unfortunately, it doesn't look as simple as the new impl calling for a rehash
more often than the old, cause it's not. So, I don't know if the slowness is
because rehash is now a lot slower, or if insert is slower but only if there
aren't a huge number of empty buckets.
I'll also note that libc++'s implementation (seen here:
http://llvm.org/svn/llvm-project/libcxx/trunk/) appears to be getting the same
speed as the old libstdc++ implementation, while appearing to have
approximately the same bucket datastructure as the new libstdc++
implementation. That says to me that it should be *possible* somehow to make
the new version fast.
