[Bug fortran/41827] New: [Cleanup] Remove SET_EXPR_LOCATION in gfc_trans_code
At the end of gfc_trans_code one finds the following:
gfc_set_backend_locus (code-loc);
if (res != NULL_TREE ! IS_EMPTY_STMT (res))
{
if (TREE_CODE (res) != STATEMENT_LIST)
SET_EXPR_LOCATION (res, input_location);
/* Add the new statement to the block. */
gfc_add_expr_to_block (block, res);
}
}
/* Return the finished block. */
return gfc_finish_block (block);
}
In principle the call to SET_EXPR_LOCATION should not be needed here, since the
location should already be set correctly at this point; cf. the discussion in
http://gcc.gnu.org/ml/fortran/2009-10/msg00205.html
and follow-ups. However, this patch

One should find out for which kind of statements the SET_EXPR_LOCATION is
actually needed, and fix those in an appropriate way.

[Bug libstdc++/41792] overloading the address operator confuses the standard containers
--- Comment #2 from jkherciueh at gmx dot net 2009-10-26 09:44 --- (In reply to comment #1) Didn't I reply to this issue already on the mailing list, recently? Anyway, within C++03 the is supposed to not be overloaded, you can take it for example from the lines in the standard about allocator::address. James Kanze (comp.lang.c++) pointed out that it's just a requirement for CopyConstructible. It's in Table 30. Also, about list specifically, when we recently we did a change involving in a member function, provided by LWG chair Howard Hinnant, we carefully reconsidered this issue, and verified that within of C++03 we are fine. As an extenssion, I agree it would make sense to have something like boost::address_of in such cases (whose implementation, as far I remember, it's just *ugly*) Yup, as an extension, it could make sense: The only reason to take the address is in iterator::operator*(), so the source would not be littered with address_of(). Also, in C++0X, one has to provide addressof() anyhow. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41792

It's in Table 30. Thanks for the pointer, I discussed this issue a few times without actually ever reading those lines, I admit. Yup, as an extension, it could make sense: The only reason to take the address is in iterator::operator*(), so the source would not be littered with address_of(). Also, in C++0X, one has to provide addressof() anyhow. Yes, C++0x is different, much better, with the new scoped allocator model, which is still slightly in flux. Just in case you didn't notice already, C++0x will also include answers to 580. unused allocator members, and 635. domain of allocator::address, which Howard filed at the same time of that change to our std::list. And also 431.

[Bug fortran/41829] [OOP] Runtime error with dynamic dispatching

[Bug fortran/41831] New: Bug with management of NaNs
I find that there is a bug with respect to the
management of the NaNs from C to fortran.
This bug happens on Ubuntu 64bits (and not with 32bits).
returnanan.c defines 2 functions
nan = returnanan() : returns a NAN,
void returnanan2(nan) : sets the NAN in the input argument, passed by address.
test.f computes NAN with 3 methods :
#1 : uses returnanan()
#2 : creates NAN with (1-ONE)/(1-ONE)
#3 : uses returnanan2(nan)
This produces the following output :
(returnanan) nan = nan // OK
X #1: 0. // WRONG
X #2: NaN // OK
(returnanan2) nan = nan // OK
X #3: NaN // OK
My conclusion is that there is a problem when the
NAN is passed from the C to the fortran.
I cannot explain the fact that if the address of the
NAN is passed to the C function, it works.
This bug is related to Scilab, see :

[Bug tree-optimization/41834] New: Missed may be uninitialized warning on array reference
Using GCC 4.4.1 and the command on the following test
gcc -O2 -Wall -Wextra
#include stdio.h
int foo (int b)
{
int a[10], c, i;
for (i = 0; i b; i++)
{
a[i] = b;
c = b;
}
if (a[2] == 5 c == 5)
{
printf(hello world\n);
}
return 0;
}
testWarn.c: In function 'foo': testWarn.c:5: warning: 'c' may be used
uninitialized in this function
However, a warning for a[2] being possibly uninitialized is missing.
If I understand right, this should be handled by late warning pass which just
after DCE. Looking at post DCE dump
foo (int b)
{
unsigned int D.1282;
int i;
int c;
int a[10];
_Bool D.1243;
_Bool D.1242;
_Bool D.1241;
int D.1240;
bb 2:
if (b_5(D) 0)
goto bb 3;
else
goto bb 4;
bb 3:
# i_21 = PHI 0(2), i_8(3)
D.1282_25 = (unsigned int) i_21;
MEM[base: a, index: D.1282_25, step: 4] = b_5(D);
i_8 = i_21 + 1;
if (i_8 != b_5(D))
goto bb 3;
else
goto bb 4;
bb 4:
# c_17 = PHI b_5(D)(3), c_4(D)(2)
D.1240_9 = a[2];
D.1241_10 = D.1240_9 == 5;
D.1242_11 = c_17 == 5;
D.1243_12 = D.1242_11 D.1241_10;
if (D.1243_12 != 0)
goto bb 5;
else
goto bb 6;
bb 5:
__builtin_puts (hello world[0]);
bb 6:
return 0;
}
there is a path to bb 4, which does not initialize a. Why do we not generate a
warning? Is it due a missing PHI for a?

My conclusion is that there is a problem when the
NAN is passed from the C to the fortran.
That's not my conclusion. :)
double C2F(returnanan)(void)
{
(snip)
PROGRAM test
DATA ONE/1.0D0/
DOUBLE PRECISION X
X = returnanan()
Add 'IMPLICIT NONE' to your code. The Fortran code is
expecting has implicitly typed returnanan() as REAL.
Your C code has declared returnanan() to return a double.
C's double is not the same thing as Fortran's REAL.

[Bug c++/41838] Incorrect dereferencing pointer 'anonymous' does break strict-aliasing rules
--- Comment #2 from pinskia at gcc dot gnu dot org 2009-10-26 23:42 --- There's no aliasing through the void*. This is not true. In fact aliasing is not about what the type of the pointers are but what the dynamic type of what the pointer points to and the access type. But that is not the issue here though. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41838

Can I please know why g++4.2.3 is behaving differently that g++ 3.3.3?
According to C++, we can declare the pointer(s) of abstract base class. But why
is g++ 4.2.3 compiler not allowing to even declare these pointers?
Is this a bug in g++4.2.3?
In which release of g++, this bug is fixed?
There are many other such deviations we noticed in this compiler from the
normal C++ principles.
Should we not use g++ 4.2.3? Which is the most stable version in g++ 4.x.x
series?
Please help.
