[Bug c++/40256] New: Explicit function template call doesn't trigger Koenig lookup when it should
14.8.1/6 says:
But when a function template with explicit template arguments is used, the
call does not have the correct syntactic form unless there is a function
template with that name visible at the point of the call. If no such name is
visible, the call is not syntactically well-formed and argument-dependent
lookup does not apply. If some such name is visible, argument dependent lookup
applies and additional function templates may be found in other namespaces.
Then the following example is given, which doesn't compile on GCC-4.3.3:
namespace A {
struct B { };
templateint X void f(B);
}
namespace C {
templateclass T void f(T t);
}
void g(A::B b) {
// stripping out ill-formed cases
using C::f;
f3(b);// well-formed because C::f is visible; then
// A::f is found by argument dependent lookup
}
g++ doesn't compile it, stating:
teste.cpp: In function 'void g(A::B)':
teste.cpp:12: error: no matching function for call to 'f(A::B)'
I haven't tested with 4.4, nor have found a similar bug.

[Bug rtl-optimization/40101] [4.5 Regression] 200.sixtrack ICEs in get_seqno_by_preds, at sel-sched-ir.c:3752
--- Comment #3 from abel at gcc dot gnu dot org 2009-05-26 12:19 ---
I have further looked at seqno handling, and it seems that we can't rip it off
without changing the region walking logic pretty much. Seqnos are computed in
such a way that they mark the stage (the number of iteration of scheduling
loop) on which a parallel group of insns has been scheduled. That is, if all
insns scheduled within the first iteration on fences will get #1, all insns
scheduled within the second iteration will get #2, this will be pretty much
equivalent.
Walking from higher to lower seqnos is prohibited, but not only to mark the
dynamic back-edge, but to forbid moving insns from earlier scheduling
iterations to later ones. E.g., when pipelining, we can move insns from
stage #2 to #0 (yet unscheduled code), possibly through insns from stage #1,
but we cannot move insns from stage #1 to #0 through insns belonging to stage
#2.
This logic is modeled by existing seqnos, so we cannot rip seqnos off without
changing the logic. We can simplify it very slightly by making seqnos to be
plain iteration numbers like described above, but that would not allow removing
any code as I hoped. We can also change this logic so that any movements from
scheduled to unscheduled code is possible for pipelining, but that would
require much more work and some tuning (I would probably try that later, but
not for this bug).
Thus, I would fix just the bug for now. The fix is quite simple. In the
situations like in the testcase, no positive seqnos around the bookkeeping insn
means that the fences will not be able to get to it. This normally happens
during pipelining, though quite rare, so we have a code for this that would
pick up unscheduled bookkeeping and schedule it afterwards. This logic will
deal with the test case, too. We just need to assign pretty much arbitrary
positive seqno in this case.
So the following patch fixes the test case (it passes all SPECs) and bootstraps
on ia64 with sel-sched enabled at -O2, testing is in progress. I will post it
to gcc-patches if the testing will look fine.

The following patch to gfc_match_nullify fixes it; however, I think one should
additionally add
gfc_free_expr (new_st.expr1);
new_st.expr1 = NULL;
gfc_free_expr (new_st.expr2);
new_st.expr2 = NULL;
to prevent a memory leak.
AFAICT, there is no leak.

{

The last gfc_free(e) should prevent a leak.

--- Comment #4 from burnus at gcc dot gnu dot org 2009-05-26 19:29 --- s/main_program/is_main_program/ CLOSE as WONTFIX. As Andrew pointed out, there are a couple of issues using static memory: 1. The middle end does not optimize static variables that well as it does not know about non-recursive procedures 2. Marking loop variables etc. as static does not work well in the context of OpenMP's private. This problem can be reduced by using a certain threshold (as currently done for local variables), but it always exists 3. Given all the trouble, it is unlikely that a real-world program only has a too large array in the main program (which can be cured by this patch); more likely is that further large arrays exists in subroutines etc. For those this patch won't help, but ulimit -s unlimited does. 4. This seems to be a relatively rarely reported problem; general stack limit problems are more common, though. - CLOSE -- burnus at gcc dot gnu dot org changed: What|Removed |Added Status|NEW |RESOLVED Resolution||WONTFIX http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34053

[Bug libstdc++/40263] New: random unform real distro: tr1 vs c++0x
Having some problems porting some code between C++0x and TR1. The C++0x version
works as expected, but the TR1 uniform_real distribution seems to be returning
elements outside the given range.
And example:
#include string
#include iostream
#ifdef __GXX_EXPERIMENTAL_CXX0X__
# include functional
# include random
#else
# include tr1/functional
# include tr1/random
#endif
#ifdef __GXX_EXPERIMENTAL_CXX0X__
typedef std::uniform_real_distributiondouble distribution_type;
typedef std::mt19937engine_type;
#else
typedef std::tr1::uniform_realdouble distribution_type;
typedef std::tr1::mt19937 engine_type;
#endif
double
generate()
{
const distribution_type distribution(0, 1);
static engine_type engine;
#ifdef __GXX_EXPERIMENTAL_CXX0X__
static auto generator = std::bind(distribution, engine);
#else
typedef std::tr1::_Binddistribution_type(engine_type) __result_type;
static __result_type generator = std::tr1::bind(distribution, engine);
#endif
double random = generator();
if (random distribution.min() || random distribution.max())
{
std::string __s(throw_allocator::throw_conditionally);
__s += \n;
__s += random number generated is: ;
char buf[40];
__builtin_sprintf(buf, %f, random);
__s += buf;
std::__throw_out_of_range(__s.c_str());
}
else
std::cout random std::endl;
return random;
}
int main()
{
for (int i(0); i 50; ++i)
std::cout generate() std::endl;
return 0;
}
Gives me this for C++03:
%./a.out
terminate called after throwing an instance of 'std::out_of_range'
what(): throw_allocator::throw_conditionally
random number generated is: 3499211612.00
Abort
Gives me this for C++0x (-std=gnu++0x)

Interpretation request tracking bug * * * Found at http://groups.google.com/group/comp.lang.fortran/browse_thread/thread/c05874d85748d9e6 The problem is function f() result(res) res = f(something) where f is both a specific and a generic function and f(something) matches a the different generic function. However, Section 12.5.2.1 of Fortran 2003 has: If RESULT is specified, [...] all occurrences of the function name in execution-part statements in the scoping unit refer to the function itself. This somehow clashes with other parts of the standard and it is currently unclear whether the program is valid.

[Bug target/40265] New: sh2a compiler ICEs in simplify_subreg, at simplify-rtx.c:4960
Newlib build fails during compiling libc/stdlib/ldtoa.c for m2a with
internal compiler error: in simplify_subreg, at simplify-rtx.c:4960
A reduced testcase is
void
foo (unsigned short *x, unsigned short *y)
{
unsigned short *p = x;
*y = 0;
if (*p++)
*y = 0x8000;
}
For m2a, movrt insn is defined as
(define_insn movrt
[(set (match_operand:SI 0 arith_reg_dest =r)

(const_int 1)
(const_int 0)))]
TARGET_SH2A
movrt\\t%0
[(set_attr type arith)])
and now sh.c:sh_expand_t_scc generates this insn as an scc
instruction. It seems that it's too complex as an scc insn
and confuses the combine phase. I'm testing the patch below
which uses another movrt insn with more simple arithmetic
definition
