struct A { int a[2]; A():a({1, 2}) { } };
Should be valid. Example:
class cond_variable
{
::pthread_cond_t cond;
public:
constexpr cond_variable() : cond(PTHREAD_COND_INITIALIZER) {}
};
What is pthread_cond_t? Struct? Array? Scalar? How I can be sure this code is
accepted in any case? Uniform initialization initially address this issue.
Out of constructor one can use =:
::pthread_cond_t cond = PTHREAD_COND_INITIALIZER;
In constructor init-list = is prohibited therefore () must play a same
role.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31067 --- Comment #46 from Tobias Burnus burnus at gcc dot gnu.org 2011-07-29 07:12:47 UTC --- (In reply to comment #45) [Commit to inline MINLOC/MAXLOC for a rank-1 array, which returns a single-element rank-1 array.] On my ~5 year old Athlon64 x2, I get with -Ofast -march=native (and with or without -fwhole-program) a performance improvement of 3% (10.72s - 10.41s). The performance should further improve, if one fuses the loops (cf. comment 42, but also comment 34 ff.) - and if one could move the memory allocation/freeing of the automatic-array DTEMP out of the loop (after inlining). (Recall that with -fstack-arrays/-Ofast, automatic arrays are allocated on the stack.) As already mentioned indirectly in comment 0 (via PR31066): If one uses reciprocal approximation instructions and a Newton-Rhapson step (namely: -mrecip), the performance improves a lot: 6.895s. By comparison, with ifort (11.1) -xHost -O3 the run time is 7.319s.

[Bug c++/49896] New: undefined reference to static const integral member whose address is not used, for some values of the constant
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49896
Summary: undefined reference to static const integral member
whose address is not used, for some values of the
constant
Product: gcc
Version: 4.6.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: matthieu.imb...@ens-lyon.fr
A static const int member is declared and initialized in a template class.
Its value (not its address) is used in a method of the class.
If the value of the constant has its most significant bit set (int is 32 bits),
then there is an undefined reference to the member at link.
Here is a code snippet to reproduce this:
snippet test.cpp
templateclass C
class test {
protected:
static const int version = 0x8000;
//static const int version = 0x0fff;
public:
int getVersion();
};
templateclass C
int testC::getVersion() {
return version;
}
class dummy_class {};
int main() {
testdummy_class t;
return t.getVersion();
}
end of snippet
compilation:
$ gcc -Wall -Wextra -Wstrict-aliasing test2.cpp
/tmp/cc4duaE3.o: In function `testdummy_class::getVersion()':
test2.cpp:(.text._ZN4testI11dummy_classE10getVersionEv[testdummy_class::getVersion()]+0xa):
undefined reference to `testdummy_class::version'
collect2: ld returned 1 exit status
if the constant value is 0x0fff instead of 0x8000 it compiles fine.
i get this issue on this version of gcc (the default version currently on
debian testing):
$ gcc -v

Nesting lastprivate doesn't work in gcc 4.5: the inner loop has a lastprivate
variable that is then also declared lastprivate on the outer loop (otherwise
there would be a race), but the result after the loop is always 0. It works
fine in gcc 4.2 to 4.4.

The following example fails in gcc 4.5 but works in gcc 4.4. The inner loops
has a reduction that is again a reduction in the outer loop. The result should
be 450, but is always 0. If you put the reduction() clauses on the #pragma omp
parallel it does work.

Product: gcc
Version: 4.7.0

Proposed patch and new testcase
If an already defined static function is redefined as being both public and
weak, the compiler generates an ICE:
% cat test.c
static long foo (void) { return 0; }
long foo (void) __attribute__((weak));
% gcc test.c
test.c:1:12: internal compiler error: in function_and_variable_visibility,
at ipa.c:408
The uploaded patch is an attempt to fix this by adding a check into
varasm.c:merge_weak(). I was not sure however whether the redeclaration is an
error, or if it should be honoured and the function made non-static.
[Bug c++/49896] undefined reference to static const integral member whose address is not used, for some values of the constant
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49896 --- Comment #2 from Matthieu Imbert matthieu.imb...@ens-lyon.fr 2011-07-29 10:37:33 UTC --- (In reply to comment #1) You lack a definition of testC::version. C++ standard section 9.4.2 states: If a 'static' data member is of 'const' integral or 'const' enumeral type, its declaration in the class definition can specify a 'constant-initializer' which shall be an integral constant expression (5.19). In that case, the member can appear in integral constant expressions. The member shall still be defined in a namespace scope if it is used in the program and the namespace scope definition shall not contain an 'initializer'. The notion of used is defined in section 3.2: An object or non-overloaded function whose name appears as a potentially- evaluated expression is used unless it is an object that satisfies the requirements for appearing in a constant expression (5.19 [expr.const]) and the lvalue-to-rvalue conversion (4.1 [conv.lval]) is immediately applied. I am not a C++ expert but various sources (for example: stroustrup C++ faq: http://www2.research.att.com/~bs/bs_faq2.html#in-class) seem to say that the code snippet i sent is valid since the address of testC::version is not taken. Stroustrup says: You can take the address of a static member if (and only if) it has an out-of-class definition, which i interpret as: no need for a definition if address not taken. So in brief, i think there is no need to define testC::version to be correct.

[Bug target/49687] [4.6 Regression][avr] Missed optimization for widening MUL
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49687 --- Comment #7 from Georg-Johann Lay gjl at gcc dot gnu.org 2011-07-29 11:49:30 UTC --- With this milestone the work for better support for widening multiplication is finished -- fir the case when MUL instruction is available. Similar work for the case when no hardware multiplier is available needs still to be done. The preferred approach in that case is to do the extension explicitely in libgcc prior to the multiplication. Respective code was already included in libgcc but dead because no one calls it up to now.

[Bug c++/47453] Various non-conforming behaviors with braced-init-list initialization
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47453
--- Comment #5 from Johannes Schaub schaub.johannes at googlemail dot com
2011-07-29 12:23:35 UTC ---
(In reply to comment #4)
struct A { int a[2]; A():a({1, 2}) { } };
Should be valid. Example:
class cond_variable
{
::pthread_cond_t cond;
public:
constexpr cond_variable() : cond(PTHREAD_COND_INITIALIZER) {}
};
What is pthread_cond_t? Struct? Array? Scalar? How I can be sure this code is
accepted in any case? Uniform initialization initially address this issue.
Why not say
constexpr cond_variable() : cond PTHREAD_COND_INITIALIZER { }
Out of constructor one can use =:
::pthread_cond_t cond = PTHREAD_COND_INITIALIZER;
You can define it as follows to make it work in both cases
#define PTHREAD_COND_INITIALIZER {}

(dwarf2out_define): If the vector is empty and
lineno is 0, emit a dummy entry first.
(dwarf2out_undef): Likewise. Remove redundant semicolon.
(htab_macinfo_hash, htab_macinfo_eq, output_macinfo_op,
optimize_macinfo_range): New functions.
(output_macinfo): Use them. If !dwarf_strict and .debug_str is
mergeable, optimize longer strings using
DW_MACRO_GNU_{define,undef}_indirect and if HAVE_COMDAT_GROUP,
optimize longer sequences of define/undef ops from headers
using DW_MACRO_GNU_transparent_include. For !dwarf_strict
emit a section headers.
(dwarf2out_init): For !dwarf_strict set debug_macinfo_section
and macinfo_section_label to DEBUG_MACRO_SECTION
resp. DEBUG_MACRO_SECTION_LABEL.
(dwarf2out_finish): For !dwarf_strict emit DW_AT_GNU_macros

In my experience this type of check is really noisy if there is a warning for
every fall through.
I recommend that the warning is written only if the fall through cause
redundant or bad behaviour. such as:
switch (foo) {
case 1: x = y; // - redundant assignment
case 2: x = z;
};
Or:
switch (foo) {
case 1: p = NULL;
case 2: *p = 2;// fall through = NULL pointer dereference
};

[Bug target/49903] [avr] Redundant comparisons in binary-search switch/case expansion
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49903 --- Comment #2 from Georg-Johann Lay gjl at gcc dot gnu.org 2011-07-29 16:11:12 UTC --- (In reply to comment #1) Johann, Would some type of peephole optimization help out on this? RTL peephole won't work because they operate just inside basic blocks. Don't know the retionale behind that limitation, appears that it's just for technical and implementational reasons. RTL peep need not to be confused by BBs, just code_labels etc. would bother. Text peepholes match but it might be tedious and error prone to work out instructions lengths or the correct instructions if jump offsets don't match. Maybe a way is in avr_reorg, but it would be quite tedious to work out all QI/HI/SI signed and unsigned combinations. And it must ensure that no other transformation takes place. There's bunch of special treatment in md and c and cc0 handling. E.g. I don't quite understand why jumps clobber cc0; btw not clobbering cc0 will not fix this PR.

D.1569 = NON_LVALUE_EXPR SAVE_EXPR D.1567 + 7 -8;
D.1570 = NON_LVALUE_EXPR SAVE_EXPR D.1568;
character(kind=1) bad_rec[1][1:.bad_rec];
}
...some code that does the write...
.bad_rec has the correct value (80) later on in the print-statement. However,
the code above (last line before }) looks to me as if bad_rec was created just
inside the shown block -- and is later no more available on the stack or
something, thus crashing the program.
So it seems that evaluating the max(...) creates the block shown above, and the
allocation of the automatic array is accidentally placed inside that block.
This seems like a plausible cause for this bug.
Now I'll try to find out how to fix it.

0x8000 is (possibly wrongly) rejected as an integer constant expression,
because it is not within int's range. It is accepted with an explicit cast.
With a slight modification, it triggers an ICE:
templateclass C
class test {
protected:
static const int versionConst = 0x8000;
enum { versionEnum = versionConst };
public:
int getVersion();
};

return versionEnum;
}
class dummy_class {};
int main() {
testdummy_class t;
return t.getVersion();
}

[Bug c/49905] New: Better sanity checking on sprintf src dest to produce warning for dodgy code ?
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49905
Summary: Better sanity checking on sprintf src dest to
produce warning for dodgy code ?
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: c
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: dcb...@hotmail.com
I just tried to compile the following C++ code with the latest trunk
snapshot 20110723 on an AMD x86_64 box.
# include stdio.h
void f()
{
char * p = new char [4];
char q[4];
sprintf(p, ian); // Legal
sprintf(q, ian);
sprintf(p, bert); // One over
sprintf(q, bert);
sprintf(p, harry);// definately wrong.
sprintf(q, harry);
sprintf(p, %s, harry); // more subtle.
sprintf(q, %s, harry);
sprintf(p, %s %s, ab, cd);// more subtle still.
sprintf(q, %s %s, ab, cd);
sprintf(p, %s %d, ab, 1000);// overpoints.
sprintf(q, %s %d, ab, 1000);
}
Much to my surprise, the compiler, even with lots of flags, said not much
bash-4.2$ ~/gcc/20110723/results/bin/g++ -c -O2 -Wall -Wextra -pedantic
bug29.cc
bash-4.2$
I'd have expected a few warnings, at very least.
Surely something in the compiler could be done to check that sprintf is
called, the destination buffer size is known, the minimum source buffer
size is known, and compare the two to make sure the source fits inside
the destination ?
Such a warning will in my experience find plenty of bugs in application code.

For the first three overflows on q you'll get compile time warnings, and for all overflows on q you'll get the program killed at runtime. If you use char * p = (char *) malloc (4); instead of char * p = new char [4]; you'll get protection for the p overflows too, I'll see if __builtin_object_size could be taught about C++ new, at least some forms thereof.

(In reply to comment #1)
Use --disable-multilib.
Not an option for us on fink since the same packaging script has to both list
the built shared libraries
and run on both non-EMT64 and EMT64 processors. For now, I am forced to just
short circuit the
test locally with the hack...

so that libquadmath can be built like all the other 64-bit binaries regardless
of EMT64 support.
