We have a regression in C++ in 4.8 there. Comparing -O3 -fdump-tree-optimized
in gcc-4.7, g++-4.7 and gcc-4.8:
D.1708_3 = a_1(D) r shift_2(D);

shift.0_2 = (int) shift_1(D);
_4 = a_3(D) shift.0_2;
_5 = 64 - shift_1(D);
_6 = (int) _5;
_7 = a_3(D) _6;

The code with intrinsics still has the extra move, but note that this version
without intrinsics generates perfect code:

__m256d z={x[0],x[1],x[0],x[1]};

Thanks.
This is exactly what is happening. From gcov-dump on test.gcda:
test.gcda: a300: 22:PROGRAM_SUMMARY checksum=0x01847361
test.gcda: counts=617, runs=5, sum_all=0, run_max=0, sum_max=0
test.gcda: counter histogram:
test.gcda: 0: num counts=617, min counter=0, cum_counter=0
Not sure why there are no non-zero counters when there are 0 runs,
but the above patch handles this situation.
Will send in patch a little later today when bootstrap tests complete.

indeed.
and now this other vectorizes also on corei7 (yesterday was ok only with AVX)
float64x4_t cross_product(float64x4_t x, float64x4_t y) {
// yz - zy, zx - xz, xy - yx, 0
float64x4_t x1200 = (float64x4_t){ x[1], x[2], x[0], x[0] };
float64x4_t y1200 = (float64x4_t){ y[1], y[2], y[0], y[0] };
float64x4_t x2010 = (float64x4_t){ x[2], x[0], x[1], x[0] };
float64x4_t y2010 = (float64x4_t){ y[2], y[0], y[1], y[0] };
return x1200 * y2010 - x2010 * y1200;
}
the generated code (particularly on AVX) looks comparable to handcrafted one.
(for float32x4 even nicer)
congrats…

That is weird because it is showing the parameters in reverse order. Is that
what gdb normally does on your system? It doesn't seem to do it for other
functions.
No, I've never seen it before. Then again, before yesterday I had never used
GDB 7.5, only older versions.
Here gdb says that the value of dwarf_info is out of bounds. That is not
good.
That is most likely the immediate cause of the problem. (dwarf_ranges is
also
out of bounds, but that likely doesn't matter as dwarf_ranges_size is zero.)
It looks like it had trouble getting the debug info for the executable file
itself. Can you add the output of readelf -S on the executable?

[Bug c++/55557] New: g++ 4.7 does not issue a warning on the first auto_ptr
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=7
Bug #: 7
Summary: g++ 4.7 does not issue a warning on the first auto_ptr
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: pashev.i...@gmail.com
Here is a C++ source code:
# cat -n test.cpp
1 #include memory
2 using namespace std;
3
4 int main(int argc, char **argv)
5 {
6 auto_ptrint x;
7 auto_ptrint y;
8 auto_ptrint z;
9
10 return 0;
11 }
Command line to compile it with C++11 standard:
g++-4.7 -std=gnu++11 -Wall -Wextra -Wdeprecated-declarations -pedantic
test.cpp
Here is the g++ output:
test.cpp: In function ‘int main(int, char**)’:
test.cpp:7:19: warning: ‘auto_ptr’ is deprecated (declared at
/usr/include/c++/4.7/backward/auto_ptr.h:87) [-Wdeprecated-declarations]

A warning about auto_ptr being deprecated has been issued only for y and z. I
expect a warning for x too.
Moreover, if I leave only one auto_ptr (say, x) I will see no deprecation
warning at all.
It is expected to see warning on every auto_ptr instantiation.

[Bug c++/55558] New: [C++11] decltype on a static member variable of a specialized class in a template function results in an internal compiler error
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=8
Bug #: 8
Summary: [C++11] decltype on a static member variable of a
specialized class in a template function results in an
internal compiler error
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: dev...@gmx.net
The following piece of code:
templateclass T class A
{
};
class B
{
};
template class AB
{
public:
static int member;
};
templatetypename T void foobar ()
{
typedef decltype (AB::member) myType;
}
produces the following error:
test.cpp: In function 'void foobar()':
test.cpp:17:32: internal compiler error: in finish_decltype_type, at
cp/semantics.c:5274
I accidently used the actual class B instead of the template parameter T in the
foobar function and stumbled upon this error. The error is NOT reproducible
when at least ONE of the following points applies:
- the member variable 'member' is not static
- 'foobar' is not a template method
- the expression inside the decltype statement is inside another expression,
e.g. a function call or as an operand to an operator
The typedef expression is not relevant for the error, it also happens when the
decltype expression is used to declare a variable or as a template parameter.

Well, this is awkward, not even a template class is needed, the following code
also produces the bug:
struct A
{
static int member;
};
templatetypename T void foobar ()
{
typedef decltype (A::member) myType;

It also eliminates PR55521 by avoiding the use of mach_override. It still needs some cleanup. In particular, I have used 'if 0' to avoid dispatch calls on FSF gcc which required the missing blocks support. This needs to be replaced by a test on an appropriate definition specific to FSF gcc (any ideas?). As I understand it, the use of blocks is for objc which isn't a huge deal at the moment.

Also on x86_64-apple-darwin12, the switch from mach_override to mac function interposition reduces the unexpected failures in the g++ testsuite from 841 to 323. This is still far more than seen under x86_64 Fedora 15 (which shows 107) but still is a major improvement over mach_override.

[Bug other/55560] New: fesetround(FE_DOWNWARD) causes cos() to return values outside the range of -1 to +1
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55560
Bug #: 55560
Summary: fesetround(FE_DOWNWARD) causes cos() to return values
outside the range of -1 to +1
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: other
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: p...@ecstaticlyrics.com
Created attachment 28852
-- http://gcc.gnu.org/bugzilla/attachment.cgi?id=28852
Contents of /proc/cpuinfo
Simple test program:
#include stdio.h
#include math.h
#include fenv.h
void main() {
double a, c;
fesetround(FE_DOWNWARD);
for (a = -M_PI; a = +M_PI; a += 0.01) {
c = cos(a);
if (c -1.0 || c +1.0) {
printf(cos(%f) is not %f\n, a, c);
};
};
};
Compile like so: gcc -o test test.c -lm
Expected output is nothing at all, since cos() always returns values between
-1.0 and +1.0. The actual output, however, is 20,009 lines. Here are the
first ten:
cos(-3.141593) is not -1.000485
cos(2.430171) is not 3614403565883090812337301068370710204239577088.00
cos(2.430172) is not 195176399637579483727029815821181674649563430912.00
cos(2.430173) is not 386738395709080693943503989636585388708949131264.00
cos(2.430174) is not 578300391780195078044017318793663580791807934464.00
cos(2.430175) is not 769862387850731413470826575343659276213015281664.00
cos(2.430176) is not 961424383920497666369804385270998542397395173376.00
cos(2.430177) is not 1152986379989302370794292276806879317292807618560.00
cos(2.430178) is not 1344548376056954223056908607395862930425122914304.00

The problem disappears if the test program is compiled with -m32 or if
fesetround(FE_DOWNWARD) is removed.

Have you tried a newer version of glibc like say 2.16? Oh what version of glibc are you using? find out by invoking /lib/libc.so.6 .
