--- Comment #2 from jakub at gcc dot gnu dot org 2009-01-17 08:00 --- Then _Jv_GetStringChars should be dropped from libgcj_bc.so too. And for the other function, I think adding a "C" alias in libgcj.so.* and a C++ in libgcj_bc.so wouldn't hurt. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38872

[Bug libstdc++/35569] [c++0x] std::bind result functor doesn't accept rvalues
--- Comment #6 from paolo dot carlini at oracle dot com 2009-01-17 09:04 --- Maybe this issue isn't sufficiently clarified in the audit. Unless I'm badly mistaken (Jon, Chris will correct me), this is not a bug for a C++03 + TR1 bind (indeed the testcases provided by Doug are rather clear about that). Only in C++0x the specs say it must work. Of course implementations can also "fix" it for C++03 + TR1, but this is not in general the way we are managing these issues, we prefer leaving the TR1 version alone. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35569

The symbol was added with Rev. 126185 (2007-07-01) and removed with Rev. 135877 (2008-05-25). The first SoC 2008 proc pointer patch was Rev. 137386 on 2008-07-02.

As one cannot rule out that some invalid program uses c_f_funpointer, I will submit a patch which re-adds it.

The procedure name is "C_F_PROCPOINTER" (-proc- not -FUN-). (It's C_FUNLOC and type(c_funptr) but c_f_procpointer). There is no argument checking, but the library function called is __iso_c_binding_c_f_procpointer_i4 ! note extra _i4. (which does not exist).

[Bug tree-optimization/38895] New: missed type-based disambiguation
RTL alias analysis (nonoverlapping_component_refs_p) with a quadratic loop
finds that c->a1.i and b->a1.j cannot alias based on a offset test on the
common sub-reference base a1. The tree based alias oracle only does two
linear searches for the base type *c in b->a1.j and for *b in c->a1.i.
This is related to PR13146 where even that is not enough, but a
(non-conservative?) answer based on not finding a common base needs to be
given.

Note that we have to be very careful here because
struct X {

struct A {
int i;
};
struct B {
struct A a;
int j;
};
int foo (struct X *p, struct B *q)

q->a.i = 1;
return p->i;
}
may be aliasing. One need to consult the C standard and defect reports again
for the "common initial sequence" in structs stuff.

Hi
My mistake was to export a function in the bash to fool a shell script. But
then I configured GCC without removing it.
I did :
function install() { ginstall "$@"; }
export -f install
Then I configured GCC, which led to the problem. Thanks to Ralf :
./config.status -d
config.status: creating as
sed: file ./confstatg0aq6N/subs-5.sed line 7: unterminated `s' command
config.status: creating collect-ld

[Bug rtl-optimization/38879] scheduler does not look for conflicting alias sets
--- Comment #1 from ubizjak at gmail dot com 2009-01-17 17:04 ---
The problem is in a thinko in alias.c, base_alias_check (). For our problematic
addresses, we enter base_alias_check with:
x = (reg:DI 18 $18 [ i ])
and
y = (and:DI (reg/f:DI 16 $16 [orig:69 __result ] [69])
(const_int -8 [0xfff8]))
We actually have the code that handles this situation, just after the comment:
/* The base addresses of the read and write are different expressions.
If they are both symbols and they are not accessed via AND, there is
no conflict. We can bring knowledge of object alignment into play
here. For example, on alpha, "char a, b;" can alias one another,
though "char a; long b;" cannot. */
At the start of this code, we have:
base_x = (address (reg:DI 18 $18))
and
base_y = (address (reg:DI 16 $16))
These RTXes should trigger the code that analyses addresses involving AND
operation. So, actually we have to reverse the guarding condition!
Following patch fixes the failure:

Now, the scheduler creates correct schedule:

[Bug libstdc++/38897] New: Parallel mode example code does not compile
Compilation fails of the small code sample found at:
http://gcc.gnu.org/onlinedocs/libstdc++/manual/bk01pt12ch31s03.html
I am using the suggested compiler options.
This is the code (cut and pasted from your documentation):
#include
#include
int main()
{
std::vector v(100);
// ...
// Explicitly force a call to parallel sort.
__gnu_parallel::sort(v.begin(), v.end());
return 0;
}
If it is this code that is incorrect the docs should be fixed as there are not
many examples of parallel libstdc++ usage to be found on the net at the
moment.
This is g++ output:

So it can't resolve the ambiguous overloading between a parallel and
non-parallel version of sort.
I am not sure which -march option i should be using, but i tried using none,
-march=i686, and -march=native, with identical results.
This is an up-to-date ubuntu 8.10, by the way.

Hm, no. The code is correct, but applies only to symbols involving ANDs.
We need somehing like this code also for the case when one of operands is

[Bug target/38899] New: pessimizes function without SSE intrinsics
[ Forwarded from http://bugs.debian.org/512050 ] brian m. carlson reports the following problem with gcc 4.3 and trunk: Attached is a C file that is compiled with -O3. mul and mul2 perform the same operation; mul uses a loop, and mul2 uses SSE intrinsics. mul2 results in three instructions, whereas mul results in many, many more. Obviously, since the two functions do the exact same thing, they should be optimized to be identical. Instead, mul is pessimized. Note that there are no alignment issues present since the arrays declared in main are 16-byte aligned (since they are allocated on the stack, which is 16-byte aligned on x86_64). And: I also just noted that gcc-4.1 and gcc-4.2 produce much less bad code: they each use 8 movss and 4 mulss. Nevertheless, they still do not convert the code into three SSE instructions. -- Summary: pessimizes function without SSE intrinsics Product: gcc Version: 4.3.2 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: tbm at cyrius dot com GCC target triplet: x86_64-unknown-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38899

[Bug inline-asm/38901] New: Inline assembly swallows mmx register on duplicate input under optimization
I've tested this under gcc 4.2.1 (DJGPP) and gcc 3.4.4 (cygwin) (see below for
gcc -v outputs). The test program is simple: generate two random complex
numbers, multiply them using the FPU, and do it again using 3dnow inline
assembly. I can get it to work with different code, but this version
illustrates an apparent bug in the optimization scheme.
Compiling as gcc -m3dnow cdtest.c produces the correct output:
x = 0.122114 + 0.096877iy = 0.372626 + 0.199503i
z = 0.026175 + 0.060461iz = 0.026175 + 0.060461i
Compiling as above with an additional -O(1,2, or 3) produces:
x = 0.122114 + 0.096877iy = 0.372626 + 0.199503i
z = 0.026175 + 0.060461iz = 0.011737 + 0.018312i
with the inline-assembly (second) value wrong.
--- cdtest.c
#include
#include
#define fRand()(((float)rand())/RAND_MAX)
typedef struct fComp { float x,y; } fComp __attribute__ ((aligned (8)));
#define fCIni(d,X,Y) do { (d)->x = (X); (d)->y = (Y); } while(0)
int main(int nArgs, char *Args[], char *Env[]) {
fComp x,y,z; /* x,y random complex numbers, z = x*y */
fCIni(&x,fRand(),fRand()); fCIni(&y,fRand(),fRand());
fCIni(&z,x.x*y.x - x.y*y.y, x.x*y.y + x.y*y.x);
printf("x = %f + %fi\ty = %f + %fi\nz = %f + %fi\t",x.x,x.y,y.x,y.y,z.x,z.y);
/* Recalculate the same product using 3dNow */
asm("pswapd %[X],%[X]\n\t"/* X = r1 | i1 */
"pfmul%[Y],%[Z]\n\t"/* Z = i1i2 | r1r2 */
"pfmul%[X],%[Y]\n\t"/* Y = r1i2 | r2i1 */
"pfpnacc %[Y],%[Z]\n\t"/* Z = r1i2+r2i1 | r1r2-i1i2 */
"movq %[Z],(%[Zp])" /* Store result at *Zp */
:
: [X]"y"(x), [Y]"y"(y), [Z]"y"(x), [Zp]"r"(&z)
: "memory" );
asm("femms");
printf("z = %f + %fi\n", z.x, z.y);
return 0;
}
Inspecting the .s output, the unoptimized compilation assigns
[X] = %mm0, [Y] = %mm1, [Z] = %mm2,
while the optimized version fails to work because of the duplication
[X] = %mm0, [Y] = %mm1, [Z] = %mm0.
This seems to happen because both X and Z are initialized to the same value;
doing [Z]"y"(0) or something similar (and movq %[X],%[Z] manually) resolves the
problem, but with an unfortunate side-effect that %[Z] is actually set twice,
wasting instructions. It would be saner for the compiler to just automatically
re-copy the first instance to the second one, rather than erroneously
concluding that I don't really need the extra register just because it has the
same input value.

gcc version 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)
A similar problem occurs if I replace the first inline asm with:
asm("movq %[X],%[Z]\n\t"
"pswapd %[X],%[X]\n\t"/* X = r1 | i1 */
"pfmul%[Y],%[Z]\n\t"/* Z = i1i2 | r1r2 */
"pfmul%[X],%[Y]\n\t"/* Y = r1i2 | r2i1 */
"pfpnacc %[Y],%[Z]\n\t"/* Z = r1i2+r2i1 | r1r2-i1i2 */
: [Z]"=y"(z)
: [X]"y"(x), [Y]"y"(y) );
both [Z] and [X] again being mapped to the same register. (This code also even
more wasteful, but that's not the point.)
BTW: Is there any way to tell gcc that I need a random register different from
the rest, but I don't care about its initial value--something like [foo]"y"()
in inputs or [bar]"y" in clobber? I know if I put, say "mm0" in the clobber
list, then gcc seems to know to pick different ones for [X],[Y],[Z], but
letting gcc pick one would be a convenient feature.

[Bug target/38904] New: Shared libgcc DLL violates Cygwin platform conventions.
The shared libgcc DLL currently built for cygwin is named "libgcc_s_1.dll", and it comes with an import library named "libgcc_s.a". These both violate the Cygwin platform naming conventions. All DLLs are prefixed with 'cyg' rather than 'lib' on the Cygwin target, and the corresponding import library should be prefixed with 'lib' and use a '.dll.a' extension. Although this is a problem in a new feature, rather than a regression, I will appeal for special consideration (as a target-specific change) to apply a patch (that I will post shortly) for this issue during stage 4, so that it can be in the released GCC 4.4 series, avoiding an ABI break between 4.4 and 4.5 on the Cygwin platform. -- Summary: Shared libgcc DLL violates Cygwin platform conventions.

[Bug bootstrap/37660] [4.4 Regression] Error Building libssp, recent update
--- Comment #7 from dave dot korn dot cygwin at gmail dot com 2009-01-18 05:57 --- Created an attachment (id=17132) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=17132&action=view) Move _ctors* and _chkstk* to import lib Danny, this is the approach that I think I'd like to take for Cygwin; what do you think about doing it this way? I'm currently testing a full bootstrap using this patch. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37660
