It declares a private C99-compliant snprintf() implementation and invokes it with %zu and %llx formats.

[Bug rtl-optimization/37784] New: inefficient code for double compare double yielding double
The function:
double dfunc_001 ( const double a, const double b) { return a b; }
yields the x86_64 code:
cmpltsd %xmm0, %xmm1
movapd %xmm1, %xmm0
movsd .LC1(%rip), %xmm1

xorpd %xmm2, %xmm2
andnpd %xmm2, %xmm0
orpd%xmm1, %xmm0
ret
.LC1:
.long 0
.long 1072693248
Where LC1 is the fp constant +1.0
The 3 instruction sequence preceding the ret (eg xorpd;andnpd;orpd) is not
needed. The xorpd generates a 0, which is anded with something to yield a 0,
which is or'ed in with the value (+0.0 or +1.0) to yield the result.
Similar illness is seen for the other compares built around cmpsd variants.
Some improvement is seen when compiling -O3, but in that case there are 2
unneeded instructions.

[Bug c/37785] New: printf + sleep = problems with output buffer
PLATFORM
PC i386 + GNU/Linux Ubuntu Hardy 8.04 + GCC 4.2.3
Compiling and Linking options: none.
Excuse my poor English. (By the way, what is Host triplet, Target triplet,
Build triplet?)
BUG:
printf really prints at terminal when finds '\n' character. So if I have a
simple printf iteration without '\n' like this ...
int n;
for (n=10; n=0; n--) {
printf(%d , n);
sleep(1);
};
... it doesn't works like expected. It just waits 10 seconds without printing
anything. After that prints whole line.
Another related problem with printf without '\n' and printf buffer using fork,
but I don't know if it is problem with printf or fork:
int n, pid;
for (n=10; n=0; n--) {
printf(%d , n);
sleep(1);
};
pid = fork();
if (pid == -1)
printf(Error\n);
else
if (pid == 0)
printf(I'm the child\n);
else
printf(I'm the parent\n);
it prints TWO times 10 9 8 7 6 5 4 3 2 1 0
It is not that executes two times, but if the fork send again the buffer to the
screen.

There is no changes needed here for the documentation as far as I can tell so closing as invalid. Dear bugmeister, At the very least the documentation could be made less confusing. The documentation for GNU ld gives: `-Bsymbolic' When creating a shared library, bind references to global symbols to the definition within the shared library, if any. Normally, it is possible for a program linked against a shared library to override the definition within the shared library. This option is only meaningful on ELF platforms which support shared libraries. The wording is sufficiently similar that one might think `-symbolic' and `-Bsymbolic' have the same meaning. Yet on x86-linux-gnu, the first fails, while the second appears to succeed. $ gcc -symbolic main.c; echo --; gcc -Bsymbolic main.c gcc: unrecognized option '-symbolic' -- Also, gcc has a documented `-B' flag with a completely different meaning. All in all, I think there is at least scope for improved clarity in the documentation. I've used gcc for decades, but am still confused. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37786

[Bug fortran/37787] New: right-left hand side overlap not recognized with EQUIVALENCEd array assignment
The following program fails to recognize that the equivalence between qla1 and qla2 causes a dependency in the assignment.

--- Comment #9 from reichelt at gcc dot gnu dot org 2008-10-09 20:51

I just stumbled over the same bug and a similar ICE in vectorizable_store:
The following valid code snippet triggers an ICE on mainline when compiled
with -march=pentium4 -O2 -ftree-vectorize on i686-pc-linux-gnu:
==
void foo(int* __restrict__ p, int* q, int* p1, int *q1)
{
int i;
p = p1;
q = q1;
for (i = 0; i 4; ++i)
*++q = *++p + 1;
}
==
bug.c: In function 'foo':
bug.c:1: internal compiler error: in vectorizable_load, at
tree-vect-transform.c:6675
Please submit a full bug report, [etc.]
Moving the restrict keyword triggers a slightly different ICE:
==
void foo(int* p, int* __restrict__ q, int* p1, int *q1)
{
int i;
p = p1;
q = q1;
for (i = 0; i 4; ++i)
*++q = *++p + 1;
}
==

The test case gcc-c-torture/compile/limits-fnargs.c takes multiple hours to compile at -O2 or above optimization on IA64. It looks like most of the time is spent in IRA. The IRA pass calls reload which calls ira_sort_regnos_for_alter_reg with n = 28977. This in turn calls coalesce_spill_slots with num = 10061.

[Bug driver/37786] Documentation for `-symbolic' needs fixing
--- Comment #5 from martinrb at google dot com 2008-10-09 23:10 --- (In reply to comment #4) If you want to use a specific linker option, use -Wl,XYZ or -Xlinker XYZ . Since those are the documented way to pass a linker option via gcc. I know about -Wl, and -Xlinker. I am trying to reduce confusion, for myself in part, but mostly for others. The flag `-Bsymbolic' works (or at least is accepted) despite the fact that it is not documented that such a flag is passed to the linker. This appears to be an undocumented use of `-B'. And on the other hand, the documented flag `-symbolic', which appears to have the same meaning, is rejected.
