--- Comment #4 from jakub at gcc dot gnu dot org 2009-12-23 08:41 --- While that change triggered it because at *.ifcvt it causes a difference: bb 7: i_41 = j_4(D); - # DEBUG i = NULL + # DEBUG i = i_9 if (i_41 = 4095) goto bb 3; it doesn't to appear to be the bug, i_9 definition dominates this use.

[Bug bootstrap/42474] New: SIGSEGV in linemap_lookup
While building gcc from tag gcc_4_4_1_release on Haiku, a segfault occurred several times in various files, in the same location in linemap_lookup: mn = set-cache; The set variable is NULL. I changed linemap_lookup to return NULL when the set is NULL and this problem went away. I also experienced this SIGSEGV while using gcc 4.3.3 on Haiku.

[Bug c++/42472] class members not getting assigned access thru another method
--- Comment #1 from redi at gcc dot gnu dot org 2009-12-23 11:09 ---
C++ is not java, you cannot delegate to another constructor like this:
primes::primes(ulong p):maxp(p) { primes(); }
That creates a temporary object of type primes, it does not call the
constructor.
Therefore primes::i and primes::p are not initialised by the primes(long)
constructor.

[Bug c/42476] New: warning: will never be executed about code which is executed with -Wunreachable-code
Compiling the following code snippet:
int main(int argc, char **argv)
{
int i;
int asize = 3;
int array[3];
for (i = asize - 1; i asize; i++)
array[i] = 42;
for (i = 0; i asize; i++)
printf(%i\n, array[i]);
}
with gcc -O -Wunreachable-code gccbug.c shows the following warning message:
gccbug.c: In function 'main':
gccbug.c:8: warning: will never be executed
(Where line 8 is the body of the first for-loop, array[i] = 42;)
Though, array[2] is set to 42, as the later printf shows when executing.
When replacing the - 1 of line 7 with an higher value, e.g. - 2, the
warning disappears. Not passing -O to the compiler lets the warning
disappear, too.

[Bug translation/42467] exgettext should not remove TABs from option help strings
--- Comment #3 from jsm28 at gcc dot gnu dot org 2009-12-23 11:58 --- The option help string is passed for translation as a whole before the special interpretation for TAB as described in options.texi: The help text is automatically line-wrapped before being displayed. Normally the name of the option is printed on the left-hand side of the output and the help text is printed on the right. However, if the help text contains a tab character, the text to the left of the tab is used instead of the option's name and the text to the right of the tab forms the help text. This allows you to elaborate on what type of argument the option takes. Thus, exgettext is wrong to remove the text before the tab (which generally does need translation of things such as options). -- jsm28 at gcc dot gnu dot org changed: What|Removed |Added OtherBugsDependingO||40883 nThis|| Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 Last reconfirmed|-00-00 00:00:00 |2009-12-23 11:58:25 date|| Summary|Localization fails with - |exgettext should not remove |gnatoptions line in gcc --|TABs from option help |help=Ada|strings http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42467

[Bug fortran/42477] New: Runtime segfault with -fopenmp -static
Consider this simple program: use omp_lib print *, 'Number of processors:', omp_get_num_procs() end After compiling this with -fopenmp -static -fbacktrace, executing it gives the output: Number of processors: 2 Program received signal 11 (SIGSEGV): Segmentation fault. Backtrace for this error: + function __restore_rt (0x41EAB0) from file sigaction.c The segfault is gone when compiling without the -static flag. Also this seems to be a Fortran-only problem. An equivalent C program does not run into the segfault. -- Summary: Runtime segfault with -fopenmp -static Product: gcc Version: 4.5.0 Status: UNCONFIRMED Keywords: wrong-code Severity: normal Priority: P3 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: janus at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42477

read() wont allow me to read files larger than 2 gig (on a 64bit)
Hi Sorry if I'm asking on the wrong mailinglist, but I've asked on various forums and I havn't found a solution. I can't read files larger than 2 gig on my ubuntu64bit using 'read()', the problem is not related to the allocation itself, which works. Attached is a sample program that illustrates this. I've tried with various, compiler flags like -D_FILE_OFFSET_BITS=64 According to man 2 read, the maximum is limited by SSIZE_MAX which is defined in /usr/include/bits/posix1_lim.h # define SSIZE_MAX LONG_MAX And LONG_MAX is defined in /usr/include/limits.h as # if __WORDSIZE == 64 # define LONG_MAX 9223372036854775807L # else # define LONG_MAX 2147483647L # endif # define LONG_MIN (-LONG_MAX - 1L) Either this is a bug in the ubuntu buildsystem, or my build system is broken. Can anyone with a 64 try to run the above program.

[Bug target/40956] GCSE opportunity in if statement
--- Comment #3 from davidxl at gcc dot gnu dot org 2009-12-23 19:37 ---
This bug is ARM specific (thumb) mode. In x86, the hoisting is unnecessary as
the move instruction support the imm form.
The issue here is more in the GIMPLE canonicalization (target specific). In
this case, the IR should be in the following form to expose the hoisting.
if (...) {
temp = 0;
*p = temp;
}
else
{
temp = 0;
*(p+1) = temp;
}

When GCC supports C++ attributes you could get the diagnostics you want like
this:
class A_noconst [[base_check]] : public A {
...
};
class A_const [[base_check]] : public A {
...
};
c.f. http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2009/n2928.htm
As I said in bug 31397 c12 it would be better to implement those attributes
than to add warning switches

Compile the attached source code with options -Os -mthumb, gcc generates:

.L10:
ldr r1, [sp, #8]
add r3, r0, r1

Instruction A spills parameter into stack, it is always executed at the start
of the function, so it can be merged into the function prologue

[Bug c++/42488] New: spurious strict-aliasing warning
The following very simple program is giving me a warning with g++ 4.4.2 with
-Wall (or -Wstrict-aliasing=1, 2 or 3). I don't think it should be giving the
warning, so I think this is a bug.
Replacing std::complex with a simple user-defined complex-like class makes the
warning go away, so maybe there is a bug in the complex class?
Also, replacing the virtual inheritance with normal inheritance makes the
warning go away.
Likewise removing the A class and moving the virtual inheritance to C : virtual
public B.
Or if I make the argument of foo a reference.
===
#include complex
struct A {
virtual int value() const=0;
};
struct B : virtual public A {
bool isOne() const { return A::value() == 1; }
};
struct C : public B {
int value() const { return 1; }
};
struct D {
void foo(std::complexfloat x) const; // foo is extern
};
void callFoo()
{
C c;
D d;
if (c.isOne()) d.foo(0);
}
===
The warning produced is:
g++-4 -c -O2 -Wstrict-aliasing foo.cpp
foo.cpp: In function void callFoo():
foo.cpp:9: warning: dereferencing pointer anonymous does break
strict-aliasing rules
foo.cpp:9: note: initialized from here
This appears to me to be different from similar bugs: 41838, 39390 which
reference the same warning, but maybe it is related.

[Bug middle-end/42488] spurious strict-aliasing warning
--- Comment #4 from pinskia at gcc dot gnu dot org 2009-12-24 05:40 ---
Here is a reduced testcase without the include:
struct complex
{
complex(float b = 0.0, float c = 0.0) { __real__ a = b; __imag__ a = c; }
_Complex float a;
};
struct A {
virtual int value() const=0;
};
struct B : virtual public A {
bool isOne() const { return A::value() == 1; }
};
struct C : public B {
int value() const { return 1; }
};
struct D {
void foo(complex x) const;
};
void callFoo()
{
C c;
D d;
if (c.isOne()) d.foo(0);
}
CUT
Note making the complex a non-POD makes the warning go away.
Also it works on the trunk.

[Bug rtl-optimization/42388] [4.5 Regression] ICE in move_bb_info with sel-sched and modulo-sched for 176.gcc
--- Comment #3 from abel at gcc dot gnu dot org 2009-12-24 07:39 ---
The problem was that the failing assert is actually too strict, when an empty
block is removed, its predecessor could be outside the region. After fixing
this, I have also further robustified the function to expect empty blocks with
no succs or preds, as this problem showed itself yet another time via the
single failed test of the patch on ia64.
* sel-sched-ir.c (maybe_tidy_empty_bb): Do not delete empty blocks
that have no predecessors nor successors. Do not call move_bb_info
for empty blocks outside of current region.
