[Bug c++/35078] New: ICE with reference in parallel for loop
The following invalid code snippet triggers an ICE since GCC 4.2.0
when compiled with -fopenmp:
===
templateint void foo()
{
#pragma omp parallel for
for (int i = 0; i 10; ++i)
;
}
===
bug.cc: In function 'void foo()':
bug.cc:5: internal compiler error: in build_modify_expr, at cp/typeck.c:5809

Without templates the situation is not much better:
===
void foo()
{
int j = 0;
#pragma omp parallel for
for (int i = j; i 10; ++i)
;
}
===
bug.cc: In function 'void foo()':
bug.cc:6: error: 'i' declared as reference but not initialized
bug.cc:7: internal compiler error: in build_modify_expr, at cp/typeck.c:5809
Please submit a full bug report, [etc.]
The compiler issues a bogus error message (the variable is initialized),
and crashes afterwards.

[Bug java/35035] [4.3 Regression] Has any one managed to run the libjava test suite on powerpc-apple-darwin9?
--- Comment #30 from howarth at nitro dot med dot uc dot edu 2008-02-04 14:54 --- With regard to the 64-bit support for powerpc-apple-darwin9, this does exist in Apple's open source release of libffi from PyObjC. Bill Bumgarner at Apple had the following comments on the issue of porting the changes from their open source release... http://www.opensource.apple.com/darwinsource/10.5/libffi-10/ into FSF gcc... So... long story short. About 10 years ago, PyObjC forked libffi for use in the PyObjC project. I don't remember exactly why it was forked, but forked it was. The PyOBjC version of libffi has been maintained over the years, specifically targeted to Mac OS X. In the past year, it got quite a bit of attention both to support the 64 bit variants of Mac OS X and quite a bit of cleanup work (new testing infrastructure, man pages, etc.etc.etc). It also grew an Xcode project. I would be perfectly happy to see all the changes folded back into the FSF/GCC community version (as long as the license remains liberal -- but we can fork it at the point of change, if it ever changes) and no longer have a forked version for PyObjC. But none of us have the time to fold together the decade+ of forked development.At this point, the most likely path forward is to drop the PyObjC version of FFI back into the PyObjC repository. It will, at least, be widely accessible again. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35035

Ok, I bootstrapped with revision 132091. The patched compiler ICE's on the
following test case:
typedef float TFtype __attribute__ ((mode (TF)));
TFtype
divtc3 (TFtype a, TFtype b)
{
if (__builtin_fabsl (a) __builtin_fabsl (b))
{
return a;
}
return b;
}
Here's a backtrace from the non debug build:

Really reduced testcase, the key is that pthread_mutex_t is a union:
typedef union
{
int __lock;
} pthread_mutex_t;
extern void abort (void);
int main(int c, char **v)
{
struct { int c; pthread_mutex_t m; } r = { .m = 0 };
if (r.c != 0)
abort ();
return 0;
}
in practice the testcase doesn't abort because the stack is zeroed anyway.

Uh, and we fold ABS x != 0.0 to x != 0.0, which makes the testcase
uninteresting as well. Also it happens that for double we succeed with
generating the nojump variant. And I don't have a cross with long-double
enabled appearantly. So, _possibly_ better testcase :)
extern long double fabsl(double);
extern void abort(void);
long double zero = 0.0L;
void __attribute__((noinline)) foo(long double x)
{
if (fabsl (x) != zero)

return -1;
return n / UNITS_PER_WORD;
}
and get 1 vs. 2 for the struct case. So, giving up in the above case
is certainly more correct.
Testing the obvious patch.

[Bug middle-end/29864] Folding conversion unsigned long long to float
--- Comment #2 from rguenth at gcc dot gnu dot org 2008-02-04 15:52 ---
A testcase would probably be sth along the lines of
extern void abort (void);
void __attribute__((noinline)) foo (unsigned long long x)
{
float uf = x;
float sf = (signed long long)x;
if (uf == sf)
abort ();
}
int main()
{
foo (-1);
return 0;
}
with the right target and soft-float (any suggestion?).

--- Comment #7 from rguenth at gcc dot gnu dot org 2008-02-04 16:40 --- The C++ standard says: 'The constant-expression may be larger than the number of bits in the object representation of the bit-field's type' in such cases the extra bits are used as padding bits and do not participate in the value representation' the rest (alignment, etc.) is implementation defined, thus defered to the ABI. Here actually at least gcc and icc agree in implementation as does the C++ ABI (2.4 II 1b, http://www.codesourcery.com/cxx-abi/abi.html#layout).

[Bug middle-end/33631] [4.1/4.2/4.3 Regression] auto structure not initialized correctly
--- Comment #2 from rguenth at gcc dot gnu dot org 2008-02-04 17:04 ---
The warning persists for me on the trunk, and the initialization is not done:
main (c, v)
{
int D.2713;
int D.2714;
int j[3];
typedef struct
{
int c;
int * j;
union pthread_mutex_t m;
} struct struct
{
int c;
int * j;
union pthread_mutex_t m;
};
struct
{
int c;
int * j;
union pthread_mutex_t m;
} r;
r.j = j;
r.m.__data.__lock = 0;
r.m.__data.__count = 0;
r.m.__data.__owner = 0;
r.m.__data.__nusers = 0;
r.m.__data.__kind = 0;
r.m.__data.__spins = 0;
r.m.__data.__list.__prev = 0B;
r.m.__data.__list.__next = 0B;
D.2713 = r.c;
printf (current should be zero but is %d\n[0], D.2713);
D.2714 = 0;
return D.2714;
}
This worked in 4.0.3 and 4.1.1 which generated
r = {};
r.j = j;
D.1158 = r.c;
So, this is likely a middle-end/gimplification issue (again).
Reduced testcase:
typedef struct __pthread_internal_list
{
void *__prev;
void *__next;
} __pthread_list_t;
typedef union
{
struct __pthread_mutex_s
{
int __lock;
unsigned int __count;
int __owner;
unsigned int __nusers;
int __kind;
int __spins;
__pthread_list_t __list;
} __data;
char __size[40];
long int __align;
} pthread_mutex_t;
extern int printf (__const char *__restrict __format, ...);
int main(int c, char **v)
{
int j[3];
struct { int c, *j; pthread_mutex_t m; } r = {
.j = j, .m = { { 0, 0, 0, 0, 0, 0, { 0, 0 } } },
};
printf(current should be zero but is %d\n, r.c);
return 0;
}

[Bug c/35069] Casting from a volatile type to a non-volatile type should cause a warning
--- Comment #2 from gcc-david at tulloh dot id dot au 2008-02-04 22:14

Yes, I didn't provide any context. I believe that this warning should apply
any time you are working with volatile variables.
A truncated real world example (kind of, real world debugging).
volatile static uint8_t OutputBuffer[4];
int16_t main(void) {
while(1) {
*(uint16_t *)(OutputBuffer)++;
}
}
ISR(PCINT0_vect) {
implement software SPI interface, transmit OutputBuffer in reverse byte
order.
}
