[Bug c++/31596] New: Internal compiler error (Segmentation fault)
Dear all,

We use the compiler to generate code for a PowerPC processor.

void f (const XXXint,char p1, const XXXbool,int p2)

}
The compiler crashes with the following message:

[Bug tree-optimization/31602] New: Overflow warning causes GDB -Werror build failure
GCC HEAD now warns about this testcase for mips-linux, reduced from
gdb/value.c. Compile with -O2 -Wall:
extern int foo();
int show_values (void)
{
int i;
static int num;
if (num = 0)
num = 1;
for (i = num; i num + 10; i++)
foo();
return i;
}
overflow.c:10: warning: assuming signed overflow does not occur when assuming
that (X + c) = X is always true
I think that the problem arises when we assume that the loop is executed at
least once; the initial condition is num num + 10. However the warning does
not arise if num is an argument to the function instead of a static variable.
Unfortunately the warning appears to be correct. I say unfortunately because
there's no apparent way to avoid the warning - which sounds more like -Wextra
to -Wall. Does this this example contradict the easy to avoid statement in
the -Wstrict-overflow=1 documentation?

[Bug tree-optimization/31605] New: VRP eliminates a useful test due to overflow
Most floating point tests fail when GDB is built with GCC trunk for mips-linux.
I assume it shows up on all targets. The miscompiled function is
doublest.c:put_field. Here is a reduced test case:
int put_field (unsigned int start, unsigned int len)
{
int cur_bitshift = ((start + len) % 8) - 8;
if (cur_bitshift -8)
not_removed ();
}
When compiled with -O2, the resulting assembly file does not include a call to
not_removed. But in fact it should be called in seven out of eight cases.
((start + len) % 8) is an unsigned int in [0, 7]. ((start + len) % 8) - 8 is
an unsigned int in [UINT_MAX - 8, UINT_MAX]. cur_bitshift is an int, which can
not represent UINT_MAX; this is an implementation defined conversion, and the
GCC manual says that the value is reduced modulo (UINT_MAX+1) until it fits in
the range of int. So the defined result of the conversion is in [-8, -1].
But VRP says:
Value ranges after VRP:
start_1(D): VARYING
len_2(D): VARYING
D.1559_3: [0, +INF] EQUIVALENCES: { } (0 elements)
D.1560_4: [0, 7] EQUIVALENCES: { } (0 elements)
D.1561_5: [4294967288, +INF] EQUIVALENCES: { } (0 elements)
cur_bitshift_6: [-INF(OVF), -2147483648] EQUIVALENCES: { } (0 elements)
Folding predicate cur_bitshift_6 = -7 to 0
Removing basic block 3
Merging blocks 2 and 4
put_field (start, len)
{
int cur_bitshift;
unsigned int D.1561;
unsigned int D.1560;
unsigned int D.1559;
bb 2:
D.1559_3 = start_1(D) + len_2(D);
D.1560_4 = D.1559_3 7;

--- Comment #1 from pinskia at gcc dot gnu dot org 2007-04-17 15:03 --- The page is not blank for me: 5.26 Attribute Syntax This section describes the syntax with which __attribute__ may be used, and the constructs to which attribute specifiers bind, for the C language. Some details may vary for C++ and Objective-C. Because of infelicities in the grammar for attributes, some forms described here may not be successfully parsed in all cases. There are some problems with the semantics of attributes in C++. For example, there are no manglings for attributes, although they may affect code generation, so problems may arise when attributed types are used in conjunction with templates or overloading. Similarly, typeid does not distinguish between types with different attributes. Support for attributes in C++ may be restricted in future to attributes on declarations only, but not on nested declarators. cut - I wonder if you just accessed it while the page was being regenerated. -- pinskia at gcc dot gnu dot org changed: What|Removed |Added Status|UNCONFIRMED |WAITING Component|c |web http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31599

[Bug testsuite/31589] gcc.dg/vect failures due to missing target specifiers
--- Comment #2 from dorit at il dot ibm dot com 2007-04-17 20:10 ---
2 more are under investigation:
no-section-anchors-vect-69.c
vect-reduc-dot-u16a.c
In the first testcase, the vectorizer can only prove that the data reference in
the third loop is aligned on 8 bytes. This is enough for targets like ia64 in
which the vector size is 8 bytes, and therefore we don't need to peel in order
to force alignment for this loop. So overall in this testcase we peel only
twice. On targets that require 16byte alignment, a guaranteed 8bytes alignment
is not enough, and therefore we peel this loop to align the data-reference (and
overall in the testcase we peel 3 times).
I guess the way to solve this is to add a keyword that lists the targets with
8byte-wide-vectors and targets with 16byte-wide-vectors, or just hard code the
targets that are expected to fail/pass here. I'll sleep on it and supply a
patch soon.
The second test needs the same fix as a lot of the other tests:
add { target vect_pack_mod } to the check. This is because the loop in main
has a cast from int to short in it. However, in this testcase we already have
two target keywords that we are checking:
{ target { vect_short_mult vect_widen_sum_hi_to_si } },
and I don't think the testsuite engine currently provides the flexibility to
and a third keyword, so I suggest to just change the loop slightly to avoid the
cast (it's not the point of this testcase anyway):

--- Comment #4 from pinskia at gcc dot gnu dot org 2007-04-17 20:27 ---
And it is a bug on the 4.2 branch.
Before Ian's patch we got the following ranges for the testcase in comment #2:
D.1528_1: VARYING
start_2: VARYING
D.1528_3: VARYING
cur_bitshift_4: ~[0, 0] EQUIVALENCES: { } (0 elements)
start_5: [0, 0fff8] EQUIVALENCES: { start_2 } (1 elements)
retval_6: VARYING
start_9: [0fff9, +INF] EQUIVALENCES: { start_2 } (1 elements)
After we get:
D.1528_1: VARYING
start_2: VARYING
D.1528_3: VARYING
cur_bitshift_4: [-INF(OVF), -2147483648] EQUIVALENCES: { } (0 elements)
start_5: [0, 0fff8] EQUIVALENCES: { start_2 } (1 elements)
retval_6: VARYING
start_9: [0fff9, +INF] EQUIVALENCES: { start_2 } (1 elements)
Before:
Visiting statement:
cur_bitshift_4 = (int) start_9;
Found new range for cur_bitshift_4: ~[0, 0]
After:
Visiting statement:
cur_bitshift_4 = (int) start_9;
Found new range for cur_bitshift_4: [-INF(OVF), -2147483648]
That is just incorrect.

[Bug fortran/31551] ice in fold_convert, at fold-const.c:2330
--- Comment #7 from zingale at gmail dot com 2007-04-17 21:32 --- I am seeing internal compiler error: in fold_convert, at fold-const.c:2330 using gcc version 4.3.0 20070417 (experimental) If I follow the thread in this bug list, it seems that this version should have the patch applied. So I am not sure if I am not testing a patched version or if there is still an ICE there. FWIW, this code used to compile just fine with gfortran up until a month ago. Sadly, I can't seem to distill this down into a simple test case. gfortran -Jt/Linux.gfortran.debug/m -I t/Linux.gfortran.debug/m -g -fno-range-check -I ../../extern/helmeos -c -o t/Linux.gfortran.debug/o/boxarray.o ../../boxlib/boxarray.f90 ../../boxlib/boxarray.f90: In function boxarray_build_l: ../../boxlib/boxarray.f90:297: internal compiler error: in fold_convert, at fold-const.c:2330 Please submit a full bug report, with preprocessed source if appropriate.

That's right. Daniel, could you confirm that your testcase is indeed fixed with today's mainline? Sadly, I can't seem to distill this down into a simple test case. Even if it's not that small, could you send it to my privately? (fxcoudert at gcc dot gnu dot org) Make a tarball of the source file and instructions on how to build it, and I'll reduce it. -- fxcoudert at gcc dot gnu dot org changed: What|Removed |Added CC||zingale at gmail dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31551
