[Bug middle-end/34454] New: [4.3 regression] Overflow check is optimized away when -O2 is enabled
Testcase :
#include
#include
void foo(ssize_t x)
{
if (x >= 0) {
if (x+x < 0) printf("Overflow\n");
}
}
main()
{
volatile ssize_t x =2147483647;
foo(x);
}
When compiled with -O2 it doesn't print Overflow, if you omit -O2 it prints
overflow.
gcc 3.4.6 works fine so this is a regression.

Attached is a better patch which adds -f{no}-show-error-count and uses it in
regression tests so regtests works now. IDE's also can use this option.
Is it possible to get this in for gcc 4.3 or gcc 4.4?

[Bug middle-end/34843] New: Missing overflow diagnostic for Python 2.5's unicodeobject.c
unicodeobject.c from Python 2.5 assumes signed integer overflow in the
following code in unicode_expandtabs function :
i and j are signed integers (defined as ssize_t) :
[...]
else {
j++;
if (*p == '\n' || *p == '\r') {
i += j; <=== Possible overflow
old_j = j = 0;
if (i < 0) { <== Code won't work due to undefined overflow
PyErr_SetString(PyExc_OverflowError,
"new string is too long");
return NULL;
}
}
}
[...]
Now if I compile this file with -O3 -Wstrict-overflow=3 I got no warning
although undefined overflow occurs and code is miscompiled unless -fwrapv is
specified. I think gcc should be warning us here about undefined overflow.

[Bug c/34841] 'make check' of libsndfile-1.0.17 fails with gcc-4.2.2 -O2 optimization, OK with -O1 one
--- Comment #9 from ismail at pardus dot org dot tr 2008-01-18 02:45

File lossy_comp_test.c starting line 761 :
sum_abs = abs (sum_abs + abs (abs (data [k]) - 256)) ;
if (sum_abs < 1.0)
{
printf ("\n\nLine %d: Signal is all zeros (%d, 0x%X).\n", __LINE__, sum_abs,
sum_abs) ;
exit (1) ;
} ;
sum_abs gets a value of -27260928 . Making sum_abs unsigned fixes the problem.

[Bug c/34841] 'make check' of libsndfile-1.0.17 fails with gcc-4.2.2 -O2 optimization, OK with -O1 one
--- Comment #11 from ismail at pardus dot org dot tr 2008-01-18 03:10 --- Actually the only bug here is that -Wstrict-overflow should issue a warning for that line. About the dependency on optimization level, signed integer overflow is undefined in C standard so its not a good idea to depend on it. What GCC does is exploiting this fact for optimizations which is fine. What -fwrapv does that it defines wrapping for signed integer overflow. I hope this makes the issue more clear. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34841
