[Bug middle-end/56077] [4.6/4.7 Regression] volatile ignored when function inlined
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56077 --- Comment #16 from Andrey Belevantsev abel at gcc dot gnu.org 2013-04-11 06:17:41 UTC --- The patch adds more pending list flushes and thus more dependencies. So by itself it is conservative and should not result in correctness issues that arise when the scheduler gets more freedom. However, the accidental change that the patch reverted was made back in 2008. Since then, obviously many changes were made to the scheduler, and some of those could assume that pending lists are flushed on jumps only. One such iasue has surfaced immediately on 4.6/4.7, where the patch was reverted, but on 4.8 and trunk that was fixed by Maxim's patch. PR 56912 is another issue judging from the backtrace. I will take a look there as soon as the testcase shows up. Overall, I agree with Jakub -- the patch fixes wrong code (though not very important one as the bug was reported in 4.5 years after the change was made), it is conservative, but has some fallout, so for 4.6/4.7 let's wait more until all issues come up, and for 4.8 let's just fix the issues.

[Bug c/56917] New: -ftrapv detects a overflow wrongly.
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56917
Bug #: 56917
Summary: -ftrapv detects a overflow wrongly.
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: a...@fsij.org
Created attachment 29855
-- http://gcc.gnu.org/bugzilla/attachment.cgi?id=29855
steps to reproduce the -ftrapv problem
I found that following program aborts with -ftrapv with gcc-4.8.0 on
Debian GNU/Linux (x86_64).
% cat tst.c
unsigned long ul = 0x8000UL;
int main(int argc, char *argv[])
{
long l;
l = (-(long)(ul-1))-1;
return 0;
}
% /home/src/gcc/bin/gcc -g -ftrapv -Wall tst.c
tst.c: In function 'main':
tst.c:5:8: warning: variable 'l' set but not used [-Wunused-but-set-variable]
long l;
^
% ./a.out
zsh: abort (core dumped) ./a.out
I think it should not abort on x86_64.
Since ul is LONG_MAX+1 (in indefinite precision), ul-1 is LONG_MAX which is
representable in long.
So the cast, (long)(ul-1), doesn't change the value.
Its negation, -(long)(ul-1), is -LONG_MAX which is also representable in long.
Its predecessor, (-(long)(ul-1))-1, is -LONG_MAX-1 = LONG_MIN which is also
representable in long.

[Bug tree-optimization/56918] New: incorrect auto-vectorization of array initialization
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56918
Bug #: 56918
Summary: incorrect auto-vectorization of array initialization
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: kr...@kde.org
Compile the following testcase with gcc -m32 -O2 -ftree-vectorize -msse2
int main() {
double data[4];
for (int i = 0; i 2 * 2; ++i) {
data[i] = ((i + 2) % 3) + 1;
}
if (data[0] != 3.) {
return 1;
}
return 0;
}
The first for-loop calculates the values 6, 7, 8, 9 instead of the expected 3,
1, 2, 3.

-fno-builtin-XXX does not prevent GCC from emitting calls to XXX. It only
makes GCC not assume anything about existing calls to XXX.
For example to avoid transforming printf to puts in
extern int printf(const char *, ...);
int main()
{
printf (Hello World\n);
return 0;
}
it does not work to specify -fno-builtin-puts, but instead you need to
provide -fno-builtin-printf.
Note that -fno-builtin only prevents the C family parsers from recognizing
XXX as builtin decls. The fact that -fno-builtin was specified or not
cannot be queried in any way from the middle-end.
I consider the inability to specify this to the GCC middle-end as bug
but I am not going to work on it. The requirement to be able to
generate calls to memset. memcpy and memmove is deep-rooted into
code-expansion as well for aggregate init and assignment.

The vectorizer does nothing wrong. The bug goes away with -fdisable-tree-vrp2
which would expose
- stmp_var_.3_2 = 0 + 1;
- stmp_var_.3_19 = stmp_var_.3_2 + 1;
- stmp_var_.3_20 = stmp_var_.3_19 + 1;
- vect_cst_.4_21 = {0, stmp_var_.3_2, stmp_var_.3_19, stmp_var_.3_20};
+ stmp_var_.3_2 = 1;
+ stmp_var_.3_19 = 2;
+ stmp_var_.3_20 = 3;
+ vect_cst_.4_21 = { 0, 1, 2, 3 };
(ick, unfolded 0 + 1)
so we expand
vect_patt.11_29 = { 2, 3, 4, 5 } 31;
vect_patt.12_30 = { -1, -1, -1, -1 } - vect_patt.11_29;
vect_patt.13_32 = vect_patt.12_30 * { 3, 3, 3, 3 };
vect_patt.15_33 = { 2, 3, 4, 5 } - vect_patt.13_32;
vect_var_.16_35 = vect_patt.15_33 + { 1, 1, 1, 1 };
vect_var_.18_36 = [vec_unpack_float_lo_expr] vect_var_.16_35;
vect_var_.18_37 = [vec_unpack_float_hi_expr] vect_var_.16_35;
MEM[(double[1024] *)data] = vect_var_.18_36;
MEM[(double[1024] *)data + 16B] = vect_var_.18_37;
_10 = data[0];
if (_10 != 3.0e+0)
where I bet that unfolded constant expressions are somehow mis-handled.
[Bug fortran/56919] New: [4.6/4.7/4.8/4.9 Regression] Wrong result for SYSTEM_CLOCK on Cygwin

Note that Cygwin not only defines CLOCK_MONOTONIC but since Cygwin-1.7.6 also _POSIX_MONOTONIC_CLOCK 200112L [1]. Thus, _POSIX_MONOTONIC_CLOCK [2] can also not be used. Currently, libgfortran uses (cf.libgfortran/intrinsics/system_clock.c): /* POSIX states that CLOCK_REALTIME must be present if clock_gettime is available, others are optional. */ #ifdef CLOCK_MONOTONIC #define GF_CLOCK_MONOTONIC CLOCK_MONOTONIC #else #define GF_CLOCK_MONOTONIC CLOCK_REALTIME #endif #ifdef HAVE_CLOCK_GETTIME err = clock_gettime (GF_CLOCK_MONOTONIC, ts); #else #if defined(HAVE_CLOCK_GETTIME_LIBRT) SUPPORTS_WEAK GTHREAD_USE_WEAK if (weak_gettime) err = clock_gettime (GF_CLOCK_MONOTONIC, ts); #endif err = gf_gettime (secs, nanosecs); #endif And gf_gettime (time_1.h) uses: gettimeofday - or if not available: clock_gettime (CLOCK_REALTIME - or a simple time(NULL). Nick suggests to simply call gf_gettime unconditionally.

[Bug tree-optimization/56920] New: another static initialization of an array miscompiled

Bug #: 56920
Summary: another static initialization of an array miscompiled
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: kr...@kde.org
compile the following testcase with gcc -O3 -msse2:
int main() {
unsigned int indexes[15];
for (unsigned int i = 0; i 15; ++i) {
indexes[i] = (i * 2) % 15;
}
for (unsigned int i = 0; i 15; ++i) {
if (indexes[i] != (i * 2) % 15) {
__builtin_abort();
}
}
}
GCC initializes the stack with the values 0, 2, 4, 6, 8, 10, 12, 14, 16, 18,
20, 22. The last three values of indexes apparently are not initialized at all.
Expected is: 0, 2, 4, 6, 8, 10, 12, 14, 1, 3, 5, 7, 9, 11, 13
This might be related to #56918, but -fdisable-tree-vrp2 does not fix the
issue.
