[Bug rtl-optimization/57662] [4.9 Regression] ICE: SIGSEGV in code_motion_process_successors with -fschedule-insns2 -fselective-scheduling2
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57662 --- Comment #6 from Andrey Belevantsev abel at gcc dot gnu.org --- (In reply to Richard Biener from comment #5) Fixed according to 2013-08-14 Andrey Belevantsev a...@ispras.ru PR rtl-optimization/57662 * sel-sched.c (code_motion_process_successors): When the current insn is removed after the recursive traversal, break from the loop. Add comments and debug printouts. (?) Yes. Sorry, I keep forgetting that the post-commit Bugzilla autoupdate no longer works so I didn't look at the PR after committing.
[Bug rtl-optimization/58295] [4.8/4.9 regression] Missed zero-extension elimination in the combiner
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58295 --- Comment #11 from Eric Botcazou ebotcazou at gcc dot gnu.org --- So why don't reject it at TARGET_LEGITIMATE_COMBINED_INSN/ix86_legitimate_combined_insn instead of limit at combine phase if it's only benefit for x86 ? The question sounds self-contradictory... Anyway, rather than inventing a new hook for each problem, let's try to formulate it in terms of existing hooks.

So, is it make's issue? (GNU Make 3.81) I'm in a maze.

[Bug sanitizer/58937] New: Preloaded libasan segfaults on unsanitized executables
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58937
Bug ID: 58937
Summary: Preloaded libasan segfaults on unsanitized executables
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: sanitizer
Assignee: unassigned at gcc dot gnu.org
Reporter: y.gribov at samsung dot com
CC: dodji at gcc dot gnu.org, dvyukov at gcc dot gnu.org,
e.gavrin at samsung dot com, jakub at gcc dot gnu.org,
kcc at gcc dot gnu.org
My system has a mix of sanitized and unsanitized executables and libs calling
each other in a complex manner. I've recently tried doing a global
LD_PRELOAD=libasan to make sure I don't have problems with initialization order
outlined in #56393.
I quickly ran into a problem which is reproduced in the attach. Here is the gdb
session log:
$ /home/ygribov/install/gcc-master/bin/gcc -g main.i
$ ./a.out
$ LD_PRELOAD=~/install/gcc-master/lib64/libasan.so.0 ./a.out
Segmentation fault (core dumped)
$ gdb a.out
(gdb) set env LD_PRELOAD /home/ygribov/install/gcc-master/lib64/libasan.so.0
(gdb) b __asan_init_v1
(gdb) run
Program received signal SIGSEGV, Segmentation fault.
0x in ?? ()
(gdb) bt

(gdb) fr 1
#1 0x74e4fa62 in signal () at
/home/ygribov/gcc/gcc-master/libsanitizer/asan/asan_interceptors.cc:133
133return REAL(signal)(signum, handler);
(gdb) l
128#endif // ASAN_INTERCEPT_PTHREAD_CREATE
129
130#if ASAN_INTERCEPT_SIGNAL_AND_SIGACTION
131INTERCEPTOR(void*, signal, int signum, void *handler) {
132 if (!AsanInterceptsSignal(signum)) {
133return REAL(signal)(signum, handler);
134 }
135 return 0;
136}
137
It seems that current libasan currently relies on sanitized code to call
__asan_init. If we preload it into an unsanitized executable, it will remain
uninitialized and will segfault on every REAL(whatever) call.
IMHO ability to do global LD_PRELOAD for all executables in the system is
rather useful so I think it makes sense to support this usage scenario. What
about adding a ctor to call __asan_init in libasan itself?
Note that this error should repro in Clang (on platforms that use dynamic
linking).

This is a regression, because a more specific _GLIBCXX_ATOMIC_BUILTINS_4 was
defined (but is no longer available) and now there is defined
ATOMIC_INT_LOCK_FREE=1 (I think think the definition is correct, because there
were available _GLIBCXX_ATOMIC_BUILTINS_{1,2,4} and no
_GLIBCXX_ATOMIC_BUILTINS_8).
The other thing is, std::exception_ptr availability should not depend on the
fact whether the platform has lock-free atomics or not.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58938
--- Comment #6 from Jonathan Wakely redi at gcc dot gnu.org ---
(In reply to Rafał Rawicki from comment #3)
This is a regression, because a more specific _GLIBCXX_ATOMIC_BUILTINS_4 was
defined (but is no longer available) and now there is defined
ATOMIC_INT_LOCK_FREE=1 (I think think the definition is correct, because
there were available _GLIBCXX_ATOMIC_BUILTINS_{1,2,4} and no
_GLIBCXX_ATOMIC_BUILTINS_8).
But ATOMIC_INT_LOCK_FREE only refers to int, i.e. 4-byte integer, so if
_GLIBCXX_ATOMIC_BUILTINS_4 was defined then I would expect atomic ops on int to
always be lock-free, i.e. the macro should be defined to 2. It's independent
of whether atomic ops for 8-byte types are supported.
The other thing is, std::exception_ptr availability should not depend on the
fact whether the platform has lock-free atomics or not.
Without them you either need libatomic.so or you risk undefined behaviour such
as leaking exception objects or worse, dangling references to destroyed
exceptions.

yes. if an integer_type_node is 4 bytes, and the architecture has a 4 byte
compare and swap, it should be set to 2 regardless of the lack of an 8 byte
lock free operation.
this assert should never fail:
if (__atomic_always_lock_free(4, NULL) (sizeof(int) == 4))
assert (ATOMIC_INT_LOCK_FREE == 2);
In theory _GLIBCXX_ATOMIC_BUILTINS_4 should have been the same as
ATOMIC_INT_LOCK_FREE as long as sizeof (int) == 4
The other thing is, std::exception_ptr availability should not depend on the
fact whether the platform has lock-free atomics or not.
Without them you either need libatomic.so or you risk undefined behaviour

[Bug libstdc++/58929] condition_variable does not wait without -pthread
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58929 --- Comment #3 from Johan Lundberg lundberj at gmail dot com --- (In reply to Jonathan Wakely from comment #2) I suppose we could turn all timed waiting functions into sleeps, and wait() into an infinite loop, when libpthread is not linked in, but I'd prefer not to add that complexity. I agree, that sounds too much. The documentation of -pthread states that it sets flags for the preprocessor in addition to the linker and at least on my system, _REENTRANT is set by -pthreads. If that's a canonical way to detect threading support I suggest checking it in the headers that rely on threading: #ifndef _REENTRANT #error No thread support enabled. #endif If there are reasons this is not a good idea so be it.

Patch to simplify atomic_compare_and_swapdwi_doubleword pattern
Currently, gcc generates lots of unnecessary moves for following testcase
(actually gcc.dg/atomic-store-6.c):
--cut here--
__int128_t i;
int main()
{
__atomic_store_16(i, -1, 0);
if (i != -1)
__builtin_abort();
return 0;
}
--cut here--
gcc -O2 -mcx16:
movqi(%rip), %rsi
movq$-1, %rcx
movqi+8(%rip), %rdi
.L2:

movq%rdi, %rdx
movq%rcx, %rbx
lock cmpxchg16b i(%rip)
movq%rdx, %rdi
movq%rax, %rsi
jne .L2
I have experimented with sync x86_64 pattern, to see if we can simplify
atomic_compare_and_swapdwi_doubleword pattern, so it would work with real
doublemode values and this way remove unnecessary register moves. However, I
have hit an ICE in assing_by_spills that prevents me from using these
simplifications:
gcc -O2 -mcx16

I believe that the pattern is correct, and LRA is tripping on some

[Bug c/58943] wrong calculation of indirect structure member arithmetic via function call
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58943 Mikael Pettersson mikpelinux at gmail dot com changed: What|Removed |Added CC||mikpelinux at gmail dot com --- Comment #1 from Mikael Pettersson mikpelinux at gmail dot com --- Created attachment 31127 -- http://gcc.gnu.org/bugzilla/attachment.cgi?id=31127action=edit reduced test case I believe this bug is real, and a dup or variation of PR48814, the difference being that PR48814 had a postfix ++ while here we have a compound assignment (|=). According to Joseph's comment in http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48814#c8 the same interleaving restrictions apply to ++ and |=. The bug appears to trigger when the lvalue is a non-scalar. It doesn't have to be a struct member, an array element (as in this test case) suffices.

Yes I expected failures to happen in reassoc due it not being well tested before and now my patch is forcing the path inside reassoc being a lot more than before. Most likely you could get a test case that exposes this before my patch.
[Bug bootstrap/58949] New: libcilkrts will not bootstrap on x86_64 without libstdc++.i686 32 bit libraries installed
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58949 Bug ID: 58949 Summary: libcilkrts will not bootstrap on x86_64 without libstdc++.i686 32 bit libraries installed Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: bootstrap Assignee: unassigned at gcc dot gnu.org Reporter: amacleod at redhat dot com on x86_64-unknown-linux-gnu bootstrap fails during configuration of libcilkrts. When testing for a functioning c++ compiler, the executable builds fine, but fails to execute because the executable is looking for the 32 bit system library at some point instead of using the local libraries built by the toolchain. You should be able to reproduce this by bootstrapping on an x86_64 box which does not have libstdc++.i686 installed. When I installed libstdc++.i686 on my system the problem went away...

Will think about it tomorrow.
