--- Comment #2 from r dot emrich at de dot tecosim dot com 2009-03-04 09:07 --- (In reply to comment #1) Huh. It's not even compiling. You're right. OTOH the sequence $ gcc -v -S hello.c $ gcc -v -c hello.s $ gcc -v -o hello hello.o builds correctly. Anyway the driver is broken for x86_64-pc-mingw32.

--- Comment #4 from rguenth at gcc dot gnu dot org 2009-03-04 15:21 ---
In TODO_recompute_alias after PRE we have something (alc_capture_mixer1, found
through DECL_INITIAL of caps) in gimple_addressable_vars that is no longer
available.
Honza, this is yours again. I guess during inlining we no longer add
referenced vars to the inlined-to function if they are addresses of globals
referenced through initializers of local statics?
static struct snd_kcontrol_new alc_capture_mixer1[];
static void set_capture_mixer(struct alc_spec *spec)
{
static struct snd_kcontrol_new *caps[3] = {
alc_capture_mixer1,
alc_capture_mixer2,
alc_capture_mixer3,
};
if (spec-num_adc_nids 0 spec-num_adc_nids = 3)
spec-cap_mixer = caps[spec-num_adc_nids - 1];
}
inlined into some other function. Proper testcase still reducing.

[Bug c++/39364] New: Arithmetic on bool bit-fields is incorrect
Bug #30274 bool bit-field: wrong increment and decrement is supposedly fixed
in 4.2.0 and 4.3.0.
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30274
However, the underlying issue still reproduces in several ways with GCC 4.2.4
and 4.3.2.
#include stdio.h
struct S {
bool f : 7;
};
struct S v = { 2 };
struct S w = { true };
int main() {
printf(FAIL: %d is not 1\n, (int)v.f);
w.f *= 3;
printf(FAIL: %d is not 1\n, (int)w.f);
return 0;
}
% g++ test.cc ; ./a.out
FAIL: 2 is not 1
FAIL: 3 is not 1
Also fails with gcc -std=c99.

[Bug c++/39365] New: ++ operator with volatile bool increments
This program:
extern C void abort();
typedef volatile bool my_bool;
int main()
{
my_bool b = false;
int i;
b++;
b++;
i = b;
if (i != 1)
abort ();
return 0;
}
calls abort(), because GCC is generating an increment for the '++' operator
rather than setting the value to true, and so 'i' becomes 2 not 1.
This is an exact duplicate of bug #29295, except that I've added the keyword
volatile on line 2, and this program still aborts on 4.2.4 and 4.3.2, even
though bug #29295 is supposedly fixed in those versions.

[Bug libstdc++/39366] New: Memory Leak in Exception Handling
When an exception is thrown for the first time in a given thread, there is a 16 bytes memory leak if the thread is started by a C++ library loaded using dlopen() by a C executable. The key factors to reproduce the leak are: - The executable must be a C program not linked against libstdc++ and not linked against the faulty C++ library; - The C++ library must be loaded using dlopen(); - A leak will occur the first time a thread started by the C++ library throws an exception. The problem was not present in libstdc++ 6.0.3 (distributed with GCC 3.4.6), but is present in libstdc++ 6.0.9 and libstdc++ 6.0.10. Attached is a gzip-compressed tarball containing: - main.c: The source file for the executable; dummy.cpp: The source file for the C++ library; build.sh: The bash shell script used to compile; main.i, main.ii: The preprocessed outputs. Command line to compile: cd /cpp_exception_test; ./build.sh testlib.so Example command line to execute: cd /cpp_exception_test; ./cpp_exception_test /cpp_exception_test 10 Note that Valgrind reports an 8 bytes leak per thread throwing a first exception, but the memory growth seen when running a large number of iterations is 16 bytes.

[Bug libstdc++/39366] Memory Leak in Exception Handling
--- Comment #2 from pinskia at gcc dot gnu dot org 2009-03-04 20:14 ---
It looks like glibc is not clearing up dlopened TLS allocated memory.
A simple testcase for glibc would be put into a shared library something like:
__thread int a;
int f(void)
{
return a;
}
--- CUT ---
And then call dlopen that library and see what happens with calling f from the
thread.
If that does not leak, try adding that creating a shared that contains a
function which just calls f and then call that new function from the thread.
Thanks,
Andrew Pinski

[Bug debug/39368] New: loc_descriptor doesn't call delegitimize_address on MEMs
For a RISC target that doesn't allow memory-indirect addressing, the proper way to represent an access of a symbol found in the GOT is to first load the symbol from the GOT into a register, and then use that register for memory access or call as needed. For proper scheduling and instruction selection, the symbol load source should be represented as what it is, i.e. a MEM. So we have a (MEM (unspec ... UNSPEC_GOT)) . For the purposes of debug output, this should be translated back into the symbol_ref it represents. However, loc_descriptor looks only into the address inside a MEM, it does not process the entire mem with targetm.delegitimize_address. I.e. there is no way to get rid of the MEM if it is not nested in another MEM. -- Summary: loc_descriptor doesn't call delegitimize_address on MEMs Product: gcc Version: 4.4.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: debug AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: amylaar at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39368

gcc is latest svn build by gcc 4.3.3, platform is mingw current/stable on vista
current sp1.
any hint is appreciated.
similar behavior of instability on SSE optimizations occurs also in v 4.3.3,
not in 3.4
options are typical -O3 -march=core2 or -O3 -msse,2,3, -g or not.

[Bug target/39361] [4.4 Regression] Many new neon test failures
--- Comment #2 from hubicka at gcc dot gnu dot org 2009-03-05 02:04 --- I specifically kept the code propagating TREE_READONLY arguments so const arguments will get constant propagated at -O0. But I see the propagation is disabled for SSA registers. I am testing patch for this... I guess we need only constant propagation and not copy propagation, right? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39361

--- Comment #6 from hubicka at gcc dot gnu dot org 2009-03-05 02:09 --- This is curious, since we should see the initializer when adding variable at first time. I am looking into this. Honza -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39360
