[Bug libgomp/35364] New: ICE on ia64 with vector declaration inside #pragma omp parallel
Overview
The following code fails to compile on ia64 platform with standard options. The
problem is gone when:
- removing the #pragma or
- declaring a double instead of a vector or
- not explicitly assigning a length to the vector
- inlining foo()
Problematic code:
=
#include
#include
class A {
void foo();
};
void A::foo() {
#pragma omp parallel
{
std::vector x(0);
}
}
Steps to reproduce
Compile using
g++ -Wall -fopenmp -save-temps -o ice.o -c ice.h
Build Date & Platform
=
Linux 2.4.21-27.0.4.EL #1 SMP ia64 GNU/Linux

later versions)

[Bug target/35365] New: dlopen fails because of missing _Jv_RegisterClasses under HP-UX 11.11
I build the DBD::mysql Perl module under HP-UX 11.11 on an RP3440 machine with GCC 4.2.1.

Apparently the problem is that the HP-UX dynamic linker does not just ignore unresolvable weak symbols as it should, so it's not a gcc bug, but perhaps the symbol should be exported by default, since the weak definition has already been removed for HP-UX in this patch: http://gcc.gnu.org/ml/gcc-patches/2006-04/msg00327.html -- Summary: dlopen fails because of missing _Jv_RegisterClasses under HP-UX 11.11 Product: gcc Version: 4.2.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: ams at toroid dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35365

But when the stream is synced it must be possible to mix char-by-char with wchar_t C stdio operations, which require a wide-character orientation of the stream, whereas, per C99 7.19.2, the orientation of a stream cannot be changed after opening. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35353

We can just split make check up into make check1 make check2 make check3 make check4 make check5 make check6 ... where the old "make check" is equivalent to make check[1-n] in terms of test coverage. This will allow make -j4 check to run make check1 make check2 make check3 make check4 all at the same time. This should speed things up greatly on current hardware. Seems simple enough: I feel a bit silly for not having thought of this before.

Bug in g++
Hello !
AS intructed by g++ itself, I'm sending you a bug report.
I tried to reduce the source file to the smallest file which triggers the bug.
Maybe one can make shorter but at least this file contains no '#include'
directive.

valgrind output for cc1plus
This coverage_checksum_string() indeed has slightly changed from gcc-4.0-branch
to gcc-4.1-branch, see also
http://gcc.gnu.org/ml/gcc-help/2007-12/msg00229.html
IMHO, coverage.c, line 460 is part of the problem:
459 if (offset)
460 for (;string[offset]; offset++)
461 for (i = i + offset; string[i]; i++)
462 if (string[i]=='_')
When the loop from line 461 is at end-of-string, it is restarted within loop
from line 460 with offset=9 ("9" also seen in the valgrind-output), reading
behind the end-of-string.
Don't have the REOPEN button here - please do this for me if advisable, thanks!

Similar problem here, with gcc-4.1.1:
This issue does not always end up in an ICE, but when using valgrind, some
"Invalid read of size 1" are consistently reported for cc1plus caused by
coverage_checksum_string():
$ cat gcovtest.cc
class A
{
public:
static const char* version0;
};
static const char* A_version0 = A::version0;
$ valgrind --num-callers=50 --log-file=vg.out --trace-children=yes
x86_64-unknown-linux-gnu-g++ -fprofile-arcs -ftest-coverage -c gcovtest.cc
This does not depend on x86_64-unknown-linux-gnu - it's just that I tried it
here with cc1plus having some debug info built in. I've seen similar ICEs and
valgrind output on i686-pc-linux-gnu too.

We fail to correctly order the operands for the indexed store within the loop
below. This seems to be caused by a missing REG_POINTER attribute, so the code
added for PR28690 doesn't have a chance of getting the ordering correct. An
interesting thing is that if we replace the global array with an "extern int
*reg_values;", then we get the ordering correct.
[EMAIL PROTECTED]:~/gcc/tests> cat a2-loop.c
int reg_values[1024];
void
clear_table (unsigned int n)
{
unsigned int i;
for (i = 0; i < n; i++)
reg_values[i] = 0;
}
The "bad" code gen looks like (using -O2 -S):
clear_table:
cmpwi 0,3,0
beqlr- 0
lis 9,[EMAIL PROTECTED]
slwi 3,3,2
la 9,[EMAIL PROTECTED](9)
li 11,0
li 0,0
.p2align 4,,15
.L3:
stwx 0,11,9
addi 11,11,4
cmpw 7,11,3
bne+ 7,.L3
blr
It's another question on why this isn't using an update form store and branch
on count loop, to halve the size of the loop. The loop size is particularly
glaring when you use -O2 -funroll-loops, then we get 8 indexed stores (all with
the wrong operand order) and 8 addi's...but I guess that's for another
bugzilla.

[Bug rtl-optimization/35371] Missing REG_POINTER attribute causes bad indexed load/store operand ordering
--- Comment #1 from bergner at gcc dot gnu dot org 2008-02-25 20:50 --- Created an attachment (id=15231) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=15231&action=view) Patch to GCSE to copy REG_POINTER attribute over to new pseudos. The culprit here is GCSE. When GCSE creates a pseudo to copy a reaching expression into, it fails to copy the POINTER attribute over. I'm testing the attached patch. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35371

--- Comment #19 from joel at gcc dot gnu dot org 2008-02-25 20:45 --- How early can I look at the task priority? Is it stored in some data structure that I can see with objdump before the program is run? I have yet to see anything in the debugger except 0 getting passed to task create for priority and stack size. They have to come from somewhere. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35284

[Bug target/32219] optimizer causes wrong code in pic/hidden/weak symbol checking.
--- Comment #7 from hjl dot tools at gmail dot com 2008-02-25 22:16 --- It is a compiler bug after all. From: http://groups.google.com/group/generic-abi/browse_thread/thread/4364eb484397ebe0 A hidden symbol must be defined in the same component, *if it is defined at all*. That last part is the key to the issue. In the case of a WEAK HIDDEN UNDEF symbol, it is possible for the symbol to remain undefined (or, looked at another way, it is possible for the symbol to be defined at link time as an absolute symbol with value 0). I agree with Daniel; the compiler should be aware of this possibility and generate code that will not require a dynamic relocation for this case. For a weak and hidden symbol, it is bound local only if PIC is false or it is used for branch. Otherwise, it should be treated with default visibility. -- hjl dot tools at gmail dot com changed: What|Removed |Added Status|RESOLVED|UNCONFIRMED Resolution|INVALID | Version|4.2.1 |4.3.0 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32219
