[Bug middle-end/41817] elfutils fails with may be uninitialized with -O3 -mtune=k8
--- Comment #6 from marti at juffo dot org 2009-10-27 08:58 --- (In reply to comment #5) These might not be bogus as there is extra inlining at -O3 which causes us to strip out the address taking and make search_table_entries, etc. look like real variables. True, I have changed the summary. The underlying problem I guess then is that packages use -Werror, but this warning depends on specific settings of the optimizer which changes from user to user. But don't use -Werror or don't use CFLAGS is not a useful solution either. Clearly many projects are affected by this. -- marti at juffo dot org changed: What|Removed |Added Summary|elfutils triggers bogus may|elfutils fails with may be |be uninitialized with -O3 -|uninitialized with -O3 - |mtune=k8|mtune=k8 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41817
[Bug ada/41845] New: Limited_Controlled exposes Adjust operation, which should not exist.
The following should not compile, since the Limited_Controlled has no Adjust operation and the test code uses the overriding keyword, which is supposed to catch the attempt to override non-existing operation. Other operation names are detected properly, which indicates that there is some hidden Adjust operation that should not be visible to the user code. Hint from comp.lang.ada: this hidden operation is in s-finroo.ads. Test code that should not compile, but is accepted by GNAT: with Ada.Finalization; procedure Test is package P is type T is new Ada.Finalization.Limited_Controlled with null record; overriding procedure Initialize (X : in out T); overriding procedure Adjust (X : in out T); overriding procedure Finalize (X : in out T); end P; package body P is procedure Initialize (X : in out T) is begin null; end Initialize; procedure Adjust (X : in out T) is begin null; end Adjust; procedure Finalize (X : in out T) is begin null; end Finalize; end P; begin null; end Test; -- Summary: Limited_Controlled exposes Adjust operation, which should not exist.

How about this one: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40816 I am still rather nervous about that one, as it's an ABI change. Point taken.

Simply removing one of the multiple signature is not a solution IMHO. Yes, I see what's going on.

FAIL: shared (non PIC) FAIL: shared (non PIC, load offset) FAIL: shared (PIC main, non PIC so) When generating code that is not position independent, the compiler is entitled to enable optimizations that don't retain the property of symbol pre-emption that is possible with shared libraries and position independent code. Section anchors is one optimization that doesn't retain symbol pre-emptibility in shared libraries and hence is disabled when generating PIC code. All these failures are because the tests are trying to create non-PIC .so's with section anchors turned on. The tests need to be fixed with respect to section anchors by building them with -fno-section-anchors for the arm-linux-gnueabi port. The Objective C testsuite failures should be fixed by disabling section anchors in the objective C and C++ frontend and not by disabling this in the backend. Look at the mail thread here for reference. http://gcc.gnu.org/ml/gcc-patches/2008-08/msg02194.html However that is a subject of a separate bug report, though these failures might be related to PR41617. Hence this is an INVALID bug as far as GCC is concerned and hence marking it so. cheers Ramana -- ramana at gcc dot gnu dot org changed: What|Removed |Added Status|ASSIGNED|RESOLVED Resolution||INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41684

[Bug c++/41847] warning: array subscript is above array bounds
--- Comment #3 from jakub at gcc dot gnu dot org 2009-10-27 16:53 --- The issue is that for some strange reason VRP sees the loop iterator (which is [0, 4) ) as VARYING. Then the fDum = get(b, b) is called when b is not 3, and get uses the return maLine[nRow].get(nColumn); for nRow 3. So, VRP figures that in return mpLine-get(nColumn); nColumn (== b) is necessarily [4, 65535] and reports out of bounds access on something that will really never be executed. If VRP figured that b is [0, 4), it would have been able to tell that the bb's are unreachable and not report diagnostics in that case. I wonder what related runtime failure you are talking about though, this to me looks like a false positive on something that is never executed (although not optimized out at least until *.optimized dump). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41847

[Bug lto/41767] assertion in tree-sra.c
--- Comment #9 from jamborm at gcc dot gnu dot org 2009-10-27 18:39 ---
Hi,
(In reply to comment #7)
Maybe IPA SRA gets
those two types from unrelated places?
I believe they are quite elated. The body of the function is:
bb 2:
init = c_parser_initializer (0B); [return slot optimization]
init$value_5 = init.value;
finish_decl (0, 0, init$value_5, 0, 0);
return;
The expected type is type of the RHS of the second statement
init.value while the type I get is the type of value within init.
As I said the testcase has two incompatible variants of union tree_node and
they are obviously not merged and thus not compatible.
I was not sure whether you were implying that the input was invalid or
not. If it is and we want to avoid the ICE in the simplest possible
way, we can do so with the patch below. (Of course, we might try to
instead warn or fail in some nicer way when putting the individual
pieces from different files together.)

[Bug rtl-optimization/41849] New: optimization fails when register variables are used for an interrupt
If i use global register variables that are used and updated inside an
interrupt the optimizer produces broken code.
Code example:
register volatile unsigned char timer0_h8 asm(r3);
volatile unsigned char timer0_h8_buf = 0;
void foo(void)
{
timer0_h8_buf = timer0_h8;
return;
}
ISR(TIMER0_OVF_vect)
{
timer0_h8++;
}
produces:
2432 0b5a 1092 sts timer0_h8_buf,__zero_reg__ ; timer0_h8_buf,
instead of this when no optimization is used:
3248 104a 832D mov r24,r3 ; timer0_h8.47, timer0_h8
3249 104c 8093 sts timer0_h8_buf,r24; timer0_h8_buf,

[Bug fortran/41850] New: Wong-code with optional allocatable arrays
As reported by Thomas Robitaille at
http://gcc.gnu.org/ml/fortran/2009-10/msg00220.html
the following code gives wrong-code (segfault/buserror) at run time with GCC
4.2/4.3/4.4/4.5. (4.1 does not support allocatable dummies.)
$ ./a.out
in sub1
Bus error
module test_module
implicit none
contains
subroutine sub2(a)
implicit none
real,allocatable,intent(out),optional :: a(:)
print *,'in sub2'
end subroutine sub2
subroutine sub1(a)
implicit none
real,allocatable,intent(out),optional :: a(:)
print *,'in sub1'
call sub2(a)
end subroutine sub1
end module test_module
program test
use test_module
implicit none
call sub1()
end program
The problem is that the argument can be NULL - and there is no check for the
case a == NULL; i.e. the INTENT(OUT) autodeallocation block needs to be
enclosed with a if (a !=NULL) as remarked by Dennis
(http://gcc.gnu.org/ml/fortran/2009-10/msg00221.html).
sub1 (a)
{
[...snip printing in sub1 stuff...]
{
struct array1_real(kind=4) * D.555;
if (a-data != 0B)
{
__builtin_free (a-data);
}
a-data = 0B;
D.555 = a != 0B ? a : 0B;
sub2 (D.555);
}
By the way the line D.555 = a != 0B ? a : 0B; is redundant - and also not
nice because making the alias analysis for the middle end more difficult.

--- Comment #2 from paolo dot carlini at oracle dot com 2009-10-28 00:21 --- FSF gcc-4.2.x isn't maintained anymore. I would suggest trying to reproduce the issue with gcc-4.4.x (or at least 4.3.x) or reporting to Ubuntu. -- paolo dot carlini at oracle dot com changed: What|Removed |Added Status|UNCONFIRMED |WAITING http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41853
[Bug c++/41840] g++ compiler giving error for array of pointers of abstract base class
--- Comment #3 from bangerth at gmail dot com 2009-10-28 05:17 --- (In reply to comment #0) There are many other such deviations we noticed in this compiler from the normal C++ principles. In addition to the previous answer: since gcc3.3, many many bugs have been fixed where gcc erroneously accepted code that did not conform to the C++ standard. We believe that gcc4.x is much closer to the C++ standard than 3.3 was. That said, it does occasionally happen that a bug is introduced. In that case, please open other bug reports.
