[Bug c++/23648] New: Spurious uninitialized variable warnings at -O1 and higher
The compiler issues spurious warnings such as warning: '__cur' might be used
uninitialized in this function, where on the corresponding line, __cur is the
lvalue in an assignment. The warnings are not issued at -O0. I noticed this
problem when dealing with nested STL containers.
This is not a duplicate of bug 5035.
Here is the test code:
#include vector
#include set
int main(int, char**)
{
std::vectorstd::vectorstd::setint basis;
basis.clear();
return 0;
}
I'll attach the preprocessed output. Command line and compiler output follows:
% g++ -v -save-temps -Wall -o uninitialized -O2 uninitialized.cc

[Bug rtl-optimization/22568] Should use cmov in some stituations
--- Additional Comments From rguenth at gcc dot gnu dot org 2005-08-31 09:40 --- With new tree-codes instead of using COND_EXPR we may use the tree-vectorizers if-conversion and make expand preserve the conditional moves. Also it shouldn't be too hard to hack rtl if-conversion to handle the case of exactly two set's in the then/else block, too, and that may turn out to be profitable always. Is there any arch whose conditional move will kill condition codes? RTL is not my best friend (yet), but ifcvt doens't look too bad either ;) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22568

[Bug c++/13377] [3.4 regression] unexpected behavior of namespace usage directive
--- Additional Comments From reichelt at gcc dot gnu dot org 2005-08-31
11:07 ---
For the testcase
==
namespace N
{
int i;
}
int i;
using namespace N;
void foo() { i; }
==
we now get
ambig4.C: In function 'void foo()':
ambig4.C:10: error: use of 'i' is ambiguous
ambig4.C:6: error: first declared as 'int i' here
ambig4.C:3: error: also declared as 'int N::i' here
ambig4.C:10: error: 'i' was not declared in this scope
Btw, this is the testcase which was a regression from GCC 3.3.x.
For the testcase
==
namespace N
{
namespace M {}
}
namespace M {}
using namespace N;
using namespace M;
==
we now get (since the patch for PR23586 is also in place):
ambig5.C:13: error: use of 'M' is ambiguous
ambig5.C:10: error: first declared as 'namespace M { }' here
ambig5.C:7: error: also declared as 'namespace M { }' here
ambig5.C:13: error: 'M' is not a namespace-name
ambig5.C:13: error: expected namespace-name before ';' token
This is still a little suboptimal (first we say it's ambiguous,
then we say it's not declared/not a namespace-name), but I think
the user can figure out the problem now.
So this is fixed on mainline and the 4.0 branch.

Confirmed, this is a regression from 3.4.0 where this worked just fine.
before 3.4.0, we rejected this with:
C.java:2: error: Class `C' must override `C.methB()' with a public method in
order to implement
interface `B$BInt'.
void methB() { }
^
1 error
Actually that is correct, we should error out, even fixing that bug I still get
an ICE.
I will report a bug for that one soon too.

[Bug ada/23519] Dividing fixed point number by zero returns zero.
--- Additional Comments From dje at gcc dot gnu dot org 2005-08-31 16:18 --- On PowerPC, one needs to emit arithmetic instructions using the mnemonic with the o suffix to test for overflow (including divide by zero). The GCC language and/or front-end would need to inform the backend that this is required. Currently GCC cannot represent that overflow test or divide by zero test is required, e.g., with a different RTL code. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23519

[Bug c/23658] New: bogus warning for missing return value
The testcase below was distilled from GMP source code (thanks to TG).
Consider
inline int foo (void){ if (1) return 0; }
int bar () { return foo (); }
compile with -Wall -O2 -c. Gcc spits out
tg.c: In function 'bar':
tg.c:2: warning: control may reach end of non-void function 'foo' being inlined
which clearly is bogus as the branch is *always* taken.

[Bug java/23620] [4.0/4.1 Regression] Segfault compiling inner interfaces
--- Additional Comments From wmahan at gmail dot com 2005-08-31 16:23 --- I guess that is a bug in my test case. I didn't notice because it compiles fine with gcc 4.0.1 when A.class and A$AInt.class are not present. The problem seems to be that when check_inner_circular_reference() is looking for circular references, it segfaults when it gets to the tree for A, which has -type.binfo == NULL. I'm not sure if that's supposed to happen. Here's a patch that fixes the bug for me, but it may just fix the symptom rather than the real problem. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23620

[Bug tree-optimization/23659] New: Should able to add dereferencing (statements with VUSE) without rerunning may_alias
An example of this comes from PR 18298:
extern C int strcmp (const char*, const char*);
char s[2048] = a;
inline bool foo(const char *str) {
return !strcmp(s,str);
}
int main() {
while(!(foo())) {
s[0] = '\0';
}
return 0;
}
In fab, we replace:
# VUSE s_1;
D.1754_4 = strcmp (s[0], [0]);
With
D.1777_6 = (const unsigned char *) s[0];
D.1778_9 = *D.1777_6;
D.1779_3 = (int) D.1778_9;
D.1754_4 = D.1779_3;
And the D.1778_9 = *D.1777_6; statement does not have a VUSE which causes
wrong code if we
have a V_MAY_DEF/V_MUST_DEF above (which happens in the testcase).
The main reason why I am asking this question so that in the tree combiner, I
don't want to rerun
may_alias after each time I run the tree combiner which just becomes too
expensive.
An example for the tree combiner would be:
int f(char *a)
{
int b = strlen(a);
return b == 0;
}
