--- Comment #2 from jakub at gcc dot gnu dot org 2010-08-26 07:33 --- That's not the main problem here. The problem is that this is an aggregate and we SRA only automatic vars, not global vars. And it isn't constant either (neither declared, nor actually, so can't be detected as constant). Special handling of main would just add info that it is called only once in the lifetime of the program. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45410

Confirmed.
The tracer seriously messes up virtual operands. I'm not sure the copy
tables work like the author thought they would.
After duplicating we have
virtual int S::vm() (struct S * const this)
{
int state;
int D.2129;
int retval.0;
bb 2:
# .MEM_8 = VDEF .MEM_7(D)
retval.0_1 = foo (state);
switch (retval.0_1) default: L3, case 0: L0, case 1: L1
L0:
# .MEM_9 = VDEF .MEM_8
bar ();
bb 7:
# .MEM_14 = PHI .MEM_9(3)
if (this_3(D) != 0B)
goto bb 8;
else
goto bb 6 (L3);
bb 8:
# .MEM_15 = VDEF .MEM_5
S::~S (this_3(D));
# .MEM_16 = VDEF .MEM_12
operator delete (this_3(D));
bb 9:
# .MEM_17 = PHI .MEM_13(8)
# VUSE .MEM_10
D.2129_18 = state;
return D.2129_4;
# .MEM_5 = PHI .MEM_8(2)
L1:
if (this_3(D) != 0B)
goto bb 5;
else
goto bb 6 (L3);
bb 5:
# .MEM_12 = VDEF .MEM_5
S::~S (this_3(D));
# .MEM_13 = VDEF .MEM_12
operator delete (this_3(D));
# .MEM_10 = PHI .MEM_8(2), .MEM_5(4), .MEM_13(5), .MEM_5(7)
L3:
# VUSE .MEM_10
D.2129_4 = state;
return D.2129_4;
}
see how virtual SSA form is messed up (and no symbol is marked for
renaming).

You didn't say which version of GCC you're using, but it doesn't really matter
because these options have been in place for many years.
(In reply to comment #0)
(5) I'm lazy and don't want to locate the applicable man page
Here it is:
http://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html
(9) no easy way to control 'unused warning' spew is one of the biggest
complaints on the crypto++ mailing list when building for *nix
This gives neither unused variable not unused parameter warnings:
void f(int) {
int j = 0;
(void)j;
}
But if that's not easy enough, just use relevant -Wno-... option.

Hi, I agree that const void * is the better parameter for _mm_prefetch, but it leads to incompatible code. ICC defines _mm_prefetch as: void _mm_prefetch(char const *, int) and MSVC documents it as: void _mm_prefetch(char * p , int i ) (which is even worse).

then go on to do different optimizations and generate very

[Bug fortran/45417] New: DEALLOCATE: No error when deallocating a target
See thread starting at http://j3-fortran.org/pipermail/j3/2010-August/003747.html The first example is valid (state == 0), the second valid (state /= 0), and the third one is invalid. gfortran produces, http://j3-fortran.org/pipermail/j3/2010-August/003753.html, 0 crash crash. Expected: The second example produces state /= 0. Variant (works, should be state == 0): http://j3-fortran.org/pipermail/j3/2010-August/003754.html The problem is that our array descriptor does not save whether a variable has been allocated or just associated with a named target.

[Bug c++/45418] New: [C++0x] can't initialize array of non-trivial type with brace-init
Hello,
this may just not be implemented yet, but in case it was missed:
struct A1 {
};
struct A2 {
A2(){}
};
template class T struct B {
T tab[1];
B(T const t):tab({t}) {} // here
};
int main(){
int i=2;
Bint b{i};
A1 a1;
BA1 e1{a1};
A2 a2;
A2 c[1]{{a2}};
BA2 e2{a2}; // fails
}
complains about a bad array initializer, whereas with a trivial type A1 or a
builtin int, it works fine.

--- Comment #1 from janus at gcc dot gnu dot org 2010-08-26 17:54 --- The dump shows that the first call to 'get_fmt' is executed dynamically as 'a.$vptr-get_fmt(...)', while the ones inside the SELECT TYPE block are resolved statically to 'd_base_get_fmt'. For the TYPE IS clause this is fine, but not so for CLASS DEFAULT, where a polymorphic call should be generated. F08 quotes (chapter 8.1.9.2): Within the block following a TYPE IS type guard statement, the associating entity (16.5.5) is not polymorphic (4.3.1.3), has the type named in the type guard statement, and has the type parameter values of the selector. Within the block following a CLASS IS type guard statement, the associating entity is polymorphic and has the declared type named in the type guard statement. The type parameter values of the associating entity are the corresponding type parameter values of the selector. Within the block following a CLASS DEFAULT type guard statement, the associating entity is polymorphic and has the same declared type as the selector. The type parameter values of the associating entity are those of the declared type of the selector. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45420

[Bug fortran/45420] [OOP] poylmorphic TBP calls in a CLASS DEFAULT clause
--- Comment #2 from janus at gcc dot gnu dot org 2010-08-26 19:55 ---
It turns out this bug is rather easy to fix. The problem was the we used the
temporary needed for the TYPE IS clause also in the CLASS DEFAULT clause (where
we need none). The following patch fixes it (haven't checked for regressions
yet):
