[Bug c++/26102] New: [4.2.0 regression] using Base::member nonsense
Consider the following reduced testcase:
template class T struct B1 { int i(); };
struct B2 { int i(); };
template class T struct C : public B1T, public B2
{
using B2::i;
void f()
{
i();// fails, should be accepted
i.i(); // accepted, should fail
}
};
With today's trunk this gives:
t.cpp: In member function #8216;void CT::f()#8217;:
t.cpp:10: error: no match for call to #8216;(B2) ()#8217;
i seems to be resolved as the base class B2,
as opposed to its member i()

For reasons that I don't understand, the HP linker replaces the code sequence generated by GCC .CALL ARGW0=GR b,l $$dyncall,%r2 copy %r2,%r31 with 0x008d705c htab_create_alloc+92: be,l 27d68(sr4,r0),%sr0,%r31 0x008d7060 htab_create_alloc+96: copy rp,r31 r2 and rp are the same. The b,l is a 22-bit pc-relative branch. It can only use r2 as the link register. The linker has gone and substituted the be,l branch which uses r31 as the link. As a result, r2 isn't set by the call and the code returns a second time to the return point of the previous call. If I was certain that the linker was always going to do the substitution, the the copy could be adjusted. However, the linker can only do the substitution when the offset is a 17-bit offset. When I wrote, the code to use the 22-bit branch, I am fairly certain that I checked that the linker didn't do the be,l substitution when a b,l was used. I guess this optimization has to be removed on hpux. Dave -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26109

[Bug tree-optimization/21463] min/max and references
--- Comment #7 from pinskia at gcc dot gnu dot org 2006-02-05 21:09 ---
The problem here is actually not I would I had orginally thought but instead
the following issue:
struct f
{
int i;
};
int g(int i, int c, struct f *ff)
{
int *t;
if (c)
t = i;
else
t = ff-i;
return *t;
}
We don't change the *t into the i and ff-i which causes the min/max not be
reconized. This is related to PR 19431 which is a similar issue.

--- Comment #36 from steven at gcc dot gnu dot org 2006-02-05 21:37 --- I think the easiest way to fix this is to limit the length of the EQUIVALENCE chains somehow. I've collected some numbers about the number of elements in the EQUIVALENCE chains of GCC 2.7.2 (which is the version of GCC in SPEC2000): frequency # of elements 20342 0 43484 1 13230 2 1701 3 456 4 207 5 81 6 44 7 24 8 18 9 4 10 4 11 4 12 4 13 2 14 2 15 2 16 So if we cut off the element lists at, say, 20 elements, we shouldn't be missing a significant number of optimizations.

[Bug c++/26110] New: using directive breaks ADL
When compiling the following code, an incorrect binary is produced:
--- BEGIN CODE ---
namespace test {
double f(double f)
{
return f + 1.;
}
}
double f(float d)
{
return d;
}
int main(int argc, char *argv[])
{
using test::f;
float d = 2.;
double result1 = f(d);
double result2 = test::f(d);
return 0;
}
--- END CODE ---
The line
double result1 = f(d);
should call the function double f(float d), instead it calls the function
double f(double f) in namespace test.
This breaks argument dependent lookup. The using directive should only make
visible the function in namespace test, but not hide the global one.
If you replace using test::f with using namespace test, then everything
works correctly.
gcc -v gives me:

--- Comment #2 from fxcoudert at gcc dot gnu dot org 2006-02-05 22:19 --- OK, now I understand: huge(0._10) is 1.1897314953572317650E+4932. But when you write it with a format not long enough, you may (as was the case) write it as 1.189731495357232E+4932, which is larger than huge(0._10). So indeed, when you read it back, it's out of the range accepted for real(10) variables. Changing the default format for these variables will indeed get rid of all this.

--- Comment #2 from dg001 at t-online dot de 2006-02-05 23:14 --- The first statement in my code doesn't use any namespace double result1 = f(d); So ADL should take the function with the signature (float d), which is in global namespace. There is of course a second statement in my code: double result2 = test::f(d); and yes, this works correctly. So please have a closer look at the *first* statement, which doesn't compile to correct code. -- dg001 at t-online dot de changed: What|Removed |Added Status|RESOLVED|UNCONFIRMED Resolution|INVALID | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26110

--- Comment #3 from pinskia at gcc dot gnu dot org 2006-02-05 23:41 --- This has nothing to do with ADL really. using test::f; forces to use test::f when doing f(a) in that scope since that is the f in that scope.

--- Comment #4 from dg001 at t-online dot de 2006-02-06 00:17 --- I had a look at ISO/IEC 14882:2003(E). That is the ANSI/ISO Standard for C++. Paragraph 3.4.2 deals with Argument-dependent name lookup. In section 2 I read: The sets of namespaces and classes is determined entirely by the types of the function arguments (and the namespace of any template template argument). Typedef names and using-declarations used to specify the types do not contribute to this set. So a using-declaration should not alter the way argument-dependent name lookup works. I came across this issue when I tried to compile an example from Scott Myers, Effective C++, 3rd edition, item 25. There is a using-declaration on page 110, that doesn't work with gcc version 4.0.2. Again, the using-declaration only makes the function, if it be my f(...), Myers or stl's swap(...), visible in the scope. But the compiler takes the arguments of the function call into consideration, which of the visible functions fits best. The example I gave above is very simplified. But you can replace the fundamental types of double and float with real classes, and the problem persits. I just didn't want to post the contents of 5 files (header + implementation) here. I'd be glad, if you looked up my references. I still claim that the beforementioned version of gcc doesn't conform to the C++ standard. -- dg001 at t-online dot de changed: What|Removed |Added Status|RESOLVED|UNCONFIRMED Resolution|INVALID | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26110

--- Comment #5 from pinskia at gcc dot gnu dot org 2006-02-06 00:29 --- Why do you think ADL has anything to do with finding ::f here? From the standard: -- If T is a fundamental type, its associated sets of namespaces and classes are both empty. So we cannot find ::f here at all. -- pinskia at gcc dot gnu dot org changed: What|Removed |Added Status|UNCONFIRMED |RESOLVED Resolution||INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26110
