[Bug debug/46815] New: Invalid DW_AT_location for a retval instance of a class that has a virtual function
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46815
Summary: Invalid DW_AT_location for a retval instance of a
class that has a virtual function
Product: gcc
Version: 4.5.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: siddhesh.poyare...@gmail.com
Created attachment 22649
-- http://gcc.gnu.org/bugzilla/attachment.cgi?id=22649
Reproducer program to run under gdb
Problem Description:
When a local object is created from a class with a virtual function and that
object is also the retval for the function it is the local variable in, the
debuginfo generated for the object indicates that it is located in a register,
while in reality, its address is located in the register.
Steps to Reproduce:
$ cat rep.cpp
class Sequence {
public:
virtual void foo(void);
};
Sequence getSequence()
{
Sequence data;
return data;
}
$ g++ -g -c rep.cpp
$ objdump -W rep.o | less
...
3c4: Abbrev Number: 13 (DW_TAG_variable)
c5 DW_AT_name: (indirect string, offset: 0x43): data
c9 DW_AT_decl_file : 1
ca DW_AT_decl_line : 8
cb DW_AT_type: 0x31
cf DW_AT_location: 1 byte block: 53 (DW_OP_reg3)
...
Additional Information:
Attached reproducer fullrep.cpp can be used to demonstrate this problem as seen
in gdb.
1) Build fullrep.cpp: gcc -g fullrep.cpp
2) Run under gdb:
[siddh...@spoyarek gcc-foo]$ gdb -q ./a.out
Reading symbols from /home/siddhesh/gcc-foo/a.out...done.

[Bug target/45263] registers used in __do_global_ctors can get clobbered
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45263 --- Comment #11 from Michael Schulze mschulze at ivs dot cs.ovgu.de 2010-12-06 09:07:19 UTC --- (In reply to comment #9) This is essentially identical to the patch I provided for http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44617 so it looks good to me. I hadn't see that patch but you are right it's almost identical. I had two worries: Is R15 used anywhere else in startup code that might not obey the register save conventions (ie does do_global_ctors need to preserve R15) The AVR has a lot of opcodes that are not valid on registers less than 16. It doesn't look like any of these are used here, but I wasn't 100% positive that using R15 wouldn't cause problems... As far as I know r15 isn't used elsewhere in the start-up code and also your second worry seems not to be a problem, because such instructions are not used by that time. (In reply to comment #10) I strongly suggest not using R15. The ATtiny10 Family of devices (ATtiny10/4/5/9/20/40) only has R16-R31. So using R15 won't work for this class of devices. I disagree because the additional register is only in the start up code of devices that have rampz and is omitted in all other cases. The ATtiny don't have a rampz (correct me if I'm wrong) thus they are not faced with the discussed problem in general. IMO, it is absolutely possible and correct to use r15 here. It would be best if we can find a register that will for all AVR devices. Due to the compiler's C calling conventions, there are no other free registers to use without the need of pushing and popping this registers. Only registers below r16 are free to use. All other free r16,r17,r28,r29 are already in use.

[Bug libstdc++/46821] New: swapping empty classes
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46821
Summary: swapping empty classes
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: marc.gli...@normalesup.org
Hello,
I noticed in the implementation of std::tuple that when a type is empty, swap
is implemented as:
void
_M_swap_impl(_Head) { /* no-op */ }
and was wondering whether that was safe. Can't an empty type have copy, move,
assignment or swap with a non-trivial semantic? The object still has a unique
address, it could register it (in constructors) in a global data structure for
instance, and have assignment and swap change things in that data structure.

It seems expected to me that swap be called for each element, and in the usual empty case the compiler should still be able to optimize it to a no-op I guess. But really I am not sure here. I just had a look, boost also does nothing in compressed_pair. libcxx on the other hand does call swap, but that may not be a conscious decision.

Yes, in the meanwhile figured out what you meant, sorry. This passes testing
(modulo a trivial change to dg-error line numbers somewhere). Jon, what do you
think? I think should be pretty safe...

So what happens is that we set DECL_VALUE_EXPR of the NRV optimized var to RESULT_DECL, but then in cp_genericize as it is addressable change the RESULT_DECL into DECL_BY_REFERENCE decl and convert_from_reference whenever it is seen in the stmts (but don't adjust the DECL_VALUE_EXPR of the var). Which means we end up using DW_OP_reg3 instead of DW_OP_breg3 0. Either we can do something like this patch, i.e. replace DECL_VALUE_EXPR during genericization, or we could do something similar, but faster by saving pointer to the NRV optimized VAR_DECL somewhere in the lang specific stuff for the FUNCTION_DECL, or, if we can be 100% sure by finalize_nrv time that non-addressable RESULT_DECL isn't ever going to turn into TREE_ADDRESSABLE RESULT_DECL, we could assume early what cp_genericize will do and set DECL_VALUE_EXPR in finalize_nrv to INDIRECT_REF of the RESULT_DECL (which would mean somewhat invalid tree until cp_genericize is run, but perhaps nothing would notice), or we could teach dwarf2out.c if it uses DECL_VALUE_EXPR and it points to DECL_BY_REFERENCE decl that it should add indirection automatically (but then, the question is what all will actually break by that). Jason, any preferences?

[Bug middle-end/46671] [4.6 Regression] ICE in default_no_named_section, at varasm .c:5994
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46671 --- Comment #9 from Dave Korn davek at gcc dot gnu.org 2010-12-06 17:27:06 UTC --- (In reply to comment #8) sdbout.c is broken then. Quite likely, but I don't understand what it thinks it's trying to do yet well enough to be sure how. If it doesn't care in which code section it emits the stuff, it should at least not switch_to_section (text_section) if in_section != NULL (in_section-flags SECTION_CODE) != 0. I'll take a look at that possibility, thanks. I'm going to have to read up on the coff debug spec to see what it says about the matter. And in any case, it should remember in_section from the beginning of the function into say saved_section automatic var and if it was non-NULL, do switch_to_section (saved_section) at the end of the function. In fact I don't think that would help, GAS does not accept switching section in the middle of an open CFI directive block (though this is probably an implementation limitation rather than a deliberate design choice; cfi is tracked on a per-frag basis, switching to a new section and back leads to starting a new frag which doesn't have any pointer to the previously-begun cfi block.)

[Bug c++/46827] New: Heavy use of namespaces leads to cluttered and difficult to read header files
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46827
Summary: Heavy use of namespaces leads to cluttered and
difficult to read header files
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: eric-...@omnifarious.org
Header files with declarations like this:
void FooBar(System::Network::Win32::Sockets::Handle handle,
System::Network::Win32::Sockets::Error error /*, more fully-qualified param
declarations... */);
are common in certain frameworks. And using declarations, which could mitigate
this problem, are generally not considered kosher to use in header files
because they can effect the name lookup rules for header files that are
included later. typedefs inside a class that are declared private clutter up
the class' namespace and the namespace of classes derived from it.
Here is a proposed solution:
using {
// A 'using' block is a sort of way to fence names in. The only names
// that escape the confines of a using block are names that are not
// aliases for other things, not even for things that don't have names
// of their own. These are things like the declarations for new
// classes, enums, structs, global functions or global variables.
// New, non-alias names will be treated as if they were declared in
// the scope in which the 'using' block appeared.
using namespace ::std;
using ::mynamespace::mytype_t;
namespace mn = ::mynamespace;
using ::mynamespace::myfunc;
class AClass {
public:
typedef mytype_t atype_t;
AClass(const string st, mytype_t me) : st_(st), me_(me) {
myfunc(me_);
}
private:
const string st_;
mn::mytype_t me_;
};
typedef struct {
int a;
} simple;
// The effects of all typedefs, using declarations, and namespace
// aliases that were introduced at the level of this block go away
// here. typedefs and using declarations inside of nested classes
// or namespace declarations do not go away.
} // end using.
// Legal because AClass is treated as having been declared in this
// scope.
AClass a(Fred, ::mynamespace::mytype_t(5));
// Not legal, alias mn no longer exists.
AClass b(Fred, mn::mytype_t);
// Not legal, the using directive bringing in mytype_t is no longer in effect
AClass b(Fred, mytype_t);
// Not legal, the using directing bringing in myfunc is no longer in effect.
AClass c(Fred, myfunc(::mynamespace::mytype_t(5));
// Legal, only names declared at level of the using block disappear. names
// declared in nested sub-blocks (like namespace or class declarations) do not.
AClass d(Fred, AClass::atype_t(5));
// Not legal, the name simple, being an alias for an anonymous structure,
// disappeared at the end of the using block.
simple e;
Java, Python and other languages have ways of bringing in names from other
namespaces with a very limited scope. In Java, the import directive brings in
a name that only exists for the duration of the .java file. In Python, the
import statement can bring names into a module from outside, and it's
relatively easy to prevent those names from being easily exported outside the
module.
C++ needs a similar mechanism. The existence of the preprocessor the #include
directive and the C++ concept of a translation unit make the implicit scoping
of imported names problematic. So some mechanism for explicitly scoping such
temporary aliases is needed. Hence my above proposal of the 'using' block.

It should just fail the tests if there is no C++ compiler. I will see if there is a simple way to make the configure script do that.
