[Bug tree-optimization/58391] avr-gcc: Certain functions with computed goto could be inlined
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58391
--- Comment #2 from semicontinuity at yandex dot ru ---
Currently, the logic is that if the function contains computed goto, it cannot
be inlined.
My suggestion is to inline the function if
- it is static and used only once in the compilation unit
AND the address variable is static inside that function:
static void test(void) {
static void* address = L0;
goto *address;
L0: ...
...
L1: ...
}
In this case, the variable cannot be modified from outside.
Can this bug be re-opened?

This code works but is non optimal:
- It saves stack pointer to r28:r29, but later r28:r29 is never used
- Because it uses r28:r29, it saves r28:r29 to stack.
- It makes rcall .+0 and later removes 2 bytes from stack (pop r0) - this is
not necessary; rcall .+0 and pop r0's can be removed.
- Computed goto is implemented with 5 instructions, 7 words, with stack usage:
5c:80 91 60 00 ldsr24, 0x0060
60:90 91 61 00 ldsr25, 0x0061
64:8f 93 pushr24
66:9f 93 pushr25
68:08 95 ret
Instead, it could be implemented with
ldsr30, 0x0060
ldsr31, 0x0061
ijmp
with 3 instructions, 5 words, no additional memory access, but with clobbering
of r30:r31 instead of r24:r25 which is OK.

[Bug libstdc++/58403] __normal_iterator triggers odr-use
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58403 --- Comment #7 from Jonathan Wakely redi at gcc dot gnu.org --- http://gcc.gnu.org/wiki/VerboseDiagnostics#missing_static_const_definition You odr-use a static member variable, so it must have a definition. The linker error is your fault for not defining the static member, not the library's fault for using a reference parameter. If you add the missing definition the program links: constexpr std::iterator_traitsstd::string::iterator::difference_type A::a; So I have no objection to changing __normal_iterator to take the parameter by value, but taking it by reference is not a bug. It is unspecified whether it += A::a is an odr-use or not. Your program will also fail to link if you do this: std::max(A::a, A::a); But clearly we're not going to change std::max, that would be non-conforming.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58403 --- Comment #8 from Paolo Carlini paolo.carlini at oracle dot com --- Hi, (In reply to Jonathan Wakely from comment #7) http://gcc.gnu.org/wiki/VerboseDiagnostics#missing_static_const_definition You odr-use a static member variable, so it must have a definition. I may be missing some C++11 specifics, but I understand the bug report this way: since the implementors have the leeway of defining those operators as taking the arguments by value or be const ref, and since we are essentially talking about ptrdiff_ts, which don't really want by ref, why using by const ref unnecessarily which introduces an odr-use? If you like not a proper bug, but a QoI issue, a rather simple one. Taking also into account, as submitter correctly noticed, that we have already be value for move_iterator and reverse_iterator. Does this make sense?

Ultimately I need to be able to reproduce the failure. So far I've been unable to do so on the ia64 boxes I have direct access to. Note I'm just doing a configure; make, so if you're using different options, I'd need to know about those. Alternate approaches would be for you to make a box available which exhibits the problem or for you to help more with the debugging by identifying what file/module is getting mis-compiled. As you probably know, it's rarely the file showing the comparison failure.

The following program is correct in C++11, but uses a deprecated language
feature. According section D.3, paragraph 1:
The implicit definition of a copy constructor as defaulted is deprecated if
the class has a user-declared copy assignment operator or a user-declared
destructor. The implicit definition of a copy assignment operator as defaulted
is deprecated if the class has a user-declared copy constructor or a
user-declared destructor.
G++ should emit a warning in C++11 mode.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58407 --- Comment #4 from Jonathan Wakely redi at gcc dot gnu.org --- I don't think anything in appendix D apart from auto_ptr does. The warning would be useful to help find places where defaulted definitions could be added, but I'm not sure I'd want it enabled by -Wall. YMMV.
[Bug c++/58408] New: [C++11] __thread + trivially_constructible - error
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58408
Bug ID: 58408
Summary: [C++11] __thread + trivially_constructible - error
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ppluzhnikov at google dot com
Google ref: b/10727382
This source:
class Test {
public:
Test() = default;
Test(char *b) { }
int i;
};
__thread Test test;
fails to compile with current trunk (g++ (GCC) 4.9.0 20130911 (experimental)):
g++ -c -std=c++11 /tmp/t.c
/tmp/t.cc:8:15: error: non-local variable 'test' declared '__thread' needs
dynamic initialization
__thread Test test;
^
/tmp/t.cc:8:15: note: C++11 'thread_local' allows dynamic initialization and
destruction
I don't see a good reason to reject this source -- the required dynamic
initialization is defaulted.

I'll try to reproduce the bug within the vegastrike build chain next and then make sure the new compiler works.
